| Abstract: | Based on the study of sedimentary disseminated pyrites in Late Mid-Proterozoic Mukeng formation, the paper has demonstrated that double zonal texture, i.e. compositional and genetic zonation existed in gold-bearing pyrites. Its rim, subject to the reworking of fluids and reequilibrium, genetically proved sedimentary and also released a large amount of gold which turned to be potential sources; In a contrary, its core stayed unchanged because of closed protection effect. The zonal texture within pyrites shows great importance on gold prospecting and exploration. |
