摘　　要：蔚山铁铜矿位于安徽省无为县,是近年庐枞矿集区发现的新类型矿床,矿体主要赋存在石炭系黄龙组、船山组透辉石矽卡岩中,呈层状产出,主要矿石矿物为黄铁矿、磁铁矿等,少量黄铜矿,脉石矿物主要为方解石、透辉石等,矿床成因为矽卡岩型铁矿。从目前施工钻孔分析,形成矽卡岩的侵入岩体主要为花岗斑岩,结合地磁异常推断深部可能有规模更大的岩体,因此区内存在寻找(层控)矽卡岩型铁(铜)矿的较大潜力。Situated in Wuwei County of Anhui Province, the Weishan iron-copper ore deposit is a new type of deposit found in the Lu-Zong ore deposit cluster in recent years. The bedded ore body mainly occurs in Carbonaceous Huanglong Formation and Chuanshan Formation of diopside skarns, and consists of major ore minerals of pyrite and magnetite, and minor ehalcopyrite, and of major gangue minerals of calcite and diopside. Borehole analysis indicates that the intrusion is granite porphyry that has formed the skarn, and geomagnetic anomaly implies that there possibly exists a bigger intrusion in the deep. So it is still prospective to find stratabound skarn iron （copper） ore deposit in the area.
