Abstract: The Tribeč granitic core (Tatric Superunit, Western Carpathians, Slovakia) is formed by Devonian/Lower
Carboniferous, calc-alkaline I- and S-type granitic rocks and their altered equivalents, which provide a rare opportunity
to study the Variscan magmatic, post-magmatic and tectonic evolution. The calculated P-T-X path of I-type granitic
rocks, based on Fe-Ti oxides, hornblende, titanite and mica-bearing equilibria, illustrates changes in redox evolution.
There is a transition from magmatic stage at T ca. 800—850 °C and moderate oxygen fugacity (FMQ buffer) to an oxida-
tion event at 600 °C between HM and NNO up to the oxidation peak at 480 °C and HM buffer, to the final reduction at
ca. 470 °C at
∆NN=3.3. Thus, the post-magmatic Variscan history recorded in I-type tonalites shows at early stage
pronounced oxidation and low temperature shift back to reduction. The S-type granites originated at temperature
700—750 °C at lower water activity and temperature. The P-T conditions of mineral reactions in altered granitoids at
Variscan time (both I and S-types) correspond to greenschist facies involving formation of secondary biotite. The
Tribeč granite pluton recently shows horizontal and vertical zoning: from the west side toward the east S-type grano-
diorites replace I-type tonalites and these medium/coarse-grained granitoids are vertically overlain by their altered
equivalents in greenschist facies. Along the Tribeč mountain ridge, younger undeformed leucocratic granite dykes in
age 342 ± 4.4 Ma cut these metasomatically altered granitic rocks and thus post-date the alteration process. The overlaying
sheet of the altered granites is in a low-angle superposition on undeformed granitoids and forms “a granite duplex”
within Alpine Tatric Superunit, which resulted from a syn-collisional Variscan thrusting event and melt formation ~ 340 Ma.
The process of alteration may have been responsible for shifting the oxidation trend to the observed partial reduction.
Key words: I- and S-type granitic rocks, granite duplex, Tribeč Mts, Western Carpathians, monazite, xenotime, titanite,

Introduction
Recent isotopic zircon and monazite datings enable the
subdivision of pre-Alpine granitic rocks from the Western
Carpathians into the following three principal groups:
(1) Devonian/Carboniferous orogen- and volcanic-arc-related
I-and S-type granite suites (Kohút et al. 2009; Broska et al.
2013; Uher et al. 2014), (2) Permian A-type granite suite
(Finger et al. 2003) and (3) Permian specialized [F-B-(Li)-(P)]
S-type granites (Uher & Broska 1996; Kohút & Stein 2005).
The main Alpine architecture of the Inner Western Carpathians
comprises three basement-involved Superunits – Tatricum,
Veporicum and Gemericum (e.g. Bezák et al. 2004). The I-,
S- type granitic rocks as part of the crystalline basement oc-
cur in the lowermost Tatric and middle Veporic Superunits,
the A-type granites are in the Veporicum while the special-
ized S-type are known only from the Gemeric Superunit.
The Tatric Superunit as a Paleozoic/Mesozoic crustal sheet
is composed of crystalline rocks (granitic rocks, low to high-
grade metapelites/metapsammites, and amphibolites) and sed-
imentary cover with prevailing Mesozoic carbonate rocks (e.g.
Maher 1986; Plašienka et al. 1997; Plašienka 1999; Bielik et
al. 2004; Bezák et al. 2011a). According to seismic data, the
Tatric Superunit is a tabular body about 10 km thick (Tomek
1993) rooted under the Veporic Superunit, the basement of
which is formed by similar Paleozoic and Mesozoic litholo-
gies. Seismic reflection profiles (Vozár & Šantavý 1999) as
well as magnetotelluric modelling in the Tribeč Mts (Bezák et
al. 2011b) point to the stacking and shortening of the crystal-
line basement within the Tatric Superunit especially in the
western part of the Western Carpathians.
The I-type granitic rocks in both the Tatric and Veporic
Superunits are mainly meta- to sub-aluminous granitoids, the
S-type are peraluminous, reflecting their respective different
sources (e.g. Petrík 2000; Broska & Uher 2001). The suites
of I- and S-type granitoids are not only products of contrast-
ing protoliths, but also of variable mantle input to their pri-
mary melts. An increased proportion of the mantle input
presumed for I-type granitoids is based on
143
Nd/
144
Nd ratios
(Kohút et al. 1999; Petrík 2000).
The duration of Variscan West-Carpathian granite-forming
events from subduction-related granitoids with volcanic arc
signature to post-Variscan, rift-related A-type granites and re-
lated Permian to Triassic volcanics (Finger et al. 2003; Bezák
et al. 2008; Demko & Hraško 2013; Ondrejka et al. 2015)
shows a time gap of ca. 60—100 Ma. Such a long time span

