EVOLVEMENT OF THE METALLIC MINERALIZION IN THE SIKHOTE-ALIN METALLOGENIC PROVINCE

There Sikhote-Alin tectonic belt is composed of three tectonic units, i.e. Khanka massif, Laoyeling-Grodekovo island arc and East Sichote-Alin orogenic belt. The evolvement of metallic mineralization in the region can be divided into three periods. From the end of Riphean to the end of Silurian, iron(manganese) deposits and lead-zinc deposits were formed by exhalative-sedimentary mineralization in Khanka area, with also some magmatic hydrothermal tin deposits. During Middle Permian, epithermal gold (sliver) deposits, as well as metamorphic-hydrothermal gold deposits, were formed in Laoyeling-Grodekovo island arc region. Through Jurassic to the end of Paleogene, skarn type tungsten deposits, epithermal gold (sliver) deposits, skarn and vein types of boron and lead-zinc deposits, and vein gold deposits were formed in the East Sikhote-Alin tectonic belt.
