摘要
老挝班康姆铜金矿位于老挝西北部,受琅勃拉邦断裂带影响,在本区发育一系列次级断裂,矿体受NE―NNE向韧脆性剪切带控制,本文通过综合分析班康姆铜金矿床成矿地质背景、矿区地质特征、围岩蚀变特征及矿床成因等,认为班康姆铜金矿为构造热液叠加改造型矿床,具有较大的找矿潜力,并提出了对本区该类型金矿的找矿方向。
Pangkuam Cu-Au deposit is located in northwestern Laos.Due to the effect of Luang Prabang frac-ture zone,and a series of secondary fractures are developed in this area.The orebodies are controlled by NE-NNE-trending ductile brittle shear zone.Through comprehensive analysis of ore-forming geological back-ground,geological characteristics,wall rock alteration characteristics and deposit genesis of Pangkuam Cu-Au deposit,the authors believed that Pangkuam Au deposit was a tectonic-hydrothermal superimposition-transformation type deposit with great potential for prospecting.The authors also put forward the prospec-ting direction of the same type gold deposits in this area.
