Opis:: The paper presents comparison of geological interpretations based on Landsat MSS image and DEM-based image, covering the same area of the Carpathian Mts. Individual interpretations of both images made by 16 interpreters were gathered into 2 multi-coverage interpretations (MSS and DEM). Results were compared— MSS with DEM, and DEM with geology. The DEM-based interpretations contain more lineaments with greater total lengths than MSS-based, but geological relationship of some lineaments is still unclear.

Opis:: This article presents the results of rock hardness tests conducted in the Ślęża Massif to decipher the relationships between the geological structure and relief. It has been shown that all rock types of the massif represent similar mechanical strength. The highest mean strength was found in granite of the western slopes and the foothills of Mt. Ślęża, whereas the lowest strength is typical of gabbro from the central part of the massif, its summit and the eastern and southern slopes. Thus, the traditional concept emphasizing gabbro as being the most resistant rock has not been confirmed. There is also no evidence of higher strength of rocks within the massif, as compared to those in most of its surroundings. Variable mechanical strength is probably responsible for slope mesorelief (mid-slope benches and ridge lines), yet the hypothesis that the resistance of gabbro changes perpendicularly to the contact with granitoid intrusion has not received support. Higher mean Schmidt hammer rebound values and lower standard deviation occurring below 450 m a.s.l. are interpreted as a result of interaction between the structural factor and glacial exaration during the Odra Glaciation.

Opis:: The article presents a new concept of structural control on the Outer Carpathians relief. The Carpathians’ relief development originated in the stage of sedimentary basin deposition (e.g., gravitational positioning of fragments of rock massif), as well as in the compressional stage of the orogen formation, and, finally, in the stage of secondary tectonic deformation, such as: strike-slip faulting, radial extension, and great extensional collapse of the Carpathian massifs. The difference in elevation between the Beskidy Mts. and Carpathian Foothills belt is caused by the structural position of these segments of rock massifs within an accretionary prism formed during the compressional stage. The tectonic elements formed during the earliest stage of compression (Magura, Dukla and southern Silesian units forming the High Beskid zone) attain the highest structural and elevation position, whereas the elements included as the last ones to the accretionary prism (Sub-Silesian and Skole units) take a lower topographic position, forming the foothills belt. A concept that gravitational collapse generated back-thrusts and tectonic exhumation of the Carpathian massifs allows us to explain seemingly considerable erosional unroofing of the Carpathian surface, estimated at several kilometres. Alternating position of elevated and lowered mountain ridges (Bieszczady–Beskid Niski–Beskid Wyspowy–Beskid Makowski Mts.) can be explained by their association with a major strike-slip fault. Chaotic complexes frequently occurring in the Carpathians are very important for the relief transformation and development of river network (controlled not only by dislocations, but also by chaotic complexes), as well as for the presence of erosional remnants (isolated hills representing blocks in matrix).
