摘　　要：云南元江大明槽铜矿地处元江铜矿区,主要赋存于昆阳群落雪组白云岩及断裂构造中,矿体呈层状、似层状产出。根据前人的地质信息,在大明槽铜矿床详细工作的基础上,分析大明槽铜矿区地质特征,认为矿床的形成及空间分布受地层、岩性、构造及蚀变等多重因素控制,岩体提供主要成矿物质来源,断裂构造为矿化、富集提供通道和场所,并与地层控制着矿体产出的形态、产状及规模。Damingcao Copper Deposit is founded in the Yuanjiang copper deposit area in Yunnan, and the occurrence of the ore body is mainly in the cinerous dolomite rocks and the fault structure of Luoxue Formation of Kunyang Group. The orebody is in stratified and stratoid structure. Based on the detailed survey of Damingcao Copper Deposit, combining with the former exploration achievements, the geological characteristics are analyzed. The formation of the ore deposit and the spatial distributions are controlled by the strata, lithology, structure and wall rock alteration, etc. The primary material resource for the mineralization is provided by the rock body, and the channels and places are provided by the fault structure, and the shape, occurrence and scale of the ore body are controlled by the fault structure and the strata.
