摘　　要：通江岭铜多金属矿区内矿体总体走向北东、倾向南东,呈似层状、透镜状产出于花岗闪长斑岩与茅口组碳酸盐接触带附近,矿石矿物以黄铜矿、白钨矿为主。区内成矿岩浆岩为花岗闪长斑岩。通江岭矿区存在“上铜下钨铜”的矿化分带特征,元素分带具有低温(前缘晕)–中温(近矿晕)–高温(尾晕)的特征,底部出现As、Sb、Hg等前缘晕元素,指示剖面下方还可能存在铜钨矿体,结合矿区石炭系、奥陶系碳酸盐岩与花岗闪长斑岩接触带或五通面、奥陶—志留系所形成的硅钙界面,认为找钨潜能大。The orebodies in the Tongjiangling copper-tungsten mining area generally strike northeast and dip southeast, and occur as layers and lenses near the contact zone between the granodiorite porphyry and carbonate of the Maokou Formation. The ore minerals are mainly composed of chalcopyrite and scheelite. The metallogenic magmatic rocks in this area are granodiorite por-phyry. Mineralization zoning in the Tongjiangling mining area is characterized by “copper in the upper part and copper and tungsten in the lower part”. The contact zone between Carboniferous and Ordovician carbonate rocks and granodiorite porphyry or the Wutong plane and the sili-ca-calcium interface formed during Ordovician-Silurian in the mining area have a great potential for tungsten exploration.
