摘　　要：运用MineSight软件对赣中西部金滩岩体峡里铀矿进行了三维地质建模。三维地质模型展示了岩性、构造、剖面、矿化域等地质信息,估算出的地质资源储量、平均品位与原地勘察报告结果基本一致。模型总体精度较高,并且最大限度地满足了市场的需要。峡里铀矿三维建模验证了以往地质报告的可靠性,加深了矿床找矿认识,为后续勘查工作布置、靶区圈定以及其他矿种找矿等地质工作提供了更为精准科学的依据。Using MineSight software,a three-dimensional geological modeling of the Xiali uranium deposit in the JintanPluton in central and western Jiangxi was carried out.The three-dimensional geological model displays geological information such as lithology,structure,profile,and mineralized domains.The estimated reserves and average grade of geological resources are basically consistent with the results of the in-situ survey report.The overall accuracy of the model is high,and it meets the needs of the market to the greatest extent.The three-dimensional modeling of the Xiali uranium deposit verified the reliability of previ⁃ous geological reports,deepened the understanding of ore deposit prospecting,and provided a more accu⁃rate and scientific basis for subsequent exploration work layout,target delineation,and other mineral pros⁃pecting work.
