Abstract: Calcretes have developed in soils of the Zitny ostrov region in response to the mutual interactions between the different prevailing geological and environmental conditions. The evapotranspirative climatic conditions and shallow hydrocarbonatic groundwater play a very significant role in this aspect. Different micromorphological characteristics have been described. The observed microstructures are of massive, intergrain micro-aggregate types, with occasional occurrence of the pellicular type also, in addition to the vughy, intergrain channel, and fissure microstructures. The porosity of these calcretes is dominated by vughs, channels, and planes. There is also a dominance of monic and porphyric related distribution patterns, and rarely of the chitonic type. Different pedogenic features are of special interest, they represent mainly void coating and infilling, in addition to pedofeatures of pseudomorphic, textural and impregnative types, nodules, intercalary crystals, and recrystallization.
