Auriferous Paleozoic Accretionary Terranes Within the Mongol-Okhotsk Suture Zone, Russian Far East

摘要

The Mongol-Okhotsk belt consists of detached fragments of the Circum Pacific fold belt which have been trapped within the Mongol-Okhotsk fold belt. In its western part, the structures of the belt form an east-facing loop that is not connected with the other orogenic structures of Central Asia. In the eastern part of the belt (the Mongol-Okhotsk suture zone) the terranes form a zone between the SIberian craton to the north and the Bureya composite terrane to the south, that is linked with the Circum Pacific belt. The accretionary complexes vary from Late Precambrian-Carboniferous in the west to Cambrian-Jurassic in the east. The terranes developed due to a progressive westward stacking of the accretionary complexes during the process of accretionary growth.
