The regularities of formation of noble- and rare-metal mineralization in Cenozoic coaliferous deposits in the southern Far East

We performed system studies of age parageneses and lateral conjugation of peat and gold accumulation areas as well as the regularities of formation of noble- and rare-metal mineralization in Cenozoic coaliferous deposits in the south of the Russian Far East. The migration properties of noble metals (NMs) and their behavior in different media are considered. Based on literature data and results of experimental studies, we performed analysis and selection of the most optimal methods for the quantitative determination of NMs and trace and rare-earth elements. The experiments have confirmed the NB fugacity and have shown for the first time the scales of transportation of NMs as ultrafine particles during coal combustion. The obtained results significantly expand the notions of the migration properties of NMs and serve as the key to the solution of the problem of NM extraction in analytical and technological processes. Also, areas promising for noble- and rare-metal mineralization have been revealed in coal basins.
