前河金矿位于华北克拉通南缘熊耳山地区,属于典型的构造蚀变岩型金矿。矿区出露的地层主要为古元古界熊耳群鸡蛋坪组流纹斑岩、英安岩及安山岩和马家河组安山岩、杏仁状安山岩夹凝灰岩。区域构造以近EW向断裂为主,局部有NE和NNE向断裂发育。区内中生代岩浆活动强烈,形成五丈山
The Qianhe gold deposit is located in the Xiong’ershan area on the southern margin of the North China Craton and belongs to the tectonic altered rock type gold deposit. The strata exposed in the mining area are mainly the rhyolite porphyry in the Eupatorian Formation of the Xiong’er Group in the Paleoproterozoic, the dacite porphyrite of the dacite and the dacite andesite and the Majiahe Formation, and the almond-shaped andesite dacite tuff. The regional structures are mainly near EW faults and NE and NNE faults are locally developed. The Mesozoic magmatic activity is intense in the area, forming Wuzhang Mountain
