摘　　要：对太行山南段铜矿化带成矿地质背景、甘陶河群火山岩铜矿化特征及控矿因素进行了翔实的研究。结果认为,宏观上,太行山南段铜矿化带受裂陷槽和变质核杂岩构造体系的控制。铜矿化的产出受层位、岩性、韧脆性断裂、围岩蚀变等因素的联合控制,矿体呈脉状、似层状产出,矿石类型以细脉浸染状为主。进一步找矿方向重点应是深部找矿,工作方法采用综合找矿,主要手段为物探电法和钻探工程。Through the in-depth research on regional geological background and copper ore exploration, it is included that the copper ore belt in Gaitao River area is controlled by fracture depression and the structure system of metamorphic core complex. The occurrence of the copper mineralization was jointly controlled by the factors such as stratum, lithology, brittle-ductile fracture and country rock alteration etc. , with orebodies occurring in vein or layer, being mainly veinlet-disseminated ore. The further exploration should be focused on prospecting in the deep part with comprehensive prospecting methods, using electric method or drilling project as major tools.
