| 摘 要： | 二郎坪群位于北秦岭造山带中,在二郎坪群这套火山—沉积岩系中,含有在河南省占有重要地位的铜多金属矿。文章通过对二郎坪群的沉积建造特征、变基性火山岩的形成环境和岩浆来源特征的研究,认为二郎坪群形成于弧后盆地环境,其盆地规模和岩浆来源在盆地东西方向上存在差异,而铜多金属矿床成矿作用与二郎坪群的形成环境和变基性火山岩岩浆来源有着紧密的内在联系。二郎坪群弧后盆地在海底喷流作用下形成了不同成矿元素组合的铜-锌型和铅-锌型两种矿床类型。

| Abstract: | Erlangping group,which lies in northern Qinling orogenic belt,is a set of volcanic-sedimentary rock series which host an important copper polymetallic mineralization belt in Henan province.After the research on sedimentary characteristics,forming environment and source of magma of metabasite,it is considered that the volcanic-sedimentary association of Erlangping Group was formed in the back-arc basin,There are some differences in the scale of the back-arc basin of Erlangping and its magma source in east and west,while the mineralization of copper polymetallic deposit is closely associated with the forming environment of Erlangping Group and the magma source of volcanic metabasite.Copper zinc type and lead zinc type deposits with different ore elements were formed in Back arc basin of Erlangping Group by sea bottom spout. |
