| 中文摘要: |
| 四川石棉西部碳酸盐岩中的金矿床产于泥盆系中统,受层间蚀变破碎带控制。围岩蚀变类型有硅化、碳酸盐化和绢云母化。矿石矿物组合为黄铁矿、黝铜矿、黄铜矿、方铅矿、闪锌矿和Au-Ag系列矿物,具Au-Cu-Ag-Pb-As-Sb-Bi的元素组合,并显示一定的垂直分带规律。其成因类型为地下热卤水型。矿床受地层、岩性和断裂的控制明显。并阐明了金矿床的成矿过程和勘查准则。 |
| 英文摘要: |
| The carbonate rock-hosted gold deposits in western Shimian, occur in the middle Devo-nian system, and are controlled by the interlayer fratured zone. There are silicification, car-bonatization and sericitization in ore-hosted rocks. The gold ores have mineral association of pyrite, tetrahedrite, chalcopyrite, galena, sphalerite and Au-Ag mineral series, and element association of Au-Cu-Ag-Pb-As-Sb-Bi, which show certain vertical zonal regularity. The de-posits were controlled obviously by strata, lithology and fracture. Finally, the ore-forming process and exploration criteria are discussed. |
