REVISION OF MAGMATIC COMPLEXES AND AGE OF GOLD DEPOSITS WITHIN SOUTHERN PART OF VERKHOYANO-KOLYMA OROGENIC BELT (ISOTOPIC GEOCHRONOLOGY ASPECTS)

We suggest identifying magmatic complexes (formation) in a specific structural zone based on similar age and relationship with mineralization as the main criteria. Tree main igneous complexes proposed to distinguish within the southern part of the Verkhoyansk-Kolyma orogenic belt, the Upper Jurassic Nera-Bokhapcha diorite-granitoid to lamprophyre dike swarms, the Upper Jurassic Kolyma granitoid batholiths, and the Upper Cretaceous Omsukchan leucogranite intrusions. The age of gold orogenic mineralization in the province is Valanginian-Hauterivian. It does not correlate with any of the identified igneous complexes, and is probably associated with hydrothermal activity triggered by orogenic deformation processes