without magmatic activity in the Variscan terrain is apparently
improbable. During the Variscan orogenesis the Central Euro-
pean region has been intruded by numerous granitic intru-
sions, but some of them are missing in the Western Carpathians
(e.g. high K-types) or they occur in minor proportions.
The main goal of the paper is to present new geochrono-
logical and petrological data from Variscan granitic rocks of
the Tribeč Mountains, Western Carpathians, indicating a
syncollisional crustal nappe stacking event (granite duplex)
in the framework of the Variscan tectonic structure of the
Western Carpathians. Our recent field data from the Tribeč
granite pluton confirm earlier observations from the last
mapping by Ivanička et al. (1998a,b), which indicates a flat
position of altered (partly mylonitic) granite on coarse-
grained granitoids. In this sense, the position indicates the
existence of granite stacking or duplex within the Tribeč-Zo-
bor block. The principal arguments supporting this statement
are based on selected petrological data and the results of
monazite dating of geological profiles perpendicularly cross-
cutting the Tribeč Mts granitic rocks.
Geological background and sampling
The Tribeč Mts are formed by the south Tribeč-Zobor and
north Rázdiel part with different geological structures sepa-
rated by the Skýcov fault (Fig. 1). The crystalline basement
of the Tribeč and Zobor blocks are formed by the Tatric
Superunit, the north Rázdiel part by the Tatric and Veporic
Superunits (Ivanička et al. 1998a,b). The cover Mesozoic
complexes of the Tatric in the Tribeč part are formed mainly
by the Lužná Formation which contains a notable Alpine min-

eralization represented by primary and secondary phosphates
(lazulite, gorceixite, goyazite, goedkenite and other minerals;
Uher et al. 2009). The first mapping of Variscan granitoids of
the Tribeč-Zobor block in scale 1 : 50,000 (Krist 1960; Biely et
al. 1974) shows a large granodiorite pluton with leucocratic
granite rim on its northern and eastern edge. The latest geolog-
ical map in the same scale suggests a more heterogeneous and
zoned structure of the Tribeč-Zobor granite pluton (Ivanička
et al. 1998a). According to the authors, the central part is com-
posed of coarse-grained granites, towards the margins are me-
dium-grained granites, and the extreme margin comprises
fine-grained granites. But this mapping showed also my-
lonitized altered granites contouring the map level lines of
ground above medium/coarse-grained granites (Ivanička et al.
1998a). However, our recent field work found fine-grained al-
tered granite along the central ridge zone and not the coarse-
grained rocks as proposed Ivanička et al. (1998b). Similarly,
the fine-grained altered granitoids positionally above coarse-
grained granites are described in the area of the summit Verký
Tribeč Hill by the drillhole (Madarás et al. 2004). The con-
touring of altered granites on unaltered was confirmed.
Both I-and S-type granites were recognized in the Tribeč
Mts (Broska et al. 2000) and I-type granites show different
magnetic orientation compared to S-type granitoids, indicat-
ing their intrusion in a different tectonic regime and time span
(Figs.1b, 2a,b; Broska & Gregor 1992). The fine-grained al-
tered granites (Fig. 2c), located along the axial ridge zone of
the Tribeč Mts, contain small cross-cutting veins of unde-
formed leucocratic granites (Fig. 2d) which post-date alter-
ation of Devonian/Carboniferous I- and S-type granitoids.

(Konečný et al. 2004; Petrík & Konečný 2009), which in-
volves the correction of single spot analysis data against five

Petrography and mineralogy
I-type granitoids are typically calc-alkaline, coarse- to me-
dium-grained, meta- to subaluminous, biotite (leuco)-tonalites
to granodiorites. They contain euhedral to subhedral zoned
plagioclase (cores An
35—40
, rims An
20
) forming cumulates,
filled by interstitial potassium feldspar or quartz. Dark brown/
pale yellow biotite [Fe/(Fe + Mg) < 0.5, TiO
2
= 2—3 wt. %, MgO
ca. 12 wt. %, Al
2
O
3
ca. 15 wt. %] is very abundant, typically
enclosing common apatite, and accompanied by accessory eu-
hedral magnesiohornblende (ca. 1 vol. %). The Fe/(Fe + Mg)
ratio and TiO
2
contents in biotites effectively discriminate
between I-, S-type and altered granitoids (Fig. 3a, Table 1).
Small titanite grains are typically exsolved along biotite cleav-
ages and rims. The central parts of plagioclase crystals are to a
large degree replaced by saussuritic assemblage (albite, phen-
gitic muscovite, epidote), this retrogression being widespread
also in other rock types (enclaves, vein granites). The I-type
tonalite/granodiorite is rich in accessory minerals, which form
a typical oxidation assemblage of large magnetite grains, eu-
hedral titanite, abundant epidote and allanite. The late titanite
commonly encloses earlier small Ti-rich magnetite grains,
with outer envelopes of euhedral habit and zoned internal
structure (Fig. 4a,b). The late magnetite is very abundant,
forms large crystals of near pure end-member composition
with common pores and voids (Fig. 4b). It is invariably asso-
ciated with biotite and apatite. This rock type is characterized
by the occurrence of mafic magmatic enclaves (Petrík &
Broska 1989). Accessory amphibole shows typically magne-

