Abstract
A geological density section of the Deryugin Basin (western part of the Sea of Okhotsk) was studied along the profile Sakhalin Island-Deryugin Basin-Central Okhotsk Rise. The investigations were conducted by the method of gravity modeling, which allowed us to trace the density variations of the Earth’s crust layers along the lateral. The horizontal density stratification of the Earth’s crust layers was found, which assumes a stratified-block model of its structure. The established density structure of the Earth’s crust showed that the Deryugin Basin is located in the junction zone between the Sakhalin-Hokkaido microplate and the Okhotsk Sea Plate separated by a structural suture. The western and eastern edges of the basin belong to the aforementioned plates, respectively. It was assumed that accumulations of various mineral associations are confined to the suture zone, while the “granite” layer (basement) of the Deryugin trough walls in the western edge of the Deryugin Basin presumably contains secondary reservoirs of hydrocarbons.
