Introduction
The geological setting of Serbia is very complex. It is char-
acterized by a large number of rock formations of varied
lithological composition, petrochemical features, age and
metallogenic specialization.
The mineral resources of Serbia and the metallogenic or tec-
tonic units within which they are located are constituent parts
of regional metallogenic and geotectonic units larger than its
territory. Accordingly, the position, time and conditions of the
formation of the mineral resources of Serbia depended to a
large extent on the geotectonic evolution of that broad territo-
ry and the accompanying volcanic, sedimentary and metamor-
phic processes. The importance of the mineral deposits in the
above mentioned metallogenic and geotectonic units varies
depending on their territorial distribution, their type and envi-
ronment, the extent of their occurrences, the association of the
ore and accompanying elements, and the chronological span
of their formation.
The largest geotectonic units in the territory of Serbia are:
the Dinarides, the Vardar Zone, the Serbo-Macedonian Mas-
sif, the Carpatho-Balkanides and the Pannonian Basin (Dimi-
trijević 1982, 1997). From the metallogenic point of view,
they are all incorporated into the Tethyan-Eurasian Metallo-
genic Belt (TEMB), or, in the broader scale into the so-called
North-Eastern Mediterranean Sector (Janković 1967, 1974,
1990, 1997). A more detailed territorial grouping of these
units is based on an analysis of the relationship between the
mineral deposits and the geological environment with which
they are genetically and territorially associated (Janković
1990; Janković et al. 2003).

Abstract: The mineral resources of Serbia were formed by complex processes of metallogenic development and in
various geological epochs (Pre-Baikalian to Alpine). Their overview in this paper is supported by the simplified
Metallogenic map of Serbia showing virtually selected mineral deposits, as well as by maps of the most important fossil
fuel resources. The most important group of metallic mineral resources of Serbia includes Cu, Pb-Zn, Au, Ag, Sn, Mn,
U, Mo, Ti, W, Co, Sb and Fe ores. The important group of industrial mineral resources include: bentonite, boron
minerals, refractory clay, gypsum and anhydrite, diatomite, dolomite, zeolite, kaoline, quartz sand, cement marl, ce-
ramic clay, limestone, magnesite, phosphates, chrysotile-asbestos, building industry granulates (natural and crushed)
and decorative stone. Serbia also has significant resources of fossil fuels, particularly coal and oil shale. The soft brown
coal (lignite) is of great economic importance since it represents the main source for the production of electric energy.
The remaining petroleum potential of the Pannonian Basin in Serbia indicates that modern exploration may result in the
discovery of significant additional reserves of oil and gas. Production of shale-oil also has great potential, but it depends
on future detailed valorization of various factors.
Key words: Serbia, potential, reserves, ore, industrial minerals, oil, gas.
The geology of Serbia
The territory of Serbia covers various geological units of
composite structure and complex tectonic interrelations. The
ideas about its geological subdivision have changed, mostly
in relation to prevailing geotectonic concepts – from
Kober’s orogene (1952) and Stillean magmatic and orogenic
phases to several new models of plate tectonic ideas in the
early eighties (Aleksić et al. 1971; Dimitrijević & Dimitri-
jević 1973; Dimitrijević 1974a,b; Grubić 1974; Dimitrijević
& Grubić 1977; Dimitrijević & Djoković 1979). Most re-
cently a subdivision of the Serbian territory has been pro-
posed by Karamata et al. (1992, 1997), Karamata & Krstić
(1996), based on the terrane-concept.
According to Dimitrijević (1997), the territory of Serbia is
subdivided into: the Dinarides, the Vardar Zone, the Serbo-
Macedonian Massif, the Carpatho-Balkanides and Neogene
sediments which cover the products of the older tectonic
events (Fig. 1).
Dinarides
– Four main geotectonic units can be distin-
guished in the Serbian part of Dinarides: The East Bosnian-
Durmitor Block, Drina-Ivanjica Element, Studenica Slice and
Ophiolite Belt.
The East Bosnian-Durmitor Block lies in the extreme
southwestern part of Serbia. It covers a very small portion of
Serbia, and extends into Montenegro and Bosnia. It is char-
acterized by a complex nappe structure. The Lower Triassic
sediments (mostly sandstones), Anisian dolomites, bioclastic
limestone, red Bulog Limestone and volcanics prevail in this
unit. The Ladinian mostly begins with chert and tuffs, fol-
lowed by relatively thin cherty limestone, dolomite and reef
346
JELENKOVIĆ, KOSTIĆ, ŽIVOTIĆ and ERCEGOVAC
limestone. In the Upper Triassic, a platform with a thick car-
bonate succession is characteristic for the SW area. The Ju-
rassic is carbonate dominated; Ophiolitic mélange occurs
under rather curious conditions. The Cretaceous is mostly
absent.
The Drina-lvanjica Element consists of two intensely tec-
tonized Paleozoic blocks: the Drina block in the northwest
and Ivanjica block in the South, overlain by Triassic rocks
on the southwestern and eastern margins (Triassic platform).
In the western and northwestern parts of the belt some shal-
low marine Upper Cretaceous sediments occur. The eastern
boundary of the element is fringed by products of trough fly-
sch, most probably deposited in the back-arc basin of the
boundary toward the Vardar Ocean. Extensive volcanic ac-
tivity took place in both Drina and Ivanjica blocks during the
Miocene, with shallow granodiorite intrusions of Golija.
The Studenica Slice runs from the West Morava over the
Čemerno Mountain. Its eastern boundary is mostly covered
with allochthonous ultramafics; the western boundary is
marked by Senonian ophiolite mélange in contact with Se-
nonian flysh of the Dinarides. The Studenica slice extends to
the south across Čemerno, with characteristic metamorphic
rocks. They are progressively metamorphosed by Čemerno
granitoids, which occur as a swarm of hectometric masses,
representing apical parts of conformable granitic intrusions.
The Ophiolite Belt occurs in the Inner Dinarides (Dinar-
ides—Albanides and the Othris Zone in Greece). As the scar
of a Middle Triassic to uppermost Jurassic oceanic tract, it
has a base of somewhat deeper-water Mesozoic limestones,
overlain mostly by oceanic siliceous shales and chert of the
continental slope, followed by the Ophiolitic Mélange. Large
obducted ultramafic masses, with hot lower contacts and
fragments of the whole oceanic crust are characteristic.
