Abstract

P-T conditions of the Alpine regional metamorphism of carbonate successions which form the cover sequence of the southern Veporicum crystalline basement have been determined. The P-T estimates were calculated on the basis of microprobe chemical analyses of equilibrium mineral assemblages together with analyses of bulk rock chemical composition. The calibrated geothermic reactions Cal-Dol and Kfs-Phl were used. Geothermometric and geobarometric data were obtained using the SOLVCALC, TWQ and PERPLEX software programs in combination with phengite geobarometry. The metacarbonates were formed from a sedimentary-carbonate protolith in low-pressure and low-temperature conditions of greenschist facies in the kyanite stability field: TCal = 354-476°C, TAb-Or = 329-453°C, P = 0.3-0.5 GPa, during Cretaceous orogeny
