Tectonic position of the Roztocze region in the light of the evolution history of the Carpathian Foredeep
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2015, Vol 462, Issue 462
Abstract
The paper presents new concept of the tectonic development of the Roztocze region, uplifted as a tectonic horst structure. Measurements of tectonic discontinuities (joints, faults) in the rocks building the Roztocze region, as well as the analysis of Neogene deposits distribution on the Roztocze horst, have allowed authors to establish several tectonic stages of the Roztocze development. Thrusting of the Carpathians to the north caused the formation of a strike-slip (dextral) fault along the eastern part of their foredeep (and associated flower structures and horse tail structures). As a result of forebulge structure formation, caused by progressive thrusting of the Carpathian orogen and isostatic uplift of their foreland, strike-slip faults were reactivated as reverse-slip faults. Subsequently, due to collapse of the Carpathian massifs, discontinuities were again reactivated as dip-slip faults. The footwall elevation associated with normal faults formed into the Roztocze Horst and divided region to blocks, causing a neotectonic uplift of the Roztocze region.