The Vardar Zone
– This zone is situated between the
Serbo-Macedonian Massif (SMM) on the East and the Dinar-
ides on the West. Its eastern boundary is marked by longitu-
dinal reverse dislocations along which the SMM is
superposed over the Vardar Zone. Along its western zone
with the Dinarides, the boundary of the Vardar Zone is not
distinctly outlined like along the SMM. The Vardar Zone is
thrust over the Pelagonian Massif/the Dinarides, but to the
north the terranes of the Vardar Zone are obducted in the
form of the Kopaonik overthrust to the WSW onto the Golija
Zone (Resimić et al. 2000).
The geological column of the Vardar Zone consists of
small blocks of crystalline schists, Carboniferous Veles
Beds, Jurassic ultramafics, hemipelagic and eupelagic Trias-
sic sediments, diabase-chert formations, Jurassic granitoids,
Lower and Upper Cretaceous flysch and Tertiary calc-alka-
line volcano-intrusive complexes. Signs of three main phas-
es of plication are recognized in the Vardar Zone: Upper
Carboniferous, Cimmerian and post-Senonian (Grubić
1980).
According to Dimitrijević (1997), the Vardar Zone is com-
posed of several blocks differing in composition, geological
history and origin. In the W-E direction, it can be divided
into the External Subzone (Srem, Jadar and Kopaonik
blocks), Central Subzone and (conditionally) Internal Sub-
zone.
The Serbo-Macedonian Massif (SMM)
– This geotectonic
unit consists of two complexes of crystalline schists – the
lower and the upper one. The lower complex is composed of
rocks pertaining to the amphibolite facies group (mica gneiss,
micaceous schists, quartzites, some marble and migmatite),
with migmatization and Paleozoic granitoids; it is covered in
places by shallow-marine Cretaceous and the Eocene clastics
of the Pčinja Group. The complex is ~ 11 km deep. The upper
complex of the SMM ( ~ 5 km deep) bears Riphean-Cambrian
greenschists, covered by weakly metamorphosed Ordovician
to Carboniferous strata. It is intruded by granitoids of Paleozo-
ic (Vlajna) to Tertiary age (Surdulica) (Dimitrijević 1997).
The SMM has a tectonic relation to the Vardar Zone and the
Carpatho-Balkanides. Crystalline areas of the SMM are thrust
over adjacent tectonic units. They were moved particularly
strongly to the west, affecting the western periphery of the
SMM that was heavily reworked tectonically and adjusted to
the structural features of the Vardar Zone (Grubić 1980).

MINERAL RESOURCES OF SERBIA
The Carpatho-Balkanides
– Four main groups of geotec-
tonic units can be isolated in the Serbian part of Carpatho-
Balkanides: Suprageticum, Geticum, Upper Danubicum
(Infrageticum) and Lower Danubicum (Dimitrijević 1997).
The Suprageticum consists of the Gornjak-Ravanica Zone
(Silurian and Devonian sediments, Permian red sandstone
and Mesozoic with numerous breaks in sedimentation).
The Geticum is made up of the Ruj Zone (Upper Jurassic
Flysch), Suva Planina Zone (Devonian—Lower Carbonifer-
ous Flysch, Permian sandstone, thick Jurassic and Creta-
ceous carbonates), Kučaj Zone (clastics from Cambrian to
Devonian, flysch, Permian and Triassic clastics, Jurassic-
Lower Cretaceous carbonates, thin Upper Cretaceous),
Timok Eruptive Area, and the Tupižnica—Tepoš Unit (Meso-
zoic carbonates with numerous breaks).
The Upper Danubicum is composed of the Poreč Zone
(highly complex relations of Cambrian to Aptian rocks; Deli
Jovan Gabbro), Miroč Zone (in part the whole Paleozoic; Ju-
rassic and Cretaceous varying in thickness, with breaks);
Krajina Zone (Sinaia Beds, Mokranje Flysch) and the Stara
Planina (semimetamorphic Paleozoic, Permian red sand-
stone, Mesozoic up to the Cretaceous; Zaglavak Gabbro;
granitoids of various ages).
The Lower Danubicum represents the Vrška Čuka Zone
(Cambrian? greenschists, very thin Carboniferous and Per-
mian, thin Jurassic and Cretaceous).
The Pannonian Basin
– The Pannonian Basin covers the
northern part of Serbia. It is filled with lacustrine and marine
Tertiary and continental Quaternary sediments. In the south-
eastern and northern Banat and northern Bačka (part of Ti-
sia) crystalline schists and granitoids build up to basement of
the Pannonian Basin. Mesozoic sediments prevail in the
greater part of the middle and southern Banat, with the Torda
Flysch, and ophiolites along the subzone and block bound-
aries of the Vardar Zone.
The origin and evolution of mineralization
All mineral deposits and occurrences in Serbia are concen-
trated into four regional metallogenic units that spatially ex-
tend beyond the territorial boundaries of the country: 1 –
the Dinaric metallogenic province (DMP) covering western
Serbia, 2 – the Carpatho-Balkanian metallogenic province
(CBMP) in the north-eastern part of the Serbia, 3 – the Ser-
bo-Macedonian metallogenic province (SMMP) in the cen-
tral part of the Serbia, covering the terrains of the Vardar
Zone, the Serbo-Macedonian Massif and eastern part of Di-
narides and 4 – the Dacian metallogenic province (DcMP)
that include an extremely small area in the far north-eastern
part of Serbia: only small deposits of kaolin in Miocene
sediments are known in DcMP (Janković 1977, 1982). The
Dinaric, Serbo-Macedonian and Carpatho-Balkanian metal-
logenic provinces can be subdivided into several metallo-
genic zones, ore districts and ore fields, some of which have
specific features associated with the origin of the ore depos-
its.
A simplified metallogenic map of Serbia showing the po-
sition of the main metallogenic units, mineral deposits and
some important metallic and industrial mineral occurrences
is presented in Fig. 2.
According to the contemporary knowledge of plate tecton-
ics and of the geotectonic and metallogenic development of
the terrain in Serbia, its mineral resources can be classified
as: 1 – Deposits related to intracontinental rifting; 2 – De-
posits related to ophiolite complexes; 3 – Deposits of sub-
duction
related
setting
and
4 – Deposits
of
continent-continent collision-related setting (Janković 1990).
Apart from magmatogenic ore deposits, some other mineral
deposits (magnesite, clays, etc.) hosted by Neogene basins
had been identified in the collision-related environments in
Serbia.
Deposits related to intracontinental rifting. The pro-
cesses of rifting, both of the initial and advanced stages, last-
ed from Early to Late Triassic (Knežević et al. 1997:
“aborted rifts”) have been suggested, but in some sectors of
Serbia (Dinarides, Vardar Zone) continued lateral spread of
the sea-floor led to the opening of the ocean (Late Triassic—
Late Jurassic). Tectonic setting is characterized by elongated
and mostly subparallel horst-graben structures (Janković
1987; Janković et al. 1997).
