Landscape-Forming Significance of Red Sediments of the Permian-Triassic Facies Complex

Abstract

The aim is to analyse the role of red-coloured deposits of Permian and Triassic periods of the Earth's development in landscape formation. Orenburg Urals. Materials and methods. Materials and methodological support were provided by stock materials and the results of previously published works on the study of the landscape-forming significance of reddish deposits. Results and discussion. The composition of the red-coloured sequence, stratigraphic confinement, genesis and minerals of red-coloured deposits, and most importantly, their landscape-forming significance are the priority issues put up for discussion by the authors. Landscapes, which lithogenic basis are red-coloured rocks, in the Orenburg region can be divided into three landscape areas. Conclusions. Landscape-forming red-coloured Permo-Triassic deposits of the Orenburg region, characterized by a variable facies composition that determines the confinement to them as a variety of minerals, are one of the main factors in the formation of unique natural places of the Orenburg Urals.
