摘　　要：金厂金矿床为一集爆破角砾岩筒型、细脉浸染型及脉状蚀变岩型金矿化于一区的特大型岩金矿床,3类矿化类型矿石中普遍发育含固体子矿物多相流体包裹体(子矿物数≥4),除盐类(Na Cl)子矿物外,还常见有不透明子矿物,扫面电镜能谱分析结果表明其主要为黄铁矿、黄铜矿及闪锌矿等硫化物子矿物。这些硫化物子矿物与3类矿化类型矿石中发育的主要金属矿物组合一致,表明成矿物质主要来自于岩浆侵入体。Jinchang Gold Deposit is a super large-scale rock gold deposit,incorporating in itself explosive breccia pipe type,fine-vein disseminated type and alteration rock type mineralization. Daughter-mineral bearing multiphase fluid inclusions（ number of daughter minerals≥4） widely develop in ores from all 3 types mineralization. In addition to salt daughter minerals（ Na Cl）,opaque daughter minerals often can be observed. Scanning electron microscopy study shows that they are mainly such sulfide daughter minerals as pyrite,chalcopyrite and sphalerite. These sulfide daughter minerals are is consistent with the mineral assemblage observed in ores from all 3 types mineralization. This gives direct evidence that the ore-forming materials mainly came from magmatic intrusions.
