GEOLOGICAL AND GEOPHYSICAL MODEL OF THE CENTRAL PART OF THE YENISEI-KHATANGA REGIONAL TROUGH BASED ON THE RESULTS OF COMPREHENSIVE INTERPRETATION OF MODERN SEISMICAND GRAVITY-MAGNETIC SURVEYS
View through CrossRef
New data on potential fields are presented, compared with previous ideas about the regional structure and rift genesis of the Yenisei-Khatanga regional depression basement. Our 2D modeling based on geophysical data confirms the results of previous works regarding the identification of two types of the basement, and is consistent with the gravity-geodynamic concept of the formation of the Yenisei-Khatanga regional trough and the tectonic structures that complicate it, such as the Rassokhinsky and Balakhna megaridges. Also, as a result of our study of potential fields, the presence of a large volume of magmatic masses of ultrabasic and basic composition in the axial part of the Yenisei-Khatanga regional trough, Permian-Triassic age, was established, which confirms the rift mode of the region's development.
