SIGNS OF MESO-CENOZOIC COVER GAS PRESENCE OF THE NORTH-WESTERN PACIFIC ABYSSAL FLOOR
Signs of the gas & possibly oil presence in the Meso-Cenozoic, sedimentary-trap cover of the NW Pacific abyssal seafloor (seaward of the Kuril deep-sea trench) are described from results of oil-gas geological interpretation of the CDP 1 profile and seismic continuous profiles (SCP): «field» type anomalies, gas windows, columns, and «threads» as zones of break or visible weakening of reflector intensity. Probable sources of hydrocarbons (originally-sedimentary deposits of the Early Tethys in Layer 4) and peculiarities of their thermogeneration discuss (friction heat of gravitational glide of Layers 1-4 or of the oceanic crust).
