摘　　要：矿区处于博罗霍洛山主脊,属斑岩型铜钼矿床。斑岩体本身为矿体,钼矿在岩体内,铜矿在外接触带。通过矿区北部勘查地球化学工作表明,Mo、Cu、Pb、Ag、As原生地球化学异常规模大、连续性好,形态规则,梯度大。As、Sb、Ag具前缘特征。除Mo、Cu外,Pb、Ag具主成矿元素特征。原生异常纵向分带具轴向分带特征,分带序列有一定的典型意义。从地质、地球化学异常特征、小岩体地球化学特征以及金属预测资源初步计算认为该矿床很有远景。The ore area is located in the redge of the Boroholo mountain and is a porhry copper-molybdenum deposit.The porphyritic body itself is an ore body.The molybdenum ore is kept in rock body and the copper ore is found in an outside contact strip. The geochemical prospection of the Northern ore area indicates that the scale of the protogeochemical anomalous dimensions of Mo, Cu, Pb, Ag and As is very great and its contenuity is very good.It is also shown its shape is regular, and its steps (grades) are great. The As, Sb and Ag are provided with a front feature. Besides Mo and Cu, Pb and Ag have mineralization element features.A vertical zona-tion of proto-anomalies is of axial zonation features. The zonation alignment has typical significance. Based on the geoloical and geochemical anomalous features, the geologica features of small rock body as well as the calculation of metal forecasted resources, it is considered that the orebody is of bright prospects.
