The ubiquitous occurrence of subparallel topographic linear systems of various scale (a few hundreds of kilometres to meters scale) and of geographical direction were detected there, frequently with en echelon geometry and regardless of bedrock lithology. The geomorphological lineaments are mostly of composite character integrating diverse landscape features: hillslopes, river valleys or boundaries between individual topographic blocks. Especially, a tight fitting of regional fluvial system the linear scheme of basement is evident. That is why a passive adjustment of recent surface processes to older structural features has unequivocally been the dominant evolutionary mechanism of the outlined landscape pattern. However, in a few specific cases a development of lineament arrangement involving non-negligible active tectonic component could not yet be excluded including existing related pull-apart residual settings of recent sediments or more tens kilometres long linear suites of stream offsets, mainly in some sedimentary areas. Cross-checking with other data types such as geological (confirmed faults, associated young sedimentary sites), geophysical (regional fields, nearby earthquake events) or geodetic (significant horizontal movements indicated by Global Navigation Satellite Systems or vertical movements detected by repeated precise leveling) is inevitable to select the best places for eventual verification of active kinematics. A number of linear structures not yet present in geological maps were highlighted.
New full-area geomorphological analysis of the Eastern part of the Bohemian Massif, the most complex segment of this Central European Variscan domain with more older Cadomian elements and overlying younger cover units located in the foreland of the Cenozoic Alpine-Carpathian junction region, was carried out primarily based on recent real LiDAR elevation data visualized in GIS. The ubiquitous occurrence of subparallel topographic linear systems of various scale (a few hundreds of kilometres to meters scale) and of geographical direction were detected there, frequently with en echelon geometry and regardless of bedrock lithology.Pracoviště Ústav geoniky Kontakt Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Rok sběru 2019
