New data on the age of gold-quartz mneralization at the Verkhne-Indigirsk district, Yakutia

The conducted geologic, petrographical and geochronological (isotope) investigations enabled to correlate the gold-quartz mneralization of the district with the Early Neocomian adamellite-granite complex, to which formation the regional zonal metamorphism processes are closely related. As established, the gold-quartz mneralization was formed in the final stage of zonal thermal-domal metamorphism associated with formation of collisional granitoid rocks of adamellite-granite complex in the beginning of Early Cretaceous period.
