ZDARKY-PSTRAZNA DOME: A STRIKE-SLIP FAULT-RELATED STRUCTURE AT THE EASTERN TERMINATION OF THE PORICI-HRONOV FAULT ZONE (SUDETES)

The trans-border area of the Sudetes between Zd'arky and Pstrazna has attracted Prussian/German, Austrian, Czech and Polish geologists since the middle of the 19(th) century. The history of mapping of this area reflects the scientific development of geological centres in Berlin, Vienna, Prague and Wroclaw. This paper presents a description of the oldest geological maps of Lower Silesia in the context of changing knowledge on the Carboniferous and Cretaceous stratigraphy and on the tectonics of the region. On the basis of DEM and field studies the author presents his own geological map of the area of the Pstrazna Elevation together with a description of the local structural geology. A regional structural model is suggested, that explains all the local elevations as having developed in response to a dextral strike-slip activity of the Zd'arky-Jakubowice Fault during late Tertiary to Recent times, at an eastern extension of the Porici-Hronov Fault Zone.
