Wybrane analizy geoinformacyjne w badaniach związków budowy geologicznej z rzeźbą terenu Obniżenia Chabówki-Jordanowa

Abstract

This study presents the results of researches on correlation between geological structure and terrain morphology of the Orawa-Jordanów Depression GIS tools and software, as well as remote sensing methods were used in the investigations Lineaments method basing on DEM data was applied too The research area bearing foothill morphology is distinctly depressed from the surrounding it Beskidy ranges The foothills are characterized by lower high peek and relative highs than the Beskids Morphology of the Chabówka-Jordanów Depression is associated with tectonic structure The tectonics determines that Chabówka-Jordanów Depression is intermountain tectonic trough Completed analysis allowed to conclude, that ridges on this terrain are mainly formed of the thick-bedded sandstones of the Magura Formation, and depressions and valleys are dissected in older rocks represented by shale and sandstone-shale complexes Directions of the main ridges and valleys are parallel to extensions of the main fold structures Lineaments marked in studied terrain correlate mainly with faults The lineaments method allowed to conclude that some of valleys exploit the transverse faults
