About platinoid findings in primary rocks of gold-silver deposits of Norther Chukotka

Abstract

The paper presents the results of the study of ores and the features of the mineral composition of platinoids first discovered in ores of the deposits of Northern Chukotka: Kupol, Dvoynoye and Sentyabrskoye, which are of the gold-silver epithermal type. In addition to the presence of gold, silver, and tellurium, which is characteristic of this type of ore, the values of the platinum content are founded. In conjunction with the results of research in Primorye, it is obvious that it is necessary to single out a unified Chukotka-Okhotsk-East-Sikhote-Alin transregional volcanic-plutonic belt which deserves more detailed studies on platinoids.
