New data on the basement of the north-eastern framing of Krasnoleninskiy arch

Authors: S.V. Shadrina, A.P. Kondakov (Tyumen Branch of SurgutNIPIneft)

Key words: basement rocks, weathering crust, U/Pb dating, structure-formation zone, Western Siberia.

Analysis of the new data on the mineral-petrographic, petro-geochemical composition and the absolute age of rocks, forming the crystalline basement in the area of Rogozhnikovskiy uplift and Malootlymskiy swell (north-eastern framing of Krasnoleninskiy arch), the study of core material and also the results of geophysical studies allowed to identify three structural -formation zones, differing in composition, structure and age of the rocks. The results of research are different from the existing concepts of the basement rocks of this area. A new medium-scale geological scheme of pre-Jurassic basement of north-eastern framing of Krasnoleninskiy arch, significantly refining the scheme of predecessors, is drawn.
