| 摘 要： | 南龙王庙金矿位于抚顺-清原太古宙绿岩带内.金矿赋存于太古宇鞍山群红透山岩组上部的火山岩-碎屑岩建造中，容矿围岩为磁铁角闪石英岩、黑云变粒岩及浅粒岩.矿体产出受韧性剪切带控制，金矿体沿韧性剪切带分布，呈透镜状、脉状、似层状，矿体规模一般较小.矿体为浸染-细脉含金黄铁矿和含金黄铁矿石英脉.金以自然金形式产出.硫同位素源自深部，铅同位素表明矿质来自绿岩，氢氧同位素指示成矿流体是变质水和大气降水的混合.研究认为南龙王庙金矿为具层控性受韧性剪切带控制的变质-大气降水混合热液型金矿.

| Abstract: | The Nanlongwangmiao gold deposit in Liaoning Province, tectonically located in the Archean Fushun-Qingyuan greenstone belt, occurs in the Hongtoushan volcanic-clastic rock formation of Anshan group, with wallrocks of magnetite amphibolite quartzite, biotite granulite and leucogranulitite. The orebodies, commonly in small scale, are controlled by the ductile shear zone, presented in lenticular, veined and layered shapes as disseminated-veinlet Au-bearing pyrite ores and Au-bearing pyrite quartz veins. The Au appears as native gold. The S isotopes are derived from the deep. The Pb isotopes show that the ore matters are from the greenstone. The H and O isotopes indicate that the ore-forming fluid is the mixture of metamorphic water and meteoric water. It is concluded that the Nanlongwangmiao gold deposit is of stratabound ductile shear zone-controlled metamorphic-meteoric mixed hydrothermal type. |
