Abstract

Summary

Within the Chon group of fields, the petrographic composition of Foundation rocks and weathering crust was studied, the profile of the residual weathering crust and Foundation variability was determined and typed. The obtained results, after linking with GIS and 3D seismic data, can be used to predict the thickness of weathering crust, faults in the Foundation and refinement of its block structure, as well as in the reconstruction of the paleorelief of the crystal Foundation at the time of formation of basal horizons. The study of the profile of the residual weathering crust have led to the conclusion about the existence of arid climate at the period of its formation and accumulation of basal layers of the sedimentary cover, which in turn characterizes the type of the sedimentary basin, the composition of the original precipitation and their cementing substances, as well as, in some sense, determines the post-sedimentary processes.
