| 中文摘要: |
| 老挝Phu Kham铜金矿为大型斑岩-夕卡岩型铜金矿床，地处老挝川圹省西南部。通过野外地质调查和室内工作，研究了Phu Kham铜金矿床形成的地质背景、矿床地质特征、成矿时代、找矿模式及成因类型。结果表明：铜金矿容矿岩系为石炭-二叠系碳酸盐岩、火山碎屑岩、夕卡岩及斑岩脉；矿石矿物主要为黄铁矿、黄铜矿、蓝铜矿、斑铜矿及孔雀石等；矿床成因为斑岩-夕卡岩型，成矿时代为晚石炭世—早二叠世。预测在Phu Kham矿区及长山成矿带内具有寻找大型-超大型铜金铁锡矿床的潜力。 |
| 英文摘要: |
| PhuKham Cu-Au deposit is a large porphyry-skarn type Cu-Au deposit in southwest Xiangkhouang Province at central Laos. Field and Lab investigation and research reveal the geological and metallogenic background, characteristics of the metallogfewnic period, prospecting model and genetic type of the deposit. Host rock of the deposit includes Carboniferous-Permian carbonate rocks, volcanic clastic rocks, skarn and porphyry dyke. Pyrite, chalcopyrite, azurite, bornite and malachite are the main ore minerals. The deposit was formed in Late Carboniferous epoch-Early Permian epoch. According to its metallogenic model the Phu Kham deposit area and Changshan metallogenic belt are potential for prospecting large-super-large Cu-Au-Fe-Sn deposits. |