Two principal groups of magmatic rocks, both intrusive
and volcanic, are distinguished in relation to intracontinen-
tal rifting and opening and oceanic spreading: 1 – quartz-
keratophyres, porphyrites and albite-granites (processes of
intracontinental rifting) and 2 – diabases and basalts (spi-
lites) – processes of opening and oceanic spreading
(Knežević et al. 1997).
The predominant types of ore mineralization in relation to
intracontinental rifting are lead-zinc and subordinate copper.
From the genetic point of view, they are classified as fol-
lows: 1 – hydrothermal volcano-sedimentary, hydrothermal
stockwork and vein types (Čadinje and Bobija deposits –
hydrothermes related to subcrustal magmas strongly contam-
inated by crustal material+warmed descending water. Ore el-
ements are mostly leached from the host rocks); 2 –
hydrothermal massive sulphide ores and hydrothermal veins
in relation to ophiolite mélange (diabase-chert formation –
Putnik 1981; Karamata 1986) of Western Serbia (Lajkovača
deposit – descending marine water warmed and included
into conventional systems. Ore elements are mostly leached
from the host rocks).
In relation to processes of intracontinental rifting and
opening and oceanic spreading, several other groups of min-
eral deposits in addition to lead-zinc and copper, are present:
a – high temperature hydrothermal Fe-veins and lenses;
b – Fe-Mn oxides and carbonates accompanied by minor
Pb-Zn and Fe sulphides; c – barite deposits, d – mercury
deposits and e – mineral deposits associated with weather-
ing crust (bauxite deposits developed on the karstified lime-
stone).
Ore deposits related to ophiolite complexes. When the
lateral spreading of continental crust continues from the
stage of intracontinental rifting, new oceanic crust begins to
form. The floor of the ocean has many tectonic elements (the
active spreading axes, hot-spot etc.) that are considered to be
significant metallotects of ore deposits Jurassic in age (Jan-
ković et al. 1997).

MINERAL RESOURCES OF SERBIA
The ophiolites form two distinct belts: the Western Belt lo-
cated in the Inner Dinarides (Dimitrijević 1997), and the
Eastern Belt, extends from the Vardar Zone to Asia. The
metallogeny of these ophiolitic complexes is closely associ-
ated with their petrochemical features and geotectonic set-
tings. The ophiolites of the Western Belt are similar to the
present ocean floors. They are characterized by the domi-
nance of lherzolite peridotite, gabbro-pyroxenite and ortho-
pyroxenite (Karamata et al. 1980). Endogenous ore deposits
related to these ophiolitic complexes are mostly the Ni-Co-
Cu-Fe sulphides, pyritic cupriferous deposits, sporadically
magnetite deposits and minor gold mineralization, but with-
out major chromite deposits. The ophiolites of the Eastern
Belt consist mainly of Mg-rich peridotite and dunite. Their
metallogeny is characterized by major chromite and signifi-
cant pyritic cupriferous deposits, as well as the major magn-
ezite and chrysotile asbestos deposits, locally nickel silicate
and nickeliferous iron deposits.
Deposits from subduction—related settings (subduction
beneath the active continental margin; Cretaceous). Many
deposits in the eastern Serbian part of the Carpatho-Balka-
nian metallogenic province are associated with horst-graben
structures formed above subducted oceanic lithosphere un-
der the Eurasian plate, following the closure of a Tethyan
branch during the Early Cretaceous (Janković 1990).
The most important deposits (Cu, Au, and rare Pb-Zn) relat-
ed to subduction-related settings are of the porphyry copper,
skarn type and volcano-hydrothermal (massive-sulphide): Bor
deposit, Majdanpek deposit, Veliki Krivelj deposit (Bor meta-
llogenic zone) and Ridanj-Krepoljin Zone (Reškovica, Antina
Čuka etc). The ore elements are mostly leached from the host
rock (andesites and analogue plutonites; magmatic arc above
the subduction zone or of the rifts over the subduction zone) in
the convectional systems by fluids derived from the subducted
oceanic plate and partly dehydrated continental crust mixed
with descending solution (Knežević et al. 1997).
Deposits from continent-continent collision-related set-
tings (period of closing and intracontinental compression
and postcollisional period; Oligocene—Miocene). The clo-
sure of a branch of the Tethys Ocean along the Vardar-Izmir-
Central Anatolia Zone, starting in the Oligocene, was
followed by the collision between Africa and Europe, result-
ing in magmato-tectonic activity.
Ore deposits formed along the active continental margin
are related to intermediate magmatic rocks: dacites, quartz
latites, andesites and analogue plutonites of volcano-intru-
sive complexes. Magmas are derived from the lowest levels
of up-domed continental crust, but during upward move-
ment, they can be contaminated by some elements from gab-
bro-peridotite complexes (Cu, Au), or some lithophile
elements from the continental crust (Sn, W, Nb, Ta). In
comparison with the volcanic rocks developed in the sub-
duction-related setting of the eastern Serbian part of the Car-
patho-Balkanides, the Tertiary volcanic rocks in this tectonic
setting are characterized by an increased content of lead and
zinc, and by a diminished content of copper.
The principal ore deposits in Serbia associated with this
geotectonic condition (in the territory of the Vardar Zone
and the Serbo-Macedonian Massif) occur as skarn-type to
hydrothermal deposits related to volcano-intrusive complex-
es – hydrothermal metasomatic and veins, locally porphy-
ry-Cu and stockwork-disseminated Mo-types. The dominant
metals in these deposits are Pb-Zn, Sb, Bi, Ag, As. Copper
and gold occur only occasionally.
Ore elements were leached from host rocks by fluids from
the subcrustal magmas of I-type, strongly contaminated by
the crustal material and mixed with the heated descending
solutions.
Apart from magmatogenic ore deposits, some other miner-
al deposits have been identified in the collision-related envi-
ronment in Serbia (Janković et al. 2003). They are hosted by
the Miocene basins (magnesite, occurrences of boron, salt,
various types of clay, etc.).
The fossil fuels deposits are associated with the regions in
which there existed favourable conditions for the accumula-
tion and preservation of organic matter, particularly during
the Tertiary. The most important of these are the Pannonian
Basin and the smaller Tertiary basins of Serbia, in which pe-
troleum source rocks, oil shale and coal, were deposited dur-
ing the Miocene.
