Раннемеловые гранитно-метаморфические ассоциации и оруденение Золотого хребта (Восточная Чукотка)

Abstract

The geological characteristic of the Golden Ridge, one of the oldest gold-bearing areas in the North-East, is presented. The important role of the Early Cretaceous metamorphism and the associated granitoid plutonism controlling the orogenic gold mineralization and the placer gold content, which is typical for the granite-metamorphic domes of Chukotka, is demonstrated. The area prospects for the Late Cretaceous copper-molybdenum-porphyry mineralization are characterized. The potential of ore and placer gold in the area discussed is assessed.
