Abstract


Structural control on the relief in the Lublin Upland and the Roztocze region.
A b s t r a c t. The main relief features of the Lublin Upland (sensu Jahn, 1956) and Roztocze were formed during the early and middle Cenozoic stages of the Meta-Carpathian Ridge morphogenesis. They are clearly
conditioned by the structure of the Upper Cretaceous-Palaeogene complex of the marginal part of the East European Craton. The following factorswere of fundamental significance for the relief development in the
study area: 1) Alpine and modern tectonic activity, which conditioned the horst nature of some morphostructures and the type of fissuring of rock massif, and 2) lithological diversity of the Upper Cretaceous-Palaeogene complex as well as the Miocene and Pliocene deposits, which influenced its strength features.
