| Abstract: | Studies on the ore-control features of strata and structures, the characteristics of chemical composition, trace elements, orebodies and ores, and the isotope compositions of O, S,and Pb from pyrite in ores have demonstrated that the metallogenetic medium water of thePangjiahe gold deposit should be synchronous formation water and the metallogenetic materials come from wall rocks of the Lower Donggou Formation of the Upper Devonian series.The genetic type of the gold deposit is a micro-disseminated type formed by leaching of hydrothermal solution. |
