Abstract

Density sections of the Upper Proterozoic-Paleozoic cis-Yenisei sedimentary basin were numerically modeled to show that the gravity mechanism was sufficient to bring about linear deformation structures. The main conditions of their formation and development have been determined. Comparative analysis of the results of modeling with variations in initial parameters shows an important role of dolomite interbeds in the formation of structures in the section of Cambrian evaporates. The specific evolution of the structures was related to the specific basin sedimentation and the subsequent tectonic evolution of the region as a whole. The conclusion has been drawn that the tectonic influence of neighboring folded zones might have triggered salt tectogenesis.
