摘要
伽师铜矿位于塔里木古陆块中的古生代前陆盆地,地质构造简单,分为3个矿段、7个矿体。对矿段和矿体的地质特征及矿床成因分析表明,该矿区砂岩丰富,容矿性好,砂岩顶底板的泥岩充当了良好的隔挡层,石膏层使矿液上流,致使富集成矿,其矿床成因类型属下第三系泻湖相沉积层控型砂岩铜矿床。
Qieshi Copper Ore is located at Paleozoic foreland basins in the Tarim ancient landmass, with simple geologic structure. It is divided into three ore blocks and seven ore bodies. Through the analysis on geological characteristics and genetic mechanism of ore deposit for ore blocks and ore body, it is said that there is abundant sandstone, and the good ore containing capacity. The mudstone of the sandstone roof and floor acts as a good blocking layer, and the gypsic horizon makes the ore solution flow up, resulting in the enrichment of mineralization. The genetic mechanism belongs to the tertiary lagoon facies sedimentary layer controlled sandstone copper deposit.