(around 0.8) in comparison with magnesiohornblende due to
late oxidation. The TiO
2
contents decrease from 1.2 to zero
from magnesiohornblende to actinolite.
S-type granitoids are typically represented by medium- to
coarse-grained granodiorites/tonalites composed of domi-
nant, euhedral plagioclase (An < 45), strongly altered to fine-
crystalline mica aggregates (sericite) in central parts,
abundant, occasionally euhedral quartz, interstitial weakly
perthitic K-feldspar and large flakes of red-dark brown/pale
yellow biotite. Trioctahedral mica (biotite) in S-type grani-
toids is relatively Fe-rich with 19—22 wt. % FeO
tot
and MgO
7—10 wt. %, with Fe/(Fe + Mg) ratios between 0.55—0.65 (an-
nite, Table 1). They are typically also Al- and Ti-rich with
Al
2
O
3
16.5—17 wt. % and 3.5—5 wt. % TiO
2
, respectively.
Biotite is relatively fresh, locally chloritized, containing
abundant euhedral, large (0.4 mm across) fluorapatite crys-
tals commonly with zoned black cores. The accessory mineral
assemblage is different if compared to the I-type; besides ap-
atite and zircon, abundant euhedral monazite ( > 100 µm) is
enclosed within biotite where it forms pleochroic haloes,
moreover, small ilmenite grains are rarely found mostly
within biotite. Hornblende, allanite, magnetite and titanite
are absent in S-type granitic rocks of the Tribeč Mts.
Altered granite-forming mylonitic belts along the moun-
tain ridge are represented by retrogressed, occasionally de-
formed, fine-grained granitic rocks consisting of a completely
saussuritized mass and deformed, dynamically recrystallized
quartz. The saussuritic mass consists of fine-grained pheng-
ite, clinozoisite, albite occasionally with muscovite or biotite
flakes. Former biotite is replaced by chlorite and epidote. Ti-
tanite was found completely replaced by ilmenite by reduc-
ing fluids (T-121 sample). Domains of undeformed, weakly
perthitic and cross-hatched K-feldspar phenocrysts (porphy-
roblasts) may be preserved in the quartz-sericite matrix.
These phenocrysts are poikilitic enclosing unaltered biotite,
apatite, quartz and sericitized plagioclase. Large monazite
crystals occur in the groundmass (T-121) along with xeno-
time. Both minerals are retrogressed along rims forming epi-
dote-apatite coronas (Broska et al. 2005). In a sample of the
altered granite (T-33) Al-rich pumpellyite was found as part
of the saussuritic assemblage replacing plagioclase (with al-
bite, phengite, epidote; Fig. 5a, Table 2). Typical for the al-
tered granite is intergranular, newly formed tiny biotite
(Fig. 5b) and consumption of titanite by ilmenite (Fig. 4c).
Biotite with the same composition also appears within pla-
gioclase grains (see for example reaction (4), Table 4) possi-
bly in a different geotectonic event. The alkali feldspars from
altered Tribeč granitic rock contain relatively pure K-feldspar
(Kfs) with a maximum of 6 mol % Ab and less than
0.3 mol % An (Table 3). While the K-feldspar from S-type
granites is mostly interstitial in altered granites it forms indi-
vidual euhedral zoned grains up to 1 cm in size (Fig. 5c). A
profile across a grain indicates a typical bell shape Ba distri-
bution pointing to Ba fractionation during primary magmatic

evolution. The typical BaO concentration is
> 1 wt. % but locally it may exceed 2 wt. %
(Table 3).
Dioctahedral white mica from all granite
specimens in the Tribeč Mts types corre-
sponds to phengite (ferro-aluminoceladonite).
The phengite usually forms a dense network
of sheets on former plagioclases but com-
monly occurs also in interstitial positions. It
has variable Fe concentrations from 3.5 to
5 wt. % FeO
tot
(Table 2). The Fe shows hetero-
geneous distribution, with rims enriched in Fe.
The characterization of accessory phases
which includes zircon morphology, apatite
composition, the presence of monazite and xe-
notime along with K-feldspar and biotite com-
positions (low Ti contents), indicate mainly
S-type granite precursor of the altered granites.
The dated sample of tonalite (T-123) is
coarse-grained, formed by strongly saussuri-
tized plagioclase (An
21
in preserved parts) and
anhedral, undulatory quartz with subordinate
biotite, completely replaced by secondary
muscovite and goethite. K-feldspar is absent.
Vein granite (cutting retrogressed mylonitic
granites), is represented by a medium-
Titanite and Fe-Ti oxides
Titanite is a characteristic and common mineral of I-type
tonalites where it forms euhedral to subhedral, zoned crys-
tals. Corroded inclusions of an earlier, Ti-rich magnetite
(showing exsolutions of magnetite
ss
in ilmenite
ss
and vice
versa) in titanite centers suggest that it consumes and over-
grows these earlier Ti-rich phases (Fig. 4a,b, see the section
P-T-X conditions). The titanite outermost euhedral zone is
free of the Ti-rich magnetite remnants and probably formed
from Ti liberated from biotite (which has TiO
2
typically
< 3 wt. %). However, in many tonalite samples the titanite is
retrogressed back to ilmenite, which may completely replace
titanite, forming pseudomorphs (see fig. 3d in Broska et al.
2007). BSE bright zones of the titanite indicate enrichment
in rare earth elements (REE). Their distribution may be com-
plicated, but they typically form outer envelopes around the
earliest (Fig. 4a) REE-poor titanite originated from Ti-rich
magnetite (see reaction 1) at relatively high T. The REEs fol-

ing reducing environment (Table E3). In S-type granitoids, il-
menite is stable mineral instead of magnetite, suggesting a
primary reduced character of S-type granite protolith (T-122).
It is also found in altered granite rich in alkali feldspar and
poor in biotite. Ilmenite from this rock type is invariably re-
placed by mixture of Ti phases to titanite (Fig. 4d) forming
“leucoxene” grains with remnants of ilmenite in centers.

