The Stanovoy range is composed of granodiorite batholiths, mostly of the Udskaya series, which contains Mesozoic massifs in the form of intrusions of granite, granodiorite, and diorite. Seismic activity in the area is found in an east trending narrow zone, called the Stanovoy strike-slip zone. In the range, this belt is revealed by strike-slip displacement. This left fault joins the Sea of Okhotsk to the Sakhalin deformation zones. The belt formed by this zone extends to lake Baikal. The area is under compressive stresses.
