摘要
通过对甘沟铅锌矿的地质矿产勘查,已初步查明区内铅锌矿含矿层位为下志留统梅子垭组,圈定了4条铅锌矿体,已获铅锌矿资源量9.78×10^4t。该含矿层矿体单个长180-580 m,平均厚度1.22-1.79 m,平均锌品位5.42%-8.37%,平均铅品位1.93%-11.04%。认为该矿床成因属沉积-变形变质热液改造型矿床。
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.
