甘肃省徽县同瓦沟铜矿地化特征及找矿方向

Geochemical Characteristics and Prospecting Direction of Tongwagou Copper Deposit in Hui County, Gansu Province

徽县同瓦沟铜矿大地构造位置处于昆仑-秦岭构造带秦岭褶皱带,大草滩-温泉华力西中期铜钼成矿带。区内地层复杂,构造运动及岩浆活动强烈,成矿地质背景良好,成矿条件有利,矿产丰富。文章在总结了成矿地质背景、地球化学特征的基础上,指出了找矿方向。

The Tongwagou copper deposit in Hui County is situated in the Qin Mountains fold belt of the Kunlunfu Qin Mountains tectonic belt, the dachaotan-wenquan variscan middle period copper-molybdenum metallogenic belt. The area is characterized by complex strata, strong tectonic movement and magmatism, good geological setting, favorable metallogenic conditions and abundant mineral resources. On the basis of summing up the metallogenic geological background and geochemistry features, the paper points out the prospecting direction.
