| 摘 要： | 内蒙古柳坝沟金矿床位于华北地台北缘,是一个典型的以广泛发育钾长石化为重要特色的金矿床.柳坝沟矿床中矿体的石英和黄铁矿的稀土元素特征显示其早期(钾长石化阶段)成矿流体为高温、相对还原的,晚期成矿流体温度逐渐降低.石英和黄铁矿Eu正异常大小是本区寻找石英-钾长石脉型金矿的重要标型特征,Eu正异常越明显,含矿性越好.柳坝沟矿区313#脉矿体中部(163勘探线附近)以及163勘探线以东区域为下一步找矿重点区域,深部寻找石英-钾长石脉型金矿的可能性较大. |

| Abstract: | Liubagou gold deposit,lying in the north margin of North China Craton,is a typical deposit characterized by largely potash feldspathization.Geological characteristics of rare earth elements in quartz and pyrite of the Liubagou gold deposit show that the early ore-forming fluid(K-feldspar) is hypothermal and reductive,and that the ore-forming fluid temperature decreases gradually.The Eu positive anomaly of quartz and pyrite is an important typomorphic characteristic for exploring the quartz and K-feldspar vein type gold deposits,and the Eu positive anomaly is proportional to ore-bearing potential.The middle and east parts of No.313 vein in the Liubagou gold deposit are the key prospecting areas.It is very possible to find the quartz and K-feldspar vein type gold deposit in the deep region. |
