NEOTECTONIC MOBILITY OF THE ROZTOCZE REGION, UKRAINIAN PART, CENTRAL EUROPE: INSIGHTS FROM MORPHOMETRIC STUDIES

摘要

The results of geological, geomorphic and hydrogeological research indicate spatially variable neotectonic activity of the Ukrainian part of the Roztocze region. This ac tivity is confirmed by analysis of some geometric and morphometric coefficients (especially drainage basin elongation ratio, drainage basin circulatory ratio, drainage basin shape and lem niscate coefficient), which were calculated for 1646 drainage areas of the 3rd to 6th order, and morphometric linear coefficients (mountain-front sinuosity index and valley floor width-valley height ratio coefficient), which characterise the fault scarps. The south-western margin of the Rava Roztocze and Yaniv Roztocze regions, follow ing NW-SE-trending faults, be longs to structures of the 1st or 2nd class of relative tectonic activity.
