甘肃省肃北县平头山井铜多金属矿地质特征与控矿因素分析

Geological characteristics and ore-controlling factors of copper polymetallic ore in Pingtoushan well,Subei County,Gansu Province

平头山井铜多金属矿位于马鬃山地块,是受构造控制的岩浆期后热液型铜多金属矿。铜矿(化)体赋存于剥离断层下盘敦煌岩群C岩组的方解黑云石英片岩和阳起片岩中,受剥离断层及NNW向断裂控制,与铜矿化关系密切的蚀变主要是硅化、黄铁矿化。

Pingtoushan well copper multimetallic ore is a post-magmatic hydrothermal copper multimetallic ore controlled by structure and located in Maomangshan block.The copper（chemical）body is stored in the calcite black quartz schist schistosite from the C rock group of the Dunhuang rock group under the divestiture fault,controlled by the divestiture fault and the NNW direction fracture.Corrosion closely related to copper mineralization is mainly silicification and yellow iron mineralization.
