Abstract

The Pohorelá line (PL) is an important tectonic element dividing the major pre-Cenozoic lithotectonic units of the Northern and Southern Veporicum. Moreover, the PL separates occurrences of the Gemericum, Meliaticum and Silicicum on its S–SE side against the Fatricum and Hronicum on NW side. Continuation of the PL towards the SW was unknown because the pre-Cenozoic basement of the Veporic Unit is covered with Cenozoic (Neogene) volcanics and volcanosedimentary rocks. Reinterpretations of the deep boreholes data reveal a southwest continuation of the PL to the Poľana, Javorie, and Štiavnica stratovolcanic complexes basement and then further towards the SSW.

Key words: Pohorelá line, Pre-Cenozoic basement, Veporicum, Neovolcanics, Western Carpathians
