摘要
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.