Mineral deposits
There are more then 2500 metallic and industrial mineral
deposits and mineral occurrences in the territory of Serbia
(Janković et al. 2003). Brief metallogenic features of the se-
lected deposits are presented in Table 1.
The present state and potential of the mineral
resources of Serbia
Many deposits of metallic and industrial mineral resources
of Serbia were still exploited until as late as the end of the
twentieth century. Today, however, the mining production,
particularly that of the metallic ores, has been either aban-
doned (Fe, Cr, Mn, W, Sb, Ni and others) or greatly reduced
(Pb-Zn, Cu, Au, Ag). This is a consequence of the intensive
exploitation of the better-quality ore reserves in order to re-
duce the production costs, of the exhaustion of economic re-
serves of Cr, Mn, W and other ores, as well as of the
considerable reduction of geological exploration. The base
metals (Cu, Pb-Zn), partly Al, Ni and some others, have been
more thoroughly explored and their total resources have been
augmented, so that they still represent, in spite of numerous
problems attending their exploitation, developmental potential
for Serbia. Many of the industrial mineral resources have shared
the fate of the metallic ores, but their ore reserves have been
considerably increased and they have gained in importance.
The production of fossil fuels – coal and, particularly oil
and gas, has been declining for the past 15—20 years, while
the valorization of oil shales as a non-conventional source of
oil requires a detailed analysis of the technological, econom-
ic and ecological factors involved.
Bearing in mind the above facts, the economically most
important mineral deposits of Serbia may be grouped as fol-
lows:

MINERAL RESOURCES OF SERBIA
1. Mineral resources which are already exploited and are
already provided with processing capacities (Cu, Pb-Zn),
and which continue to be the basis of the industrial develop-
ment of the country. This group of metallic mineral resources
includes the deposits of copper in the Bor Zone, the deposits
of Pb-Zn in the metallogenic zones of Kopaonik, Šumadija,
Lece, Besna Kobila and the Podrinje. The basic characteris-
tics of these deposits are a predominantly low metal content
and substantial ore potential. This group also includes indus-
trial mineral resources with a large, unused potential, such as
quartz sand, and mineral resources with a significant, partly
exploited potential, such as fluorite, dolomite, magnesite, ce-
ment marl, building industry granulates (natural and
crushed) and various types of clay. The fossil fuels belong-
ing to this group are coal, oil and gas.
2. Mineral resources with identified, economically inter-
esting, predominantly small reserves which are not already
exploited, and mineral resources occurring in small quanti-
ties, sufficient for brief periods of production and the supply
of domestic requirements. This group includes Sn, Mn, U, Mo
and Ti. The industrial mineral resources belonging to this
group are borates, feldspar, barite, asbestos and zeolites.
3. Potentially significant mineral resources with partly de-
fined ore reserves, the valorization of which depends on techni-
cal and economic parameters, as well as the partly explored
mineral resources with favourable prospects for reserve in-
crease. They include Ni, Co, Sb, Al, and mixed Fe-ores. Au, Ag,
salt, phosphorites, and wollastonite also belong to this group.
Although most of these resources are only partly explored, the
study of the geological setting and metallogenic processes of
Serbia show that there are favourable prospects for the discov-
ery of new resources. Oil shales also belong to this group.
4. Mineral resources likely to be found in the territory of
Serbia (Au, Ag, precious and disseminated metals). The met-
allogenic analyses carried out so far show that new resources
of gold are likely to be discovered in the Blagojev Kamen
area (hydrothermal quartz-vein type in the Neresnica-Beljan-
ica metallogenic zone), the Timok volcanic complex (por-
phyry copper-gold and epithermal gold deposits in the Bor
metallogenic zone) and Lece volcanic complex (high and
low sulphidation epithermal gold mineralization) the Lece-
Halkidiki metallogenic zone) and in some other areas. Silver,
gold and rare elements are mainly associated with the sul-
phide deposits of Pb-Zn and Cu.
5. Mostly exhausted or non-economic mineral resources.
They include Cr, Fe (suitable for the technology of blast fur-
naces) and W. Prospects for the discovery of new, economi-
cally significant resources are small.
Metallic mineral resources
The most important metallic mineral resources of Serbia
are non-ferrous metals and precious metals, ferroalloy met-
als, partly minor and related non-metals and fissionable met-
als. Especially important, as regards resource potential and
economic importance, are the deposits of copper and lead-
zinc, with the accompanying elements of association.
The measured, indicated, inferred and potential resources of
the main metallic ores are presented in Table 2.
The non-ferrous metals and precious metals are the eco-
nomically important group of metallic mineral resources of
Serbia. The most important are: Cu, Pb-Zn, Au and Ag.
Copper. The most important copper ores are located in: 1 –
the Bor metallogenic zone of the Carpatho-Balkanian metallo-
genic province (porphyry copper deposits Borska Reka, Veliki
Krivelj and Majdanpek), 2 – the Lajkovača ore district (hydro-
thermal volcano-sedimentary massive sulphide deposits) – one
of ophiolitic mélange, and, partly, 3 – in the Lece-Halkidiki
metallogenic zone (Kiseljak porphyry copper deposit: Mudrinić
& Seke 1997). Almost all the economic reserves of copper are
associated with the Bor metallogenic zone.
The metallogenic analyses carried out so far in Serbia have
indicated the areas with geological features which show that
they are likely to contain new Cu-deposits, predominantly of a
porphyry type (the Bor metallogenic zone), and, to a lesser ex-
tent, of a volcanogenic massive sulphide ore types (Lajko-
vača ore district). Gold and other elements of ore association
occur either together with copper or separately. The potentials
of gold are great. The potential ore-bearing areas have been
defined (Bor metallogenic zone and Lece-Halkidiki metallo-
genic zone); the control factors of the spatial position and the
conditions of origin of individual deposits of gold have been
established (Jelenković 1998).
Lead and zinc. The Pb-Zn deposits of Serbia are numerous
and economically significant. The greatest number of them
are in Kosovo. The potential resources are also substantial
and are located in the vicinity of known deposits – Blago-
dat, Lece, Veliki Majdan, Stari Trg, and in environments
with favourable metallogenic conditions – predominantly
in the region of calc-alkaline, volcano-intrusive complexes

of Neogene age in the Serbo-Macedonian metallogenic prov-
ince (Janković et al. 2003).
The conversion of measured, indicated and inferred lead-
zinc mineral resources (or a part of them), into proven and
probable ore reserves requires time and preliminary explora-
tions. An important problem in the valorization of these ores
is connected with the high mining loss during excavation
and low flotation recovery.
