摘　　要：红泥坡铜矿位于四川拉拉铜矿田南部,主要赋存于古元古河口群的钠质火山岩系中,为与河口群火山喷发作用有关的火山-沉积变质型铜矿床,在分布上具有多层、成群及成带的特点。矿体呈似层状、透镜状产出,常见膨胀、尖灭再现及分叉复合等现象,主要围岩蚀变为黑云母化、硅化、碳酸岩化及绿泥石化等。矿床的形成主要受地层、岩体及构造因素控制,尤其断层与矿化关系密切。Hongnipo copper mine is located at the southern section of Lala copper ore belt. The copper mine associated with iron oxide which is related to the volcanic eruption of Hekou Group,and occurs in the sodic volcanic rocks series of the Hekou Group in Proterozoic. The ore body is distributed as multi-layers,clustering and banding,and hosted in stratoied and lenticular structure. Inflation,pinching and recurring,and branching and compounding are common in this deposit. The primary wall rock alteration includes biotitization,silicification,carbonatization and chloritization. The analysis shows that the ore deposit is controlled by the factors,such as layering and structure. Especially,the faults in the ore area are closely related to minetalization.