grained muscovite leucocratic granite. The dated leuco-
granite (T-132) is formed by sub- to euhedral, sercitized pla-
gioclase An
19—20
, anhedral undulatory quartz, perthititic
subhedral K-feldspar, abundant flaky muscovite (ca.
10 vol. %) and subordinate biotite ( < 5 vol. %), which may
be completely chloritized. Accessories include apatite, ore
minerals and small (ca. 20 µm in size) monazite grains en-
closed in biotite and plagioclase, commonly with thin allan-
ite coronas.
Typomorphism of accessory minerals
Zircon
The composition of zircon shows typical crustal character
(Zr/Hf
wt
= 0.42). The most distinct differences among the
studied granite types are seen in zircon morphological pa-
rameters. The zircons from S-type granodiorite in the Krnča
area show prevalence of morphological subtypes S
3
, S
7
and
S
8
(according to Pupin 1980). The zircon morphological ty-
pological mean point for sample T-18 is I.A = 338, I.T = 342.
The typical morphometric subtypes for the sample of
I-type tonalite (T-88) are S
12
, S
21
, and S
4
, while a younger
generation shows subtypes G
1
. The I-type granite typologi-
cal mean point can be characterized by following parame-
ters: I.A = 524 and I.T = 342.
The dyke cutting altered granites shows an S-type charac-
ter but different from the S-type (peraluminous) tonalite
from the Krnča area with I.A = 330, I.T = 250.
The altered granites from the Tribeč Mts ridge zone con-
tain zircon with low S and L morphological subtypes resem-
bling the zircon characteristics of S-type granites.

