| 中文摘要: |
| 老挝爬奔金矿床存在两类金矿化,即产于二叠系灰岩及其接触带上,受断裂构造控制的碳酸盐化低温热液型原生金矿化和产于凹陷地形中,与原生金矿化伴生的红土型金矿化。两类矿化在空间上紧密相关,空间结构自上而下为红土型金矿化和碳酸盐化构造蚀变岩型金矿。矿区土壤地球化学Au异常区、红土型金矿以及原生型金矿体常具"三位一体"的对应关系。 |
| 英文摘要: |
| Paben Gold Mine of Tianjin North China Geological Exploration Bureau which is occurred in the Permian limestone contact belt and belongs to epithermal type deposits controlled by the fault structure is found in northern Laos in recent years. This article studies the characteristics of Phapon laterite gold deposit, and analyze the ore-forming geological condition, points out that the formation of laterite gold deposits and native gold ore bodies formed in the Permian (P1) marine carbonate rocks is closely related in space from top to bottom. The mineralized space structure in this area is laterite gold deposits-local gold mineralization in the tectonic breccia cap-carbonate altered rock type gold. At last the article points out that the Au geochemical anomaly, the laterite gold and the original orebody often have a corresponding relationship, which can direct the prospecting and prediction of Phapon and similar mining area. |
