Ore-controlling Factors and Prospecting Significance of Intrusive Rocks in South Shaanxi Qinling Orogenic Belt
-
摘要: 笔者厘定了陕南秦岭造山带侵入岩的演化序列，分析了侵入岩岩石类型、岩浆作用类型、岩体规模、成矿母岩元素含量等对成矿的控制作用。在总结侵入体与矿床（体）二者空间配置关系基础上，首次提出了岩体内部成矿、岩体边缘成矿和岩体外缘成矿等侵入体的3种成矿方式。其对深入研究侵入岩的成矿规律、指导找矿工作具有一定的理论和实践意义。Abstract: This paper determined the evolutionary sequence of intrusive rocks in south Shaanxi Qinling orogenic belt and analyzed the controlling factors of the rock type, the magmatic type, the mass scale and the element content of metallogenic rocks on the mineralization.On the basis of the relationship between ore-forming intrusions and ore deposits (bodies), the authors proposed such three metallogenic modes as intrusions in rock mass, ore-forming at rock mass margin and ore-forming at rock mass margin, which is of theoretical and practical significance for the research into the mineralization of intrusive rocks and the guidance of the prospecting work.