Magnetite occurs only in I-type tonalites as an early phase
consumed by titanite (Fig. 4a) where exsolution lamellae are
formed from Ti-rich magnetite mostly with 9—15 wt. %
TiO
2
. Reconstructed compositions of both ilmenite and mag-
netite solid solutions using wide electron beam and the oxy-
barometer of Ghiorso & Evans (2008) give 800—950 °C at
NNO buffer (see section P-T-X conditions). The other, com-
mon late stage large magnetite contains only 0—2 wt. % TiO
2
(an9, Table E3). It is usually intergrown with biotite, com-
mon voids were probably originally filled by fluids indicat-
ing the growth in the presence of fluid phase.
Apatite
Apatite is a good indicator of I and S-type granite rocks by
its Fe and Mn contents (Broska et al. 2012). Both cations in-
crease from I- to S-type. The apatites from I-type granitoids
in Tribeč contain 0.008 Mn apfu (0.11 wt. % MnO), S-type
0.017 Mn apfu (0.22 wt. % MnO). Apatite from altered gran-
ite shows higher Mn = 0.017 apfu.
A unique preserved rotation of apatite crystal in mica from
altered granite sample T-122 suggests a deformation event in
ductile conditions. The rotation of apatite is an important
record of the kinematic Variscan history of the altered gran-
ite (Fig. 5d, Table E4).
Allanite-(Ce), monazite-(Ce) and xenotime-(Y)
Allanite-(Ce) from I-type tonalites has a transitional compo-
sition (Petrík et al. 1995; Broska et al. 2012) among allanite,
ferriallanite and epidote end-members with Fe
3+
/Fe
tot
ratios
0.4—0.55 (Table E5). The highest oxidation is seen in late rim
domains and occurred in subsolidus conditions (stages 2, 3,
see section P-T-X conditions). Its REE distributions show an
invariably positive Eu anomaly. By contrast, a rare allanite
found as a relic within monazite in peraluminous, reduced
S-type granitoids (for example sample T-18) shows a different
composition, rich in Al and with variable f = Fe
3+
/Fe
tot
ratios
from strongly reduced to oxidated (f
≤ 0.55), Table E5.
Monazite-(Ce) is present in S-type granite rocks, leucocratic
dykes within I-type granitoids and in all altered granitoids. It
forms large zoned crystals with BSE brighter, Th-enriched (up
to 10 wt. % Th) zones. A Th-rich phase (huttonite—cheralite
mixture) was found within a large monazite (190 µm) of Al-
pine age (see Monazite dating section). All dated monazite
crystals show negative Eu anomalies, the most profound in
dyke leucogranite (Eu/Eu* = 0.25—0.03), least pronounced in
peraluminous granodiorite T-18 (0.6—0.1). The dyke also con-
tain several monazite grains with high U (0.3—0.8 wt. % UO
2
)
compared to other rock types with monazite containing
< 0.2 wt. % UO
2
. Monazite in the undeformed S-type granite
rocks is euhedral without any sign of alteration, whereas al-
tered granites commonly preserved monazite partially re-
placed by common thin allanite (epidote)—apatite coronas.
Xenotime-(Y) (Table E4), found in the altered type, has
mole fraction of YPO
4
0.75—0.77 which is within the range
of xenotimes from other S-type granitoids (Broska et al.
2012). Yttrium is accompanied mostly by Dy, Er and Yb
with X
(Y + HREE)
reaching 0.95—0.97. Monazite and xenotime
in the altered granites are strongly retrogressed, commonly
to well-known apatite—epidote coronas (Finger et al. 1998;
Broska et al. 2005). Monazite breaks down to LREE-rich ap-
atite and allanite, or LREE-rich epidote, while xenotime-(Y)
breaks down to Y-enriched apatite and epidote (Fig. 5e,f).
There is no compositional difference between unaltered xe-
notimes and remaining xenotime partially, replaced by epi-
dote coronas. Xenotime from dyke granite shows no signs of
alteration. Rarely, dark remnants of an old monazite were
found in a large 100 µm long monazite grain (see Monazite
dating section). Some monazite grains from vein type gran-
ites are extremely enriched in U (up to 3.2 wt. %, Table E6).
A large grain of ThSiO
4
phase was found in the altered
granite (T-122), with increased ZrO
2
(3 wt. %) and low LREE
indicating that it represents thorite rather than huttonite.
Monazite dating
Monazite frequently occurs in S-type, altered and dyke
granitoids from the Tribeč Mts. Since these rock types have
not been dated in this basement core so far our study pro-
vides the first geochronological data (source data in
Table E6). BSE images of selected dated monazites with
analysed points (see Table E6) are illustrated in Fig. 6.
S-type granitoids: The age is based on measurements of
monazites from two samples (T-18, T-220) from the Krnča
area (Fig. 1). Although monazites slightly differ in their
chemistry they provide an excellent common isochron Th*
vs. Pb (Fig. 7a). Individual ages from 5 monazite grains in
T-18 (21 analyses) and 4 monazite grains in T-220 (17 anal-
yses) are listed in Table E6. The isochron based on 33 points
(5 points with ages < 325 and > 400 Ma were excluded) yields
the weighted mean age of 352.4 ± 11.7 Ma (MSWD = 1.08,
intercept 0.0009). The weighted fit (2
σ errors) was calculated
by Isoplot 4.15 (Ludwig 2008).
Altered granite: Two samples of altered granite were dated,
T-121, 131. Both samples contain monazites characterized
by relatively homogeneous compositions with Th/Pb and U/Pb
ratios 55—65 and 0.7—3.2, respectively. A set of 29 points ex-
cluding 5 outlying points yields a well-defined, standard Th*
vs. Pb isochron with negligible intercept of +0.001 Pb (Fig. 7b).
The weighted fit (2
σ errors, calculated with Isoplot 4.15,
Ludwig 2008) yields the age of 358 ± 17 Ma. This age of the
altered granites is identical with S-type granodiorites and prob-
ably does not represent the age of low temperature alteration.
Dyke granite: A different age was obtained from the dyke
on the Medvedí vrch Hill, which cuts the same deformed
granitoid body as in the Malý Tribeč Hill. Monazites from
this rock type (samples T-123, 132) show the wide range of U
and Th concentrations including several grains with high U
(up to 3.2 wt. % UO
2
), resulting in ratios U/Pb from 20 to 60
and Th/Pb of 1—15, in contrast to monazites from mylonitized
granites with much more homogeneous compositions. Such
monazites are suitable for U/Pb vs. Th/Pb isochron method
of Cocherie & Albarède (2001). The ideally concordant iso-
chron yielded the centroid age of 342.2 ± 4.4 Ma indicating
that both U/Pb and Th/Pb systems remained closed (Fig. 7c,
Table E6). The age is younger than the age of altered granite

ting the altered rock (Fig. 2d).
Early Devonian ages: an old monazite remnant within a
large grain from the altered granite (T-123), yielded the age of
434 ± 54 Ma (Fig. 6a). Four other similar ages are from sam-
ples T-121, 220: 410 ± 35, 413 ± 29, 415 ± 35 and 436 ± 45 Ma.

Alpine ages: Young ages come from undeformed I-type
tonalite (T-18). A Th-rich phase (possibly a mixture of
huttonite and cheralite) occurring within large monazite
yielded age 81 ± 2.5 Ma. Several euhedral 50 µm grains
showed Alpine age record of 92 ± 31 and 86 ± 24 Ma in
sample T-25.

