The structure of the Silesian Beskid Block in the Vistula River source area in the Western Outer Carpathians (southern Poland)

This paper presents new results of a detailed structural analysis the bedrock Vistula source area within Silesian Beskids (Outer Western Carpathians, S Poland). The study is composed Upper Cretaceous flysch series Godula Beds and Lower Istebna Beds. located on southern limb Szczyrk Anticline Beskid Block. research based cartographic field work remote sensing digital elevation model from LiDAR data. analyses were supported by extraction topolineaments their spatial analysis. presented show that monoclinal structure can be characterized systematic joint pattern, which determined existence faults fault zones. Moreover, differences in fracturing sedimentary strata hidden fracture zones, not visible previous map view. Most are related to an orthogonal system, whereas transverse longitudinal connected with fold thrust structures exposed outcrops reflected topography. Kinematic shows NW–SE-trending underwent dextral movements, while ENE–WSW-trending recorded sinistral displacements. Furthermore, older strike-slip oblique-slip displacements along overprinted normal dip-slip faulting. tectonic relief data no Gościejów Syncline northern part area, was depicted maps. In conclusion, faulting damage zones interpreted as being posttectonic, gravitational collapse rock massif. Its recognition very important for further relationships between mass movement characteristics, such geometry kinematics landslides.
