《华南地区深部岩体圈定与形态研究》是中国地质调查局发展研究中心2010—2014年完成的项目成果简介。系统收集整理了华南多省重力、航磁、地质、化探及钻孔资料，采用滑动平均法分离区域与剩余重力异常，结合垂向导数、水平总梯度、解析信号、倾斜角等多种边界识别技术，并创新应用小子域滤波增强异常边界信息，共圈定各类侵入岩体1038个。在三维反演方面，提出“二维剖面反演+三维自动反演结果作为初始模型，再经三维人机交互精细调整”的技术路线，完善了RGIS三维重磁正反演软件及模型编辑程序，对102个重点岩体进行了三维形态反演，推断了其埋深、产状与空间展布。部分结果经钻孔验证效果良好。还开发了岩体三维形态信息展示软件，并将成果集成至地质云平台。该研究成果为华南地区深部找矿、成矿预测及地质构造研究提供了重要地球物理依据。
This project report (2010–2014) by the Development Research Center of China Geological Survey systematically delineated and modeled deep-seated intrusive rocks in South China using gravity and magnetic data. The team collected comprehensive geological and geophysical data across multiple provinces, applied moving average filtering for anomaly separation, and employed various edge detection techniques (vertical derivatives, horizontal gradients, analytic signal, tilt angle) enhanced by small-subdomain filtering. A total of 1,038 intrusive bodies were delineated. For 3D inversion, the project adopted a hybrid approach: using 2D profile inversions and 3D automatic inversion results as initial models, followed by fine-tuning through 3D interactive forward-inversion, facilitated by the developed RGIS software. 102 key rock bodies were modeled in 3D for depth, geometry, and spatial extent, with some results verified by boreholes. A 3D visualization and database system was established and published on the "Geological Cloud" platform, supporting deep mineral exploration and metallogenic prediction in South China.
