摘　　要：在江西省九江市武宁县大湖塘地区，江西省地质矿产勘查开发局下属的916大队和赣西北大队探明了钨金属量达超大型的钨钼铜等多金属矿田。使用重力三维反演方法以及RGIS2012三维反演软件，对剩余重力异常所反映的地下0～12km深处的岩体形态、重力异常剖面特征以及与含矿体的关系等展开研究。本文采用重力异常和矿产地质相结合的方法对武宁矿集区进行系统的研究与总结，得出剩余重力低异常和其它地质方法可以预测和研究燕山期岩体的深度和含矿性，并对江西省武宁大湖塘地区的岩体作出了合乎地质情况的三维形态研究。At the Da Hutang area Wuning county, Jiujiang of Jiangxi Province, the 916 geological bri- gade and Northwest Jiangxi geological brigade under the Geology and Mineral Exploration and Develop- ment Bureau of Jiangxi Province, proved tungsten -molybdenum -copper polymetallie ore field which might contain ultra -large amount of tungsten metal. Using gravity 3D inversion method and RGIS2012 3D inversion software, study was made on the rock mass morphology, the gravity anomaly profile char- acteristics and the relationship between the ore - bearing bodies, in the depths of underground 0 - 12kin. This research combined with mineral geology results could be used in prediction and research of the ore body depth and ore -bearing potential for Yanshan period rock. A research on 3D morphology of rock mass in the Da Hutang area of Jiangxi Province was also made, conforming to geological condi- tions.
