帕奔金矿床赋存于古生界二叠系灰岩中及与之相邻的接触带上。矿床受NNW向脆性断裂的控制,区域内构造发育,成矿条件优越。在前人研究的基础上,以帕奔金矿床为研究对象,通过对矿区地质概况、金矿矿床的类型及特征等的研究,按照矿床矿体热液作用类型、矿体就位方式和地质环境可分为四类:构造蚀变岩型金矿、断层破碎角砾岩型金矿、热液充填碳酸盐脉型金矿、红土型或溶洞型金矿。总结出该区是以构造作用和围岩蚀变为主的控矿因素,且运用元素地球化学参数特征,以及地球化学异常组合的方法,获取了区域找矿标志,对以后该地区寻找金矿具有重要的指导意义。
帕奔金礦床賦存于古生界二疊繫灰巖中及與之相鄰的接觸帶上。礦床受NNW嚮脆性斷裂的控製,區域內構造髮育,成礦條件優越。在前人研究的基礎上,以帕奔金礦床為研究對象,通過對礦區地質概況、金礦礦床的類型及特徵等的研究,按照礦床礦體熱液作用類型、礦體就位方式和地質環境可分為四類:構造蝕變巖型金礦、斷層破碎角礫巖型金礦、熱液充填碳痠鹽脈型金礦、紅土型或溶洞型金礦。總結齣該區是以構造作用和圍巖蝕變為主的控礦因素,且運用元素地毬化學參數特徵,以及地毬化學異常組閤的方法,穫取瞭區域找礦標誌,對以後該地區尋找金礦具有重要的指導意義。

Phabon gold deposit hosted in Permian Paleozoic limestones and the adjacent contact zone. Controled by NNW brittle fracture,the deposit structure developed in the region,and the metallogenic condition was superior. On the basis of the previous studies on Phabon gold deposit,the mining geology,gold deposit type and characteristics of the deposit were analyzed. According to the type of hydrothermal ore deposit,ore body in place ways and geological environment,it can be divided into four categories,structural alteration type gold deposits,broken fault breccia type gold deposits,hydrothermal filling carbonate vein type gold deposits,and laterite?type/cave?type gold deposits. We summed up that the tectonization and wall rock alteration are the main ore?controlling factors of the area. Based on the element geochemistry parameters characteristic,we used geochemical anomalies combined method to get the regional ore indications,providing important guidance for exploration gold deposits of the area in future.