Tin. The resources of tin are small and cannot meet domes-
tic demand over a longer period. Tin is found in greissen and
alluvial deposits. The primary Sn-occurrences are not eco-
nomically interesting because of the small resources and low
content, while the placer deposits are on the verge of profit-
ability. It should be pointed out, however, that not much at-
tention has been devoted to the prospecting of the
Sn-deposits in the past.
Aluminium. The deposits of bauxite are of small economic
significance. They are of limited extent and poor quality.
The resources of iron and ferroalloy metals (Fe, Mn, Cr,
Ni, Co, Mo, and W) are rather limited and do not meet the
requirements of the domestic metallurgy.
Iron. The economically most important iron ores are: 1 –
The easy meltable limonitic ores from Majdanpek deposit.
2 – The magnetite ores from: a – skarn deposits, b –
metamorphic deposits and c – magnetite in porphyry coo-
per deposits. 3 – The complex oxide-carbonate-silicate ores
of the volcano-sedimentary type. 4 – Lateritic and redepos-
ited lateritic Fe-Ni-Cr ores. The mineral potential of the re-
deposited Fe-Ni-Cr ores is great, but they have not been
sufficiently explored from the metallurgically point of view.
Manganese. The most important manganese ores in Serbia
are: 1 – the oxide and silico-manganese ores from the volcan-
ogenic-sedimentary deposits which originated in association
with ophiolitic mélange or, less frequently, porphyrite-chert
formation of Middle Triassic age, and 2 – the Fe-Mn carbon-
ate ores. The former type was exploited in the past, but at
present there are no known ore reserves any more. The poten-
tial environments for the discovery of new deposits of silica-
manganese ores are the Priboj-Tutin Zone and the Rzav Zone.
Another area is Šumadija, with ores whose technological char-
acteristics have not been fully explored yet, and which are
supposed to contain ~ 0.1 Mt Mn. The determination of the
mineral potential of manganese in Serbia requires systematic
geological explorations and technological analyses.
The Fe-Mn carbonate ores of manganese in Serbia origi-
nated in association with the sulphide Pb-Zn deposits in the
Kopaonik metallogenic zone: Stari Trg deposits etc. They
have not been much exploited in domestic metallurgy in the
past, although they contain iron in addition to carbonates.
Nickel and cobalt. The Ni-Co deposits of Serbia are asso-
ciated with the lateritic zones of serpentinites of Kosovo and
within the Rudjinci-Veluće Zone. More thorough explora-
tions are necessary, however, for a valorization of the ore.
Molybdenum. The largest hydrothermal stockwork-dis-
seminated molybdenum deposit in Serbia is Mačkatica
(Simić 1997). Several occurrences of molybdenum have
been found in the Besna Kobila metallogenic zone, but no
full geological and economic estimate of them has been
made so far. Only preliminary explorations have been made
in the case of the other occurrences (the contact zones of the
granitoides of the Podrinje ore district, Kopaonik metallo-
genic zone, and the Mo-mineralization in the Majdanpek
porphyry copper deposit).
Tungsten. The resources of tungsten are small. It is mainly
concentrated in quartz veins (shellite). The areas of potential
interest for the prospecting of tungsten are the zones of
Blagojev Kamen, Golija and Kopaonik. It is possible that fu-
ture explorations will lead to the discovery of occurrences of
shellites in skarns, the economic significance of which is im-
possible to predict.
The resources of minor metals and related non-metals
(Sb, As, Be, Bi, Cd, Hg, REE, Se, Ta, Te, Ti, Zr etc.) are not
of economic importance is Serbia. The most important of
them are antimony deposits.
Antimony. In addition to several mines, Serbia has consid-
erable facilities for ore processing at Zajača with an installed
capacity of up to 4000 t Sb per year. More than 100,000 t of
Sb ore was excavated in this area between 1880 and 1991.
Conversion of antimony mineral resources to the ore re-
serves requires heavy investments in exploration (Janković
& Jelenković 1997).
Fissionable metals. The most significant concentrations
of uranium in the territory of Serbia are associated with the
granitoide complexes of Hercynian age (Mezdreja deposit),
Tertiary age (Paun Stena deposit), sedimentary series of Per-
mian age (Dojkinci deposit) and Neogene basins in the
fringe zones of granitoides. Uranium deposits associated
with granitoid complexes belong to the group of hydrother-
mal vein and stockwork deposits located in the fault zones,
while uranium deposits related to sedimentary series belong
to the group of ore of roll-front type of mineralization (Jelen-
ković et al. 1997). The further exploration of the uranium re-
sources will depend on the strategic decision of the state to
use them as the raw material for the production of energy.
Industrial mineral resources
There are more than 2000 deposits and occurrences of in-
dustrial minerals in Serbia. Several of them are already ex-
ploited (predominantly raw materials for the production of
construction materials). Seen from the economic point of
view, they can be classed as follows: 1 – Industrial minerals
and rocks already exploited (building construction industry
granulates and decorative stone, barite, dolomite, kaoline,
common clay, feldspars, white bauxite, zeolites, bentonite,
cement marl, ceramic and refractory clay, natural mineral
pigments, expanding clay, limestone, gypsum, diatomite,
petrurgical rocks, magnesite, siliceous rocks/quartz sand,
quartzite, opal, fluorite); 2 – Industrial minerals whose re-
sources and quality are determined, but which were not ex-
ploited in the past (boron minerals); 3 – Industrial minerals
and rocks with conditionally economic reserves (phosphates,
wollastonite, alunite, alumosilicates, vermiculite, garnets,
pyrophylite); and 4 – minerals likely to be found in Serbia
(salt and mica).
The most important industrial minerals of Serbia are: ben-
tonite, boron minerals, refractory clay, gypsum, diatomite,
dolomite, zeolite, kaoline, quartz sand, cement marl, ceramic

MINERAL RESOURCES OF SERBIA
clay, limestone, magnesite, phosphates, chrysotile-asbestos,
building industry granulates and decorative stone.
The measured, indicated, inferred and potential resources
of the industrial minerals of Serbia are presented in Table 3.
Bentonite. Large resources of high-quality bentonite clays
are located in several Neogene basins, but the mining pro-
duction of this mineral is below its natural potentials. A large
share of the resources has been classed as inferred because of
the unfavourable conditions of exploitation, poor quality of
the ore, problems of the processing technology or undefined
technical and economic conditions of exploitation.
Boron. The deposits of boron are located in the Ibar Neo-
gene Basin. The areas with potential new deposits are the
Vranje, Valjevo and other Neogene basins of Serbia.
