摘　　要：在全国矿产资源潜力评价工作中,如何在与侵入岩体成矿相关矿种中提取与导矿相关的导矿岩体与构造,提高重力资料的研究程度和应用水平,使重力勘探在研究多金属矿产的物质来源,示矿信息等诸方面起到有效的作用.本文从江西省德兴-婺源地区的15万重力测量资料研究中,通过使用RGIS2010重磁电数据处理软件对15万重力测量数据进行趋势分析,求取四阶趋势剩余场,通过对重力剩余场与地质构造,岩体的重力场体现,使用重力归一化梯度辅助反演解释岩体的空间形态特征,为金属矿产预测提供矿源物质提供来源通道和预测岩体深度提供依据.In the potential evaluation of the national mineral resource,how to extract the information of transmissive rock and rock construction from mineralization in connection with intrusive rock will play an important role in research of the origination and signal information of metal mine, which will also improve the application level of gravity. In the thesis, it finished fourth tendency analysis and inversion of full gradient of gravity anomalies for space feature of abnormal rock, which provide important basis for confirming resource of mineral substance and depth of buried rock.
