云南易门县铜厂铜矿床地质特征与成矿规律

云南易门铜厂铜矿床位于扬子板块西南缘,处于昆阳裂谷武定—易门—元江裂陷槽中部。本文在总结前人研究工作的基础上,结合成矿地质背景,以铜厂矿区铅箐厂、栗粟、大尖山、新庄、铜厂等五个矿段为研究对象,从地层、构造、岩浆岩、围岩蚀变以及铜矿体的空间分布特征等方面,总结该矿床地质特征与成矿规律,指导今后的地质找矿工作。

Geological characteristics and metallogenic regularity of Tongchang Copper Deposit, Yimen, Yunnan Province

Tongchang copper deposit is located in the southwestern edge of the Yangtze plate and in the central part of Wuding-Yimen-Yuanjiang rift trough in Kunyang rift. Base on the previous researching achievements, and combine with metallogenic geological background. This study takes five ore blocks (Qianqingchang, Lisu, Dajianshan, Xinzhuang, Tongchang) of Tongchang mining area as objects. The geological characteristics and metallogenic regularity of the deposit are summarized from the aspects of strata, tectonics, magmatic rocks, wall rock alteration and the spatial distribution of copper ore bodies, and which can provides the next geological prospecting work.
