OUTLINE OF STRUCTURE OF MESOSOIC SEQUENCES OF THE HUMENSKÉ VRCHY MTS

Abstract

WNW - ESE horst of Mesozoic sequences of the Humenské vrchy Mts. forms NE margin of the East-ern Slovakian basin filled by Neogene vulcanosedimentary formations. They consist of Middle Triassic (Ani-sian) to Middle Cretaceous (Lower Cenomanian formations) belonging to Križna superficial nappe unit of the Western Carpathians. Structurally the sequence is composed of four directional sheets (i.e. Jasenovská, Klako-činy, Kocovo, and Hôrka sheet) dipping to N - NNE. The sheet structure has been formed during Miocene back-ward thrust of the Paleogene flysch formations. Other dislocations of the same and N - S direction are of younger age. They are bound to final formation of Eastern Slovakian basin and they segment the horst to individual elevation and normal fault blocks.
