摘要:

为了提高老挝爬奔金矿找矿效果,应用原生晕分析得出爬奔金矿含矿流体来源于矿脉南部,同时通过对5条平行矿体雁列式空间分布特征、V-1号主矿体空间分布特征和控矿显微构造进行分析,得出爬奔金矿体具有向南东侧伏的规律。通过研究爬奔金矿V-1号主矿体纵投影图及构造叠加晕特征,发现“前尾晕共存”现象,说明存在多期次成矿活动,矿体剥蚀程度较小,且深部延伸较大,可能存在盲矿体;通过分析前人对爬奔金矿区成矿期流体包裹体的测温结果可知,均一温度变化部分成矿温度大于300 ℃,推测矿床成因可能与岩浆热液有关,含矿流体应与岩浆、大气降水和地表水等均有关联;在深部500 m钻孔中可见含雄黄、雌黄的高品位原生矿石,认为爬奔金矿深部具有寻找硫化物型金矿体及富矿脉的潜力。

Abstract:

Phabon gold deposit is located in Phabon Village,50 km north of Luang Prabang City,Laos.Six gold orebodies were discovered in Phabon gold deposit,which has reached the large-scale gold resources according to the current level of exploration.Phabon gold deposit is in the “Sanjiang” metallogenic belt in Yunnan Province,which has the favorable metallogenic conditions.It is hosted in the Permian limestone and controlled by a NW-trending fault system.There are three types of primary ore and the ore-forming period is disseminated type,breccia type and auriferous calcite vein.The breccia type is with the highest grade,followed by disseminated type,and auriferous calcite vein with the lowest grade.This study explores the phenomenon of “coexistence of front and tail halos” by studying the vertical projections of the V-1 main orebody and the structural superimposed halo characteristics,which indicates that there are multiple stages of ore-forming activities,and the degree of denudation of orebodies is small.The extension is large and there may be blind orebodies in depth.At the same time,the anomalous concentration center of different ore-forming elementis distributed in the south-east direction,so it is speculated that the migration process of ore-bearing hydrothermal fluid alonging the tectonic fracture is from bottom to top and from south to north,which provides geochemical basis for the determination of lateral law.The spatial distribution characteristics of the different level of the V-1 main orebody and a series of parallel veins distributed by the left geese,and the ore-controlling microstructures shows that the Phabon gold ore vein has the rule of the lateral trending towards the southeast side.In addition,through the analysis of the pre-existing temperature measurement of the fluid inclusions in the metallogenic period of the Phabon gold mining area,parts of the mineralization temperatures are higher than 300 ℃.It is speculated that the genesis of the deposit may be related to magmatic hydrothermal fluid,and the ore-bearing fluid may be related to magma,atmospheric precipitation,surface water,etc.At the same time,high-grade native with realgar and orpiment can be seen in the 500 m depth of borehole.All of them are believed to have the potential to find sulphide-type gold orebodies and rich veins in the depth of the Phabon gold mine.The above conclusions provide theoretical guidance for prospecting and increasing gold resources in the depth and explorating parallel orebodies in the future.

Key words: magmatic hydrothermal fluid, ateral trending, deep explorating prospection, primary ore, Primary hole, Phabon gold deposit, Laos
