Abstract

The first results of SHRIMP dating of magmatic complexes and associated gold–silver deposits and ore occurrences (Kupol, Dvoinoe, Moroshka, and others) in the Chukotka sector of the Russian Arctic coast are discussed. The petrological and isotopic–geochronological data are used for reconstructing their formation conditions.
