|Genesis conditions of the Riphean-Lower Cambrian sand and pelitic rocks in petroleum potential evaluation of Pred-Patom foredeep
|Oil and gas potential of the Riphean-Lower Cambrian strata in the central and eastern parts of Pred-Patom foredeep was evaluated using analytical study of sedimentation environments, composition and reservoir properties of terrigenous rocks, minerals and sealing features of pelitic rocks. Dynamo-genetic diagram was constructed as a result of cumulative curves’ correlation. Preliminary information on the sedimentation conditions of terrigenous rocks was obtained. Marine and coastal facies are identified. Mineralogical study of pelitic rocks was conducted. Capacitance-filtration properties of terrigenous and pelitic rocks were evaluated.
Key words: Pred-Patom foredeep, grain composition, mineral composition, facies, sedimentation conditions, Riphean, Vendian, Lower Cambrian.