Clays. A number of deposits of refractory, kaolinite and ce-
ramic clay are known in Serbia. Most of the deposits of the
best-quality refractory clay are either exhausted or nearing the
end of exploitation. The other refractory clays are of a poor to
medium quality, while the high-quality clays (with > 40 %
Al
2
O
3
and SK > 34) are imported. The deposits are predomi-
nantly of an allochthonous-sedimentary type, formed in envi-
ronments rich in humus in the fringe areas of Neogene basins.
The areas likely to contain deposits of clay are the basins of
Arandjelovac, Mladenovac and the Kolubara, as well as the
Liassic basins in south-eastern Serbia.
The available resources of kaoline are not of a particularly
good quality, but they are sufficient to meet the requirements
of the country.
The deposits of ceramic clay are mostly situated in the
Neogene basins of central Serbia and in the Liassic sedi-
ments of eastern Serbia. They belong to the high-quality clay
deposits of the illite-kaolinite type. Ceramic clay is exploited
from the deposits of the Posavina-Tamnava, Mladenovac
and Arandjelovac Basins. The available resources of ceramic
clay are sufficient to meet the requirements of the domestic
industry.
Gypsum. One sedimentary deposit of gypsum is known in
Serbia (Lipnica in Gruža). Gypsum is used only in the pro-
duction of cement. The present production is not sufficient to
meet the requirements of the other branches of the economy.
Diatomite. The deposits of diatomite are located in the
Neogene basins of Serbia. The most important of them are in
the Kolubara Basin and in the Metohija Basin. The proven
reserves of diatomite are 0.48 Mt with 60—77 % SiO
2
and
8—12 % Al
2
O
3
. Generally speaking, the mineral resources of
diatomite in Serbia are considerable, but only partly ex-
plored (particularly those in the Metohija Basin).
Dolomite. Serbia has significant resources of dolomite as
well as numerous dolomitic formations, which probably con-
tain still undiscovered deposits. Not counting the dolomite
used as building stone, the most important sources of this
mineral raw material are used in the glass industry, the pro-
duction of Mg-metal, refractory industry, metallurgy, etc.
Zeolites. The explorations of zeolites in the Neogene ba-
sins of Serbia have been in progress for more that twenty
years (Vranje and other basins). It is considered that new de-
posits may be discovered in many basins with volcano-sedi-
mentary series with laminated tuff, particularly if they are of
dacite composition.
Quartz sand and siliceous rocks. The deposits of industrial
quartz sand are numerous in the sediments of Serbia. They
are of varying quality and granulometry. It is possible to im-
prove the quality of the concentrate by the application of
modern methods of ore processing, which means that a sub-
stantial portion of resources can transferred to the ore re-
serves. Viewed as a whole, the geological resources of
quartz sand exceed the requirements of domestic consumers.
There are other mineral resources in Serbia, apart from
quartz sand, with silica as their basic component: vein quartz,
quartzite, cherts, or opal silica and quartz sandstone. Serbia’s
geological and economic potential as regards the quartz min-
erals has not been defined yet from the point of view of the
processing technology. The extent and quality of the identified
masses of quartz minerals show that there are reasons for the
construction of new industrial capacities, or the expansion of
old ones, for the production of ferrosilica, Si-metals and other
products.
Limestone and marble are found in extensive deposits in
Serbia. They mostly form deposits of sedimentary (limestone)
and metamorphic (marble) types, and sporadic vein deposits
of calcite also occur. Although limestone forms large geologi-
cal formations, its deposits are defined as specific parts of
these masses. The reserves of carbonate rocks for the require-
ments of metallurgy, chemical industry, production of sugar,
glass, paper, rubber, dyes, agrarian complex, etc. (not count-
ing the limestone used as building industry granulates)
amount to about 100 Mt.
Magnesite is a mineral with an important use in the refractory
industry of Serbia. It is associated with the weathered peridotite
complexes and Neogene basins of the Serbo-Macedonian prov-
ince. The ore is of a good quality, represented by crypto- to mi-
crocrystal magnesites with a high MgO content, relatively low
SiO
2,
CaO and good physico-mechanical characteristics. Depos-
its of crystalline magnesite, which are of great economic impor-
tance in the world, are not known in Serbia.

JELENKOVIĆ, KOSTIĆ, ŽIVOTIĆ and ERCEGOVAC
The most important deposits are in the area of Šumadija,
Beli Kamen and Goleš. About 80 % of the resources are in
vein deposits and 20 % are in sedimentary deposits.
Phosphates. One deposit of phosphates is known in Serbia—
Lisina. Although it is not being exploited because of technical
and economic reasons, it represents an important potential
source for the production of phosphorite concentrates.
Chrysotile-asbestos. The deposits of chrysotile-asbestos of
the fibrous ore type are located in the region of the Kopaonik
Zone.
Deposits of building construction industry granulates
(magmatic, sedimentary and metamorphic rocks) are very
numerous in Serbia (several hundred). As regards their quan-
tity and quality, they completely meet the requirements of
the domestic economy.
Fossil fuels resources
Serbia has significant resources of fossil fuels, particularly
coal and oil shale. Oil and gas reserves have been consider-
ably exhausted, but the calculated remaining potential shows
that modern exploration could lead to substantial new dis-
coveries.
Coal resources
There are 13 bituminous coal basins and 33 brown coal ba-
sins in Serbia. At present coal is exploited in 13 basins (2 bi-
tuminous coal and 11 brown coal basins). Some of the others
are exhausted, some are under exploration, and some have
been abandoned because of mining accidents. The geologi-
cal resources of brown coal in Serbia amount to 22.6 Gt, and
the economic reserves are 8.9 Gt. The geological resources
of bituminous coal amount to about 65 Mt, and the reserves
are 8.3 Mt. The greatest resources of coal (lignite) are in the
Kosovo, Kolubara, Kostolac and Metohija Basins, and in the
Kovin deposit (Fig. 3).
