FEATURES OF TECTONIC DEVELOPMENT OF STRUCTURES IN THE MIDDLE OB BY CORRELATION OF THICKNESS ANALYSIS

Abstract

The article is devoted to the main patterns of tectonic development in the Middle Ob for the period from the tops of the middle Jurassic to the Eocene. It is shown that during this period of time in the tectonic development of the territory there were periods of quiet sedimentation and very active tectonic activity. In the history of the tectonic development of the Middle Ob four major stages are distinguished: two is quiet (the Jurassic and the Upper Cretaceous) and two are very active with large-scale multidirectional movements that led to a significant increase in the amplitudes of the structures (from the Cretaceous to the roof of the Cenomanian century).The article describes the methodology of the correlation analysis used in the study of the history of tectonic development in the territory.
