Sedimentation Conditions and Conservation Properties of Clay Deposits of the Lower Cretaceous in the Northwestern Caucasus
摘要
Abstract
Lithological and X-ray phase analysis of Lower Cretaceous clay deposits in the northwestern Caucasus has allowed us to establish the conditions of their formation and sources of erosion of clastic material. It has been found that the studied sediments were formed in normal marine, relatively deep-water conditions of the shelf. The clays of the Lower Cretaceous are characterized as rocks with high conservation properties, which has determined not only the conservation of oil deposits but also the conservation of gaseous hydrocarbons.
