PECULIARITIES OF THE STRUCTURE AND FORMATION OF THE MESOZOIC-CENOZOIC COVER OF THE PERI-KURIL BED OF THE NW PACIFIC
By interpretation results of seismic-reflection and drilling data there are considered the structure and conditions of formation of Meso-Cenozoic sedimentary-trap cover at near Kuril part of NW Pacific abyssal floor. The cover is composed by final effusive traps of Late Mesozoic, shallow-water transgressive carbonates of epicontinental Late Tethys (strata A, regional collector of hydrocarbons), opaque horizon, or strata B as its coastal regiofacies (regional cap rock), horizon C of motley abiogenic loesses of Pacifica paleoland, tuffite-siliceous-mud strata (D) of young deep-see Pacific ocean (Miocene-Quaternary). New directions and problems in marine and oil-gas geology of this region are contemplated.
Key words: NW Pacific abyssal floor, Meso-Cenozoic cover, traps, paleogeography, regiofacies, seismofa cies, fan, bench.
