Tectonic movements and protomagmatic structures

Abstract
The formation of the granitoid massif is associated with the Laramian phase of Alpine folding and is dated as Upper Cretaceous. Having broken through the sedimentary-volcanogenic rock sequence, the intrusion became consolidated in the central part of the Okhotsk–Kolyma watershed, which is the southwestern limb of the Gizhigin synclinal zone. The massif is elongated in the northeastern direction conformably with the dominant strike of the host rocks and in plan has a lenticular shape. The length of the body at its greatest extent is 63 km, with a maximum width of not more than 18 km.