The brown coals of Serbia vary in their quality and degree
of carbonification (Ercegovac et al. 2006). They developed in
various clastic and terrigene lithostratigraphic units (from the
Lower to the Upper Miocene). Almost all the basins belong
to the intramontane lacustrine type. The only exceptions are
the coals of the Despotovac and, probably, Bogovina basin—
Istočno polje, which belong to the paralic type. Their rank
has been defined on the basis of the mean reflection of hu-
minite/vitrinite (0.26—0.50%), the total moisture content
(13.18—49.11%) and the net calorific value (21.2—28.1 MJ/
kg, dry, ash-free basis). Three groups of brown coals have
been defined on the basis of these parameters:
Soft brown coals (lignite, Low-Rank C; ECE-UN,
1998, 1999, 2000) are characterized by the huminite/vitrinite
reflection of 0.26—0.30 % R
r
; high content of total moisture
(43.41—49.11%); ash content, as-received basis of 17.40—
20.53 %; ash content of 31.6—42.91% (dry basis); total sul-
phur content of 1.06—3.98 % (dry basis); net calorific value
of 5.43—8.37 MJ/kg (as-received basis); net calorific value
(dry, ash-free basis) of 21.22—24.68 MJ/kg. These coals
have mildly acid to very acid ashes, with the melting point
values of 1261—1366
°C. The soft brown coals are pale
brown to dark brown in colour, and are of heterogeneous
composition with a predominance of matrix and xylitic litho-
types. The mineral-rich lithotype and doplerite coal appear
in very thin layers. The most common macerals are textinite,
ulminite, densinite and atrinite. Their vegetal structure is
well preserved, sometimes only slightly altered, and visible.
The liptinite and inertinite content is low.
Dull brown coals (Low-Rank B), are characterized by the
huminite/vitrinite reflection of 0.31—0.4% R
r
; total moisture
content of 17.05—37.59 %; ash content, as-received basis of
12.87—25.74 %; ash content, dry basis, of 18.82—34.57 %; to-
tal sulphur content 1.44—4.06 % (dry basis); net calorific value
of 10.51—16.97 MJ/kg (as-received basis); net calorific value,
dry, ash-free, of 24.3—26.6 MJ/kg. These coals have mildly
base to acid ashes, and the melting point varies from 1246 to
1318
°C. Dull brown coals are dark brown and often with
banded structure. The most common macerals of the coals of
this group are ulminite, textinite, densinite and atrinite. The

MINERAL RESOURCES OF SERBIA
liptinite content is comparatively low, except in some basins,
where it ranges from 10 % to 15 % (Lubnica Basin). The re-
sources of dull brown coals are comparatively large, but they
are of secondary economic significant because of their com-
plex tectonic and lithological composition and difficult condi-
tions for exploitation.
Bright brown coals (sub-bituminous, Low-Rank A), are
characterized by black colour, banded structure and highly
gelified tissue, with huminite/vitrinite reflectance between
0.41 and 0.47 % R
r
. They have total moisture content of
13.18—27.55 %; ash content, as-received basis of 12.54—
22.53 %; ash content, dry basis of 14.70—26.71%; total sul-
phur content of 1.35—6.54% (dry basis); net calorific value
of 13.35—19.45 MJ/kg (as-received basis); net calorific value
(ash-free, dry basis) of 25.26—28.05 MJ/kg; and mildly acid
ashes. The melting point varies from 1220 to 1393
°C. Most
common macerals are densinite, ulminite and gelinite. The
liptinite and inertinite content is low, except in the case of
the coal in the Aleksinac Basin, which has a high liptinite
content, and Bogovina-Istočno polje, which has a compara-
tively high inertinite content.
The bituminous coals of Serbia played an important role in
former Yugoslavia until the 1970s, but numerous mines have
been closed and abandoned. There are many explored, ex-
hausted and abandoned deposits of Carboniferous, Jurassic,
Cretaceous and Neogene basins. At present, bituminous coal
is mined only in the Ibar Basin and at Vrška Čuka. The bitu-
minous coals are divided into the following groups according
to the degree of carbonification:
Low-rank bituminous coals, with vitrinite reflection of
0.51—2.20 % R
r
, total moisture content below 10 %, volatile
matter content below 42 % (ash-free, dry basis), carbon con-
tent of over 75 % (ash-free, dry basis) and net calorific value
of 26—35 MJ/kg (ash-free, dry basis). The deposits belonging
to this group, which are being exploited, are located in the Ibar
Basin.
High-rank bituminous coals, anthracite, with mean
vitrinite reflection of over 2.20 % R
r
, total moisture content
below 5 %, volatile matter content below 10 %, carbon con-
tent of over 80 % (ash-free, dry basis) and net calorific value
of over 35 MJ/kg (ash-free, dry basis). The most important
deposit belonging to this group, and the only one being ex-
ploited, is at Vrška Čuka.
The future explorations of coal in Serbia will be aimed pri-
marily at the augmentation of the present reserves and a more
thorough analysis of their quality. It is also necessary to carry
out detailed geochemical analyses of the coal, coal ashes and
flying ashes in order to forecast and estimate the harmful and
potentially toxic elements. Only a comparatively small part of
the complex geological explorations will be devoted to the ex-
ploration of areas with prospective new coal deposits.
Oil and gas resources
The petroleum exploration carried out so far in Serbia
have resulted in the discovery of commercial accumulations
of oil and gas in the Pannonian Basin (the Banat Depression)
only. Minor occurrences of hydrocarbons have also been
found in some small Tertiary basins in Serbia.
Most of the hydrocarbon deposits are located in Miocene
clastic sediments, at depths of 400—3500 m. As many as two-
thirds of Serbian deposits are in the sands and sandstones of
the lower and upper Pontian, and a third are associated with
the earlier Miocene sediments and the basement (Paleozoic
schist and Mesozoic sediments). From the point of view of
proven reserves, the most important are the basal Miocene
sandstones and their basement (mainly fractured Paleozoic
schist).
More than 90 oil and gas discoveries, with more than 260
deposits, have been discovered in the Banat Depression,
which is still the most promising exploration area in Serbia.
There are 40 fields being exploited, and some are already ex-
hausted. The most important oil fields are “Velebit”, “Kikin-
da”, “Kikinda-varoš”, “Mokrin”, “Elemir” and “Turija sever”
(Fig. 4). About one third of oil is still produced in the field
“Velebit”, and “Kikinda-varoš” and “Kikinda” yield about
17 % each. “Turija sever” contributes about 14 % of the an-
nual production. As regards gas, the gas-oil field “Mokrin”
gives nearly a third of the annual production. The gas fields
“Srpska Crnja”, “Itebej” and “Srbobran” are also of consid-
erable importance.
The production of oil in Serbia began in 1956, and a total
of about 41 Mt has been produced so far. The quantities pro-
duced meet only 20—30 % of the domestic requirements. The
peak oil production was in 1982, when it amounted to over
1.3 Mt. That was followed by a general decline of produc-
tion. The production of gas began earlier, in 1952, and so far
about 28 billion m
3
have been produced. The greatest pro-
duction was in 1979, when it reached 1.1 billion m
3
.
