Abstract

<strong class="journal-contentHeaderColor">Abstract.</strong> The Polish part of the Western Outer Carpathians lineament network was analysed based on the GMTED2010 digital elevation model. Lineaments were identified in the visual screening of the hillshade model. To the best of our knowledge, no one has studied the geometrical properties of the network with relation to the topological ones. The NetworkGT QGIS toolbox was applied to identify the nodes and branches of the network, as well as to calculate the topology parameters. Our aim was to find differences between the western and eastern parts of the Western Outer Carpathians; therefore, the analyses were carried out in six sectors chosen based on the geographical subdivision in the geological context: three in the north, mainly the Silesian unit; and three in the south, mainly the Magura unit. We found general agreement of the identified network with the photolineament map; however, some of the photolineaments are not confirmed by digital elevation model (DEM). We found that the topological parameters of the networks change from west to east, but not from north to south. There are areas of increased interconnectivity, especially the Nowy SÄ cz Basin, where the lineament network may reflect a complicated system of cross-cutting deep-rooted fault zones in the basement.
