摘　　要：通过老挝万象市塞塔尼县钾盐矿床详查工作,物探测量选择重力测量、综合测井、采样分析等方法取得了良好的效果。重力测量圈定2类18块成矿有利靶区;综合测井确定矿体准确位置和厚度;采样计算矿体密度;实验室分析计算矿体品位。展现了此方法在该区找矿上的应用成果及钾盐矿床的矿体特征,为钾盐矿体资源(储)量的估算提供了重要的基本参数和依据。Through the detailed investigation of the potash deposit in Seitani county,Vientiane city,Laos,the methods of gravity survey,integrated logging,sampling and analysis have been selected for geophysical survey,and good results have been obtained.Gravity survey delineated 2 types of 18 favorable target areas for mineral-ization,comprehensive logging was used to determine the exact location and thickness of orebody,sampling was used to calculate the density of orebody,and laboratory analysis was used to calculate the grade of orebody.The application results of this method in prospecting in this area and the characteristics of potash ore body are pre-sented,which provides important basic parameters and basis for the estimation of potash ore body resources(storage).
