Abstract (in english)
   The conditions of the deformation in the Veporicum crystalline basement are estimated at middle to upper greenschist facies or the lower part of amphibolite facies; according to these first results, max. T reached approximatelly -450-500 C at P- 3-4 kbar. The observations from the Permo-Mesozoic cover sediments suggest that deformation occurred in the greenschist facies conditions at a temperature estimated at 350 C (max. 450 C according to crystal plasticity of quartz in the eastern part), or only at anchimetamorphism. Our observations suggest that the major paragenetic transformations reflect probably the strong Alpine overprint. We assume that only relics of higher metamorphosed rocks from the so-called "hybridic complex" in the southern part of the Veporicum basement could bear records of Late-Hercynian events
