Abstract
The article presents data on the stress state of the Schmidt Peninsula of Sakhalin Island, obtained as a result of field tectonophysical studies in 2020. The importance of studying the northern part of Sakhalin is due to the prospects of this region for the minerals search. The performed studies allowed us to establish differences in the geodynamic condition between the western and eastern coasts of the peninsula. In general, the conditions of horizontal shear (shear type of deformation) prevail among the types of stress state in the studied territory. On the east coast, there are many situations of horizontal extension, which are usually confined to the axial parts of anticlinal structures. The west coast is characterized by the stable orientation of the axis of maximum compression in the NW direction and its subhorizontal position. For the east coast, the direction of the reconstructed orientations of maximum compression is characterized by greater variability. According to the data of the reconstruction, the stress-and-strain state pattern of the Schmidt Peninsula has significant differences from the main territory of Sakhalin Island.
