摘　　要：自20世纪五十年代发现河南滦川钼(钨)矿床以来,经几十年勘查研究和对区域水系沉积物测量资料的综合分析,各构造单元元素丰度、富集系数和富集分布特征表明,本区富集元素为Mo,W,Au,Ag,Pb,Cu,Bi,尤其是Mo,W是区内重要的成矿元素。位于华北板块南缘的东秦岭-大别山钼(钨)矿带,是我国重要的钼(钨)矿带之一,钼矿床主要属斑岩型,其次为矽卡岩型、脉型,其成因多与中生代花岗质斑岩有关。本文着重对大别山地区矿化中酸性小岩体的地球化学特征进行总结和论述,以期为该区普查找矿起到借鉴作用。Since the 20th century, the fifties （tungsten） deposit was found in Henan, Sichuan , Luanhe molybdenum. After several decades of research and exploration of regional stream sediment survey data analysis, the tectonic units of the element abundance, enrichment factor and enrichment distribution shows that the enrichment of elements in this region for the Mo, W, Au, Ag, Pb, Cu, Bi, in particular, Mo, W is the region important ore - forming elements. North China plate is located at the southern edge of the East Qinling - Dabieshan molybdenum （tungsten） ore belt, is an important molybdenum （tungsten） ore belt, one of the main case of molybdenum porphyry deposit, followed by skarn, vein - type, its causes with Mesozoic granit- ic porphyry related. This article focuses On the areas of mineralization by geochemistry summarized in the Dabie Mountains acidic small rockbody and discussed with a view to learn from the area played a role in prospecting census.
