摘要
The Au-Bi-Te mineralization is found and studied at the Serebryanoe deposit in Eastern Transbaikalia. The microprobe analyses of the native gold and sulfides and the sulfur isotopic composition of the sulfides are presented. The early gold-pyrite-arsenopyrite and late gold-polymetallic assemblages with sulfides, sulfotellurides and tellurides of Bi, native bismuth and gold, and Au-Bi intermetallide were distinguished. It is concluded that the Au-Bi-Te mineralization is genetically related to the porphyry monzonites of the Shakhtama complex on the basis of their 40Ar/39Ar age.
