　　通过对帕奔金矿床地表及其深部地球化学场特征的研究及分析，总结了该区地质地球化学异常模式，认为可根据水系沉积物及岩石地球化学异常和地质特征来圈定找矿靶位。Au、Hg、As、Tl四个元素的异常吻合性好，Au异常连续性好、宽度大、强度高，浓度分带特征明显,可作为本区寻找金矿的直接标志，Cu、Pb、Zn、Mo、Ti、Mn、Ni、V等元素异常可作为寻找金矿的间接标志； u与As、Hg、（Sb、Tl）密切相关，与其它元素不相关或相关性很低。根据异常特征和构造分布特征可确定矿体、矿化体的存在，还可以确定深部矿体、盲矿体的分布。笔者还总结了该区地球化学异常模式，对下步找矿方向进行了初步探讨。认为，1）矿区Ⅴ号主矿体向南、北两侧沿走向延长方向，注意向南的砂岩层位下的灰岩中的金矿体延伸，矿区其它矿段在开展岩石地球化学测量基础上进行钻探深部找矿。2）矿区外围Au、Hg、As等组合的水系和土壤异常中，北东部的单Hg异常规模大、强度高，可先开展土壤或岩石剖面测量，根据地球化学异常模式指导下步找矿工作。

The geochemical anomaly model of the Phabon gold deposit in Laos was Summarized based on the Geochemical field measurements and analysis of surface and deep geochemical characteristics. The our elements, Au,Hg,As and Tl anomaly coincide well. Au anomaly has Good continuity with big width and high intensity, and the thickness belt is obvious, which could be a direct mark for gold hunting. The Cu、Pb、Zn、Mo、Ti、Mn、Ni、V element anomaly would be the indirect sign. The U is closely related with As、Hg、(Sb、Tl), and no relativity with other elements. The expecting targets determined with the stream sediment survey anomalies and geological con-dition was proved by the drilling that there are gold ore bodies there. The geochemical model is of guide signifi-cance also. It is suggested that: 1) the Ⅴ Gold Ore Body maybe extend along trend with north-south direction in-to the limestone under the sandstone. 2) pay more attention about the Au, Hg, As element. The single Hg element anomaly scale is big with high strength, which propose soil or rock profile survey should be carried out. It would guide us the next work.
