| 摘 要： | 通江岭铜钨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，其锆石U-Pb年龄为（143.31±2.70）Ma。通江岭矿区存在“上铜下钨铜”的矿化分带特征，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，找钨潜能大。

| Abstract: | 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 porphyry with zircon U-Pb age of (143.31+0.62) Ma. 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 silica-calcium interface formed during Ordovician-Silurian in the mining area have a great potential for tungsten exploration. |
