Geochemical specialization of Upper Proterozoic complexes of the Prikolymian Terrane, NE Russia
The paper considers the distribution of the base metal chemical elements in the Upper Proterozoic structural-matter complexes of the Prikolymian Terrane, NE Russia. Their chalcophylic geochemical specialization was established. Based on the sialic type of geochemical specialization, the maturity of the continental crust in the Upper Proterozoic was suggested. It was shown that epigenetic mineralization inherited the geochemical specialization of the enclosing Late Proterozoic complexes. This fact is evidence of active tectono-magmatic evolution of the Prikolymian Terrane in the Phanerozoic time.