P-T-X
conditions in evolution of the I-type and
S-type granitoids
Earlier pressure estimates for ~ 365 Ma I-type tonalites
containing hornblende (Petrík & Broska 1994) were ob-
tained by Al-in hornblende geobarometry (Hollister et al.
1987), and constrained ca. 350 MPa of lithological pressure.
Slightly higher results are obtained using later calibrations.
In this work, the pressure was determined using the equa-
tion of Anderson & Smith (1995): P( ± 0.6 kbar) = 4.76 Al—
3.01—[(T(°C)—675)/85]*[0.530 Al + 0.005294(T(°C)—675)].
The hornblende composition is shown in Table 2. Al
tot
= 1.5
(per 23.5 O) using the above equation gives a curve, which at
near solidus temperature T = 560—620 °C indicates the pres-
sure P = 400—420 MPa.
Temperature and oxygen fugacity: Application of the Zr
saturation thermometry (Watson & Harrison 1983) to Tribeč
I-type tonalites, which contain magmatic zircons with negli-
gible inheritance (Broska et al. 2000), gives a range of temper-
atures 820—725 °C at 63—75 % SiO
2
, respectively. However,
the continuing re-equilibrations during late magmatic cool-
ing record temperatures down to 650 °C (based on the Fe-Ti
oxides analyses from Broska et al. 2007). Oxybaro-ther-
mometry based on the Fe-Ti oxides enclosed in titanite indi-
cates T = 800—850 °C at f
O2
of the FMQ buffer (Ghiorso &
Evans 2008), see (1) in Fig. 8d. These early Fe-Ti oxides are
replaced by reactions with Ca minerals producing new titan-
ite and annite, Fig. 4a (Broska et al. 2007), reaction ((1) not
shown), Table 4. The reaction is strongly dependent on H
2
O
activity: at a
H
2
O
= 0.5 gives T = 707 °C (P = 400 MPa) with T
increasing with increasing a
H
2
O
. (This and the following re-
actions were generated, and P-T-X conditions calculated us-
ing Thermocalc 3.31 (Holland & Powell 2011) and AX
software for end-member activities (Table 2)).
In I-type tonalites the late- to post-magmatic oxidation re-
sults in the formation of magnetite, biotite and horn-
blende + pure magnetite + titanite (reactions 2—4, Table 4)
accompanied by epidote, see intersection (2) in Fig. 8a. The
trend of increasing Mg# in actinolite (Fig. 3b) with cooling,
also indicating oxidation, was demonstrated by Blundy &
Holland (1990). The original assemblage, Ti-magnetite and
more Fe-rich biotite, was thus more reduced (Broska &
Petrík 2011), point (1) in Fig. 8d. The oxidation continues to
lower T involving phengite and producing even more mag-
netite and reaching the highest f
O2
( ~ HM buffer) (intersec-
tion (3) in Fig. 8b, reactions 3—7, Table 4). However, in the
Tribeč I-type tonalites the oxidation ceases on further cool-
ing, as is indicated by replacement of titanite by ilmenite
pseudomorphs. The reduction and hydration reactions pro-
duce ilmenite, clinozoisite, and epidote (reactions 8—13, Ta-
ble 4, intersection (4) in Fig. 8c).
The S-type granites do not contain mineral assemblages
that could be used for estimation of pressure, but saturation
temperatures of REE and T
Zr
thermometry are similar, even
higher than I-type tonalites (725—825 °C). The absence of
oxidation minerals (titanite, magnetite, epidote) coupled
with high Ti- and Fe-rich biotite suggest reducing condi-
tions. Indeed, it would seem that the main difference be-
tween Tribeč I-type and S-type granitoids was in their redox

of 342 ± 4.4 Ma. All regressions by weighted fit (Isoplot 4.15).

regime. However, other features: much more peraluminous
and more acid in nature (which is responsible for S-type
classification even in the absence of muscovite), and most
notably the presence of abundant monazite in the absence of
allanite, all indicate a different source of the peraluminous
granite magma. This also implies the differences in the REE
patterns (Broska & Uher 2001).
Discussion
Contrasting redox evolution
The rich primary and secondary mineral assemblages in
various granite types from the Tribeč Mts point to a long
magmatic and post-magmatic evolution. The calculated P-T-X
path of I-type tonalites, based on Fe-Ti oxides, hornblende,
titanite and mica-bearing equilibria, illustrates the transition
from a magmatic stage at T ca. 800—850 °C and moderate
oxygen fugacity (FMQ buffer) to an oxidation event at
600 °C between HM and NNO up to the oxidation peak at
480 °C at HM buffer, and the final reduction at ca. 470 °C
and
∆NN=3.3 (Fig. 8d). The reason for oxidation is seen in
the dissociation of exsolved water to H
2
and O
2
, and subse-
quent H
2
escape (Carmichael et al. 1974). S-type granites
(peraluminous but without primary muscovite) show an en-
tirely different evolution typically starting at relatively high
T = 825 °C preserving the original reduced nature without
post-magmatic oxidation. The low-T alteration involves sau-
ssuritization of plagioclase and ilmenite replacement by sec-
ondary phases (“leucoxene”). This is explained by a different
protolith composition, namely a lower content of water in
the magma or its escape after emplacement.

