| 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。矿石矿物组分为黄铁矿、黝铜矿、黄铜矿、方铅矿、闪锌矿和Ａｕ－Ａｇ系列矿物，具Ａｕ－Ｃｕ－Ａｇ－Ｐｂ－ＳＡｓ－Ｓｂ－Ｂｉ的元素组合，并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。

| Abstract: | The carbonate rock hosted gold deposits in western Shimian, occur in the middle Devonian system, and are controlled by the interlayer fratured zone. There are silicification, carbonatization 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 deposits were controlled obviously by strata, lithology and fracture. Finally, the ore forming process and exploration criteria are discussed. |
