| 摘 要： | 甘肃枣子沟金矿是一座位于西秦岭西段夏河-合作金多金属成矿带的大型金矿床。稀土元素配分曲线右倾，为轻稀土富集，负Eu异常明显，表现为壳源岩浆的特征。矿石中的微量元素分布与闪长岩相似，说明成矿热液来源于闪长岩。金矿石中黄铁矿δ34S在-7.47‰～-9.26‰之间，表明硫主要来源于岩浆期后热液。次生包裹体均一温度为120～270 ℃，属中低温热液型。

| Abstract: | Rare earth element in Zaozigou gold mine is scattered in curve rightward with abundant light rare earth.Negative Eu is extraordinarily obvious there,which is characterized by melted crustal magma.Microelements scatter-ing in the ores are similar to diorite,which explains that mineralized hydrothemal originated from diorite.Pyrite δ34S in gold ores is about-7.47‰～-9.26‰,which indicates that sulphur mainly originated from post-magmatic hy-drothermal.The average temperature of secondary inclusion is 120～270 ℃,which belongs to middle and epithermal deposit. |
