| Abstract: | By geological and mineral resources exploration, the Gangou lead-zinc deposit in Xunyang County of Shaanxi Province is conformed to occur in the Meiziya Formation of Lower-middle Silurian. 4 lead-zinc ore bodies with lead-zinc resource of 9.78× 10^4 t are determined. The ore body presents layered shape with a length of 180 to 580 m and an average thickness of 1.22 to 1.79 m. The average grade of zinc is 5.42% to 8.37% and lead is 1.93 % to 11.04 %. Metallogenetic studies indicate that the Gangou lead-zinc ore deposit is a kind of sedimentary one experienced metamorphic-hydrothermal alteration. |