The altered granitoids
The altered granitoids were heavily retrogressed by hydra-
tion along a possible shear zone leaving only quartz and a
fine-crystalline muscovite (“sericite”) mass. Some reactions
(5—7) involve phases present in the altered granitoids
(phengite and biotite) and the derived T < 460 °C may pre-
sumably be applied to estimation of the conditions of dyna-
mo-metamorphic reworking of granitoids from the ridge part
of the Tribeč Mts. The post-magmatic, late Variscan or Al-
pine low grade metamorphism is supported by breakdown of
monazite and xenotime (Malý Tribeč Hill and Medvedí vrch
Hill). The monazite and xenotime break down to form
LREE-rich apatite and allanite coronas, Y-enriched apatite
and epidote, respectively (Fig. 5e,f), for details see Broska et
al. (2005). The experimental data on monazite alteration to
REE-epidote and fluorapatite (P = 450—610 MPa and T = 450
to 500 °C) showed the dependence of alteration products on
the character of fluids. A high Ca content in the fluid pro-
motes monazite dissolution and the formation of fluorapatite
and allanite or REE-epidote (Janots et al. 2008; Budzyń et al.
2011). Increasing Na activity in the fluid promotes formation
of apatite with increased britholite component, which is also
strictly related to Na + REE substitution in apatite (Budzyń et
al. 2011). Similarly to monazite, xenotime-(Y) breakdown is
controlled by pressure, temperature and fluid composition.
Some Y-HREE-rich apatite on xenotime-(Y) was experimen-
tally produced by a Ca rich fluid-mediated low temperature
(350 °C) regime at pressure 400 MPa (Budzyń & Kozub-
Budzyń 2015). Similar conditions can be expected in the for-
mation of xenotime-(Y) breakdown in the Tribeč Mts.
Syn-collisional granite
This monazite age of S-type granitoids in the Tribeč Mts is
identical with the monazite age of S-type granodiorites from
the Bratislava Massif, Malé Karpaty Mts (353 ± 2 Ma, Uher
et al. 2014) and 355 ± 5 Ma zircon SHRIMP age of the same
granitoids (Kohút et al. 2009). The S-type granitoids appear
younger than 358—367 Ma I-type tonalites (ion microprobe
zircon dating, Broska et al. 2013).
The age of monazites (ca. 340 Ma) from dyke cutting the
retrogressed (partly mylonitic) granites altered to greenschist
facies (Medvedí vrch Hill) for the first time documents the
existence of a younger granite-forming event in the Tribeč
Mts than the Devonian/Lower Carboniferous. This Visean age
is similar to the age of some Tatry Mts diorites 341 Ma (Poller
& Todt 2000) or granitoids in the Žiar Mts 338 Ma (Kohút
2015) indicating a younger magmatic activity also in other
parts of the Western Carpathians. This age is coeval with the
age of the main Variscan collisional event in the Europe and
corresponds to the second group of granites according to
model of Finger et al. (1997): (1) Late Devonian to early
Carboniferous I-type (370—340 Ma); (2) Early Carboniferous
syn-collisional S-type, ca. 340 Ma; (3) Late Visean—early
Namurian high K-type, 340—310 Ma; (4) Post-collisional
I-type, 310—290 Ma; (5) Late Carboniferous and Permian
mainly A-type, 300—250 Ma (alternatively see Timmerman
2008 or for a recent tectonic view Žák et al. 2014).
The significance of the 340 Ma event in the Western Car-
pathian realm is difficult to assess because its regional extent
in other mountain ranges is poorly known. However, new
monazite data suggest that this event may have been more
widespread. It marks the end of the main granite-forming
event in the Western Carpathians or the very beginning of the
extensive granite magmatism in the Bohemian massif corre-
sponding to isothermal decompression of the crust (Janoušek
& Gerdes 2003; Janoušek et al. 2004, 2010; Kotková et al.
2010; Žák et al. 2014). An important granite forming event
at 340 Ma is also known from the Tauern window (Eastern
Alps) following volcanic arc granitoid origin at 374 Ma
(Eichorn et al. 2000).
Other ages obtained: Early Devonian ages from relict
monazites are within error identical with the U-Pb single zir-
con core age (414 ± 8 Ma) obtained from nearby Tribeč I-type
tonalite (Broska et al. 2013) and indicate an Early Devonian
protolith of granitoids in the Tribeč Mts.
Two Alpine ages obtained, ca. 90 and ca. 80 Ma are slightly
older than the Alpine reworking in the Tribeč granitoids
(mylonite zones) documented by white mica
40
Ar/
39
Ar ages
71—63 Ma (Kráx et al. 2002). According to the scheme based
on fission track ages and proposed by Králiková et al. (2014)
the earlier age would correspond to a paleo-Alpine burial of
the Western Carpathian basement whereas the later one is re-
lated to its exhumation.
The Variscan thrusting and forming of “granite duplex”
The altered granites extensively developed along the
Tribeč ridge zone are, according to the geological map of
Ivanička et al. (1998a), flat-lying on undeformed granitoids
following roughly map contour lines. Such a position evokes
the low-angle superposition of two Variscan granitoid bodies
(Fig. 9). The leucocratic granite dyke cutting the altered
granite with the age of 342 Ma indicates the minimum age
not only of the alteration but also of this low-angle granite
stacking. Therefore, zircon and monazite datings and rock
field relations constrain the age of the alteration/deformation
event as Variscan ( > 342 Ma). The character of the event in-
vokes a massive, region-scale fluid ingression into the shear
zone in high water/rock ratio regime reaching various grani-
toid types including granites and tonalites.
Fig. 9. A proposal of the low-angle granite thrusting on profile
Krnča—Velčice. Corresponding datings of granite blocks indicate in-
tensive Variscan shortening during the collisional event and forma-
tion of the granite duplex. Injections of leucocratic granite veins
through the granite complex is known from mapping work of
Ivanička et al. (1998a). The southward direction of thrusting corre-
sponds to general Variscan thrusting directions (e.g. according to
Bezák et al. 1997).

