Okhotsk-Chukotka Volcanic Belt

The Okhotsk-Chukotka Volcanic Belt (OCVB) is a Cretaceous volcanic belt in the Russian Far East region of northeast Asia.

It is found in Chukotka Autonomous Okrug and Khabarovsk Krai of northeastern Russia.

Geology[edit]

The volcanic belt is one of the largest subduction-zone related volcanic provinces in the world, stretching some 3,200 kilometres (2,000 mi) and comprising about 2 million km3 of volcanic and plutonic material.

The volcanism within the volcanic belt was related to the subduction of the ancient Kula Plate, which moved in a northward direction about 55 million years ago.