The deposits of oil and gas in the Banat Depression are
primarily associated, as in most parts of the Pannonian Ba-
sin, with the elevated basement structures, so that the main
fields are in compaction anticlines and buried hills. The traps
are predominantly structural (convex and fault traps), less
frequently stratigraphic (pinch-outs and lances). Most depos-
its of the Banat Depression have paraffinic oil, but about
30 % of the reserves and production consist of biodegraded
naphthenic oil (“Velebit”, “Kelebija” and others with shal-
low reservoirs – at lower temperatures).
As regards the locations of petroleum deposits, it should
be pointed out that all accumulations discovered so far are
spatially closely related to the local depressions in which the
sediments are more than 2500—3000 m thick. The lateral mi-
grations of hydrocarbons are practically in all cases rather
short – 10 to 20 km. The structural geometry of depressions
strongly controls migration paths and hydrocarbon accumu-
lations in the Pannonian Basin, so most of them could be ac-
curately predicted (Kostić & Ercegovac 2002). The
directions of lateral migration paths are perpendicular to the
step-like normal faults, and, to a large extent, it took place
along the contact between the fractured basement and the
Tertiary clastites. The lateral migrations through later forma-
tions were also controlled by the faults and geometry of the
paleorelief.
The main oil source-rocks in the Banat Depression are
Pannonian and Sarmatian marly limestones and marls, then
Badenian shales and siltstone, and to a less extent Ottnan-
gian-Carpathian shale (Kostić 2000a). The sediments of the

MINERAL RESOURCES OF SERBIA
“lower Pontian” (local stratigraphic division), which contain
an unfavourable type of kerogen, represent source-rocks
only for gas, mostly in central and northern Banat, where
they are sufficiently matured.
As regards the further outlook of petroleum exploration in
the Serbian part of the Pannonian Basin, the application of
modern methods of exploration may be expected to lead to
new discoveries of oil and gas in the majority of the depres-
sions, although they are not likely to be very large fields. Re-
cent studies of the petroleum potential of the Banat
Depression show that highly rational and targeted explora-
tion may result in the discovery of an additional 20 % of the
initial reserves of oil and gas in Serbia (Kostić 2000b). There
are also good prospects for the condensate, small quantities
of which have been discovered so far, but which might be
expected at greater depths and in the deepest local depres-
sions. The most promising of the other areas for the explora-
tion of oil and gas in Serbia are the Srem Depression and the
small Tertiary basins of Serbia, although what is known of
them at present does not seem to indicate that substantial re-
serves may be expected.
Oil shale resources
Serbia has a considerable number of rather rich deposits of
oil shales, but not all of them have been thoroughly explored
(Ercegovac et al. 2003).
The genesis of oil shales in Serbia is associated with the
lacustrine depositional environments, which existed from the
end of the Late Cretaceous era, in the Paleogene and Miocene.
The major deposits of oil shales (Fig. 4) are in the Tertiary ba-
sins of Serbia and in a part of the Senonian tectonic trench in
eastern Serbia.
The oil shales of Serbia are typically lamosite, of Tertiary
origin, with the domination of kerogen types I and II. General-
ly they have kerogen content below 5 %, maturity levels that
correspond to huminite/vitrinite reflection up to 0.45 % R
r
and oil yield below 5 %. The total estimated oil shales re-
sources of Serbia amount to about 5 billion tons.
The largest and most important deposit of oil shales in Ser-
bia—Aleksinac – has considerably better characteristics than
the average deposits. It covers an area of 20 km
2
and it has two
thick productive sequences. The upper sequence of oil shale is
75 m thick and yields 10 mas. % of oil, on average. Lower se-
quence of oil shale is 26 m thick and yields 12.5 mas. % of oil,
on average. The potential reserves of oil shales in the Aleksinac
deposit are estimated at about 2.1 billion tons. Test production
of oil from Aleksinac shale yielded 80—90 l/t; 400 m
3
of gas/t,
and the potential in-place shale oil of this deposit are estimated
at about 210 Mt (Ercegovac et al. 2003).
The current study of the use of oil shales for the production
of synthetic oil will take into consideration all the relevant
technological, economic and ecological factors.
Conclusion
The end of the twentieth century and the beginning of the
twenty-first century marked a period of substantial decline of
mining production in many deposits of metallic and industrial
mineral resources of Serbia. This is a consequence of several
factors, the most important being: 1 – intense exploitation of
higher-quality ores: 2 – substantial reduction of geological
exploration; and 3 – inadequate investments in the develop-
ment of new technologies for the preparation and processing
of mineral resources which would enable the valorization of
lower quality ores as well.
The further development of the mineral resources of Ser-
bia depends on the mineral policy of the country, the strate-
gic decisions concerning future investment of domestic and
foreign capital into systematic geological exploration of de-
posits and prospective terrains, the development and intro-
duction of new technological methods of ore processing, the
adaptation of the existing procedures of ore processing to the
newly discovered deposits of mineral resources and the in-
creased profitability of exploitation.
The most important group of metallic mineral resources of
Serbia includes Cu, Pb-Zn, Au, Ag, and, to a considerably
lesser extent, Sn, Mn, U, Mo, Ti, W, Co, Sb and Fe ores. In
future explorations greater attention should be given to the
Cu and Au deposits in the region of the Bor metallogenic
zone; to the Pb-Zn deposits (Au-Ag with the accompanying
elements) in the region of the Serbo-Macedonian province;
and to the deposits of alloyed metals. The exploration of ura-
nium ores will depend on the strategy of the state concerning
the utilization of energy resources.
As regards the industrial minerals, of particular interest are
the deposits of bentonite, borate, refractory and ceramic
clays, gypsum, anhydrite, diatomite, industrial carbonates,
zeolites, quartz and quartz sands, magnesite, feldspars and
phosphates. Of the sporadically exploited or not exploited
industrial minerals particularly important are dunite and rock
for pottery and glass.
The soft brown coals represent the main source for the pro-
duction of electric energy, and they are therefore of great
economic importance. They will represent the mineral base
for the existing thermoelectric plants in the future, too, pro-
vided the prospective parts of the basins are additionally ex-
plored. There are considerable resources of bright brown
coals, but, owing to the complex tectonic features of their
basins and the difficulties involved in their production, they
are used only for general consumption and, occasionally, as
supplementary fuel in thermoelectric plants.
As regards oil and gas, recent studies show that more ratio-
nal exploration may lead to the discovery of additional re-
serves of oil and gas in Serbia, particularly in the Pannonian
Basin. As regards the remaining oil potential, the most prom-
ising are certain local depressions in the Banat Depression. Oil
shales also have a considerable potential, particularly the Ale-
ksinac deposit, but the exploitation of these non-conventional
oil sources depends on various technological, economic and
ecological factors.
