Placer gold composition and provenance studies in the Kuznetskiy Alatau and Western Sayan, South-East Siberia : results of field trip, Summer 2014.
This article presents the results of a study of gold samples obtained by students during a practical field trip in the summer of 2014. Placer gold samples retrieved from four rivers in southeast Siberia (Khakassia and Tyva territories) by panning and sluicing were described and analyzed compositiona...
