GEOCHEMICAL FEATURES OF NATIVE GOLD AS DIRECT SIGNS OF ORE FORMATION LODE AND ALLUVIAL GOLD OCCURRENCE TYPES

The features of impurity element distribution in native gold of two ore formation gold deposit types are con- sidered. A typomorphic set of elements for gold-polysulfide-quartz and gold-quartz low-sulfide mineralization was determined. Geochemical indicators for estimating ore formation types of native gold are offered. The differences in gold composition due to metallogenic specialization of regions are established. Data on the distribution of rare-earth elements in native gold are obtained, which allows to predict igneous rocks composition during gold-polysulfide-quartz deposit formation.
