通过分析江西省已知花岗岩体的物性、海拔、重力异常等特征,总结岩体与各种特征的对应关系.运用多尺度剩余重力异常半极值圈定岩体边界,并结合三维人机交互反演岩体隐伏部位的空间特征.最后,通过两个1∶5万工作区验证圈定方法的实用性和有效性,为后续隐伏岩体圈定工作提供可靠的依据. By analyzing the characteristics of the known granite bodies in Jiangxi Province, such as the characteristics of anomaly, elevation and gravity anomalies, the corresponding relationship between the rock mass and various features is summarized.The boundaries of the rock mass are delineated by the multi-scale residual gravity anomalies and the 3D- The spatial characteristics of the concealed parts of the rock mass.Finally, the practicality and validity of the delineation method are verified by two 1: 50000 workplaces, which can provide a reliable basis for subsequent concealed rock mass delineation work.
