The basic conditions in which gas shows in frozen rocks of cryogenic strata are related to their composition, genesis and structure are defined. The stages of development of submarine cryolithogenesis in marine deposits in the Pleistocene, peculiarities of its development under a sequential change in facial conditions of sedimentation and freezing of bottom sediments of the shelf are shown.
