Abstract

The study area is located in the eastern part of Veporské vrchy Mts. and is composed of several palaeo-Alpine tectonic units which are sealed by Cenozoic formations and volcanites. The palaeo-Alpine units differ by degree of metamorphism, deformation, age, and lithological composition. The Vepor Unit, which consists of metamorphosed Variscan crystalline basement and the Permian to Triassic Foederata Group, forms the lowermost structure of the palaeo-Alpine nappe stack in this area. The Vepor Unit is overthrust by (from the bottom to the top): (a) newly detected epimetamorphosed Carboniferous deposits of the Furmanec Unit which could by correlated with the Ochtiná Nappe of the Gemer Unit s.l. or with the Nižná Boca Formation of the Choč Nappe; (b) the unmetamorphosed “Lower” Muráň Nappe, newly described nappe unit within this area but with not well-known tectonic affinity; and (c) the unmetamorphosed Muráň Nappe s.s. of the Silica Unit which represents the uppermost portion of the palaeo-Alpine nappe pile. Post-nappe Upper Eocene to Oligocene remnants of sedimentary deposit together with remnants of the originally voluminous Neogene Vepor Stratovolcano are the youngest features of geological structure of the study area.
