Geochemical patterns of epithermal ore formation in the Okhotsk–Chukotka volcanoplutonic belt (Northeast Russia)

Аннотация

Ores of epithermal Au–Ag deposits of the Okhotsk–Chukotka volcanoplutonic belt are characterized by enrichment in a wide spectrum of elements in relation to the average upper crustal values. The data obtained show that the host volcanic rocks are the most likely sources of minor elements and REEs for the fluids that formed epithermal Au–Ag deposits of the Okhotsk–Chukotka volcanoplutonic belt.
