| [摘 要]果园铜矿位于云县—景谷—景洪Cu、Sn多金属成矿带，澜沧江火山弧与兰坪—思茅弧后盆地的过渡地带。矿带内已发现一处大型（思茅大平掌）、多处中小型（景洪三达山、景东文玉、景谷民乐、岔河、云县铜厂沟、查家村等）火山热液型铜矿床。矿区成矿条件优越，含矿地层为上三叠统小定西组(T3xd）。含矿岩性为安山岩、玄武岩、安山玄武岩。矿体在空间上受控于北西向、北东向断裂构造破碎带。本文总结其成矿地质特征，找矿标志，对矿区找矿潜力进行分析，认为本矿区及外围工作程度较低，通过进一步工作，具有找到中—大型铜矿床的远景规模。 |

| Abstract: The Guoyuan copper ore deposit is located in the Yunxian-Jinggu-Jinghong Cu-Sn polymetallic ore belt, the transition zone between the Lancangjiang volcanic arc and the Lanping-Simao back-arc basin, where a large-scale (Simao Dapingzhang) and several medium- to small-sized (Jinghong-Sandasa, Jingdong-Wenyu, Jinggu-Minle, Chahe, Yunxian-Tongchangou,Chajiacun) volcano-hydrothermal-type copper deposits have been found. The ore-bearing stratum is the upper Triassic Xiaodingxi Formation, and the ore-bearing rocks inlcude andesite, basalt and andesite-basalt. The ore bodies are controlled by NW- and NE-trending structural fracture belts. This paper summarized the ore-forming characteristics and prospecting indicators, and analyzed the regional prospecting potential. And we consider that the mine and its surrounding areas have been surveyed to a lower degree, and medium- to large-sized copper deposits can be expected to be discovered by further exploration. |
