Związek morfologii wybranych osuwisk z budową geologiczną Karpat i zapadliska przedkarpackiego w świetle analiz numerycznego modelu terenu
Abstract
The relationship between the selected landslide morphology and the geologic setting of the Carpathians and the Carpathian Foredeep based on the digital terrain model.
A b s t r a c t. This article presents the results of digital terrain model analysis and field observations related to occurrence of characteristic forms in landslide surface that may indicate the geological setting. Based on these observations, three characteristic structures were selected occurring on many landslides in the Carpathian Mountains and the Carpathian Foredeep. The former are the wrinkle structures visible on the digital terrain model associated with movement along the bedded surface. The other are the streak structures linked to the occurrence of gravels and sands on the clays. The third mogul type structures are related to cylindrical sliding surfaces formed in clay.