The flat position of the fine-grained granitoids above
coarse-grained I-type tonalite was also confirmed by the
RAO-3 borehole in the depth of 100 m close to the Verký
Tribeč summit (Fig. 1a; Madarás et al. 2004). Low angle
thrusting within the Tatric Superunit is indicated by seismic
profiles (Vozár & Šantavý 1999) and interpretation of magne-
totelluric measurement in the Tribeč Mts (Bezák et al. 2011b).
The widespread fine-grained or altered granites lying on
coarse-grained I-type tonalite from the area of Verký Tribeč
Hill to Javorový vrch Hill evoke the extensive Variscan thrust
stacking occurring recently in the framework of the Alpine
Tatric Superunit. Based on the RAO-3 drill hole, a minimum
of 400 m thickness of the fine-grained granitoids is presumed
(Madarás et al. 2004). The Variscan stacking is known in the
Western Carpathians on a relatively large scale and the direc-
tion of the Variscan thrusting is generally towards the south
(e.g. Kahan 1969; Bezák et al. 1997; Janák & Plašienka 1999;
Hurai et al. 2000; Janák et al. 2001). The Variscan thrusting in
the Tribeč Mts is manifested by formation of granite duplex,
or stacking of altered on unaltered granites, originated during
the Visean. The Variscan middle-crustal thrusting was only
slightly later modified by Alpine tectonics and this scenario
could be widespread also in other parts of the Western Car-
pathians (Bezák et al. 2014).
Our idea resulting from the presented petrographic, miner-
alogical, petrological and geological data suggests that the
stacking of the granite bodies occurred before age 342 Ma,
and so before the emplacement of the leucocratic dyke
(Fig. 9). Both magmatic events (ca. 365—352 and 342 Ma) in
the Tribeč Mts terminated Variscan activity in the present
Tribeč Mts. The presumed age of thrusting is coeval with
syncollisional magmatism in Variscan Europe and could be
correlated with the collisional event producing an intensive
fluid activity within existing granite bodies (Weinberg &
Hasalová 2015).
Conclusions
The Late Devonian to early Carbonifeous orogen-related,
calc-alkaline I-type granitic suites in the Western Car-
pathians are markers of an early Variscan active margin. The
Tribeč Mts contain both I- and S-type granite bodies, which
originated during the early stages of Variscan subduction
(ca. 360 Ma). The contrasting post-magmatic evolution ex-
emplifies the role of water and oxygen fugacity in different
granite types (oxidation or lack of it) reflecting differences in
their source rocks including the water content.
The age of the altered (mylonitic) ridge zone, 359 ± 17 Ma,
encompasses the age of both I- and S-type magmas (Broska
et al. 2013) whereas the dyke granites cutting altered gran-
ites are significantly younger, ~ 340 Ma. This younger age in
the Tribeč Mts (Prototatricum in the sense of Broska et al.
2013) can be correlated with heating in the Variscides pro-
ducing granitoids in many places, such as the Bavarian phase
in the Moldanubian sector of the Bohemian Massif (Finger et
al. 2007), durbachites at 335—342 Ma (Finger et al. 2007;
Kusiak et al. 2010), or in the basement of the Eastern Alps
(orthogneisses 340—343 Ma, Eichorn et al. 2000). Monazite
dating also provided a presence of apparently restitic (clas-
tic) monazite cores ca. 420 Ma old. They represent possible
remnants of an Ordovician protolith of the Tribeč granitoid
magmas and correspond well to similar older monazites
from S-type granitoids of the Bratislava Massif (Malé Kar-
paty Mts, Uher et al. 2014).
In the Tribeč Mts, the weak ~ 340 Ma magmatic activity
probably reflects thrusting of the Prototatric unit accompa-
nied by increased fluid activity, which altered (retrogressed)
the granites to greenschist faces. Now they occur along the
ridge zone of the Tribeč Mts. The juxtaposition of two differ-
ent granitic blocks (the coarse-grained tonalite in the bottom
and the altered granite in the upper part) of Middle Missis-
sippian age indicates the tectonic complexity of the Tatric
Superunit on the one hand, and a spatial separation of the
Prototatricum (which lacks the voluminous ~ 340 Ma mag-
matism) from the Saxo-Danubian Granite Belt in the
Variscan realm on the other.
The altered S- and I-type granites from the axial zone of
the Tribeč Mts at present look fine-grained due to extensive
retrogression. In this manner, the Tribeč granite pluton now
shows horizontal and vertical zoning: from the north-west
side of the mountains the S-type granites substitute the
I-type tonalites towards the south-east, and the medium/
coarse-grained I- and S-type granitoids are vertically over-
lain by their metasomatically altered equivalents in tectonic
position forming a granite duplex (Fig. 9).
