Abstract

The Mariánské Lázně fault (MLF) is a NW-SE striking structure in western Bohemian Massif (Czech Republic), which controls the eastern limit of the Cheb-Domažlice graben at the length exceeding 100 km. To study neotetconic activity of the MLF, we analyzed the related fault scarp and longitudinal river profiles and SL indices of the streams crossing the MLF to identify knickpoints and other anomalies potentially related to activity of the MLF.

In addition, we have used morphometric indices such as hypsometric curves, basin elongation ratio, topographic asymmetry, etc. in the Cheb basin to determine whether tectonic or erosional processes have played a dominant role in the development of landscape. Moreover, we mapped and classified the Ohře River Pleistocene terraces within the Cheb basin which appeared to be displaced by the MLF.
