【 摘 要 】

Methods of scanning tunneling and atomic force microscopy, nano-gold deportment in sulfides was studied in carbonaceous shale deposits Kyuchus (Yakutia). Chemical and ionplasma etching in oxygen and argon medium was used for nano-gold detection. It is shown when bombarding with oxygen ions pyrite and arsenic pyrite are etched layer by layer, revealing nano-gold particles. Deformation structures of adjacent sulfide and their interaction with gold separation had been investigated. In arsenic pyrite of early stage gold is found in patterned solid solution.
