摘　　要：自20世纪50年代河南滦川钼(钨)矿床的发现,经几十年勘查研究和对区域水沉积物测量的资料分析,各构造单元元素丰度、富集系数和富集分布特征表明,区内富集元素为Mo、W、Au、Ag、Pb、Cu、Bi,尤其是Mo、W是区内重要的成矿元素处于中朝板块南缘的东秦岭—大别山钼(钨)矿带,是我国重要的钼(钨)矿带之一。研究表明,主要钼矿床属斑岩型,其次为矽卡岩型、脉型。成因多与中生代花岗质斑岩有关。文章着重对大别地区矿化中酸性小岩体地球化学特征进行讨论,以期为在该区普查找矿起到借鉴作用。The Luanchuan Mo(W) deposit has been discovered since 1950s ,after several decades of investigation and research with the analysis of the data about the measurement of regional water sediment,we have concluded from the elements abundance,enriching coefficient and enriching distribution characters of each tectonic unit that Mo,W,Au,Ag,Pb,Cu and Bi are enriched in this area,especially Mo,W elements as significant ore-forming elements are located in East Qinling——Dabieshan Mo(Wo) metallogenic zone,which is on...
