摘要
佘家院银金矿受陡山沱组与耀岭河组之间的顺层滑脱构造控制。硫同位素、铅同位素特征说明成矿物质来源于围岩和上地壳。成矿经历中—低温和低温两个阶段,与成矿期和后期变形两个阶段相一致。佘家院银金矿成矿类型为复合内生型。建议在武当隆起西缘褶皱倾伏端之滑脱带寻找富矿体。
Shejiayuan silver gold deposits are controlled by Bedding decollement structure between Doushantuo Formation and Yaolinghe Formation.Characteristics of sulfur isotopes and lead isotopes show metallogenic material origin in wall rock and upper crust.The mineralization experience two phases including low medium temperature and low temperature,consistent with mineralization and later deformation.Type of Shejiayuan silver gold deposits is of composite endogenous.
