面向深部矿产资源勘探的井中重磁三维交叉梯度联合反演
Cross-gradient joint inversion of 3D borehole gravity and magnetic data for deep mineral resources exploration
摘要
Abstract
The single borehole gravity and magnetic method has its limitations,and 3D inversion techniques often suffer from non-uniqueness.To address these challenges in deep mineral resources exploration,we propose a novel approach:borehole gravity and magnetic 3D cross gradient joint inversion.Initially,we couple density and magnetic susceptibility using cross-gradient functions,followed by joint inversion based on borehole gravity and magnetic multi-parameter data.This approach aims to reduce ambiguity and enhance the identification accuracy of deep mineral resources.The theoretical model and real data inversion results demonstrate that the borehole gravity and magnetic cross-gradient joint inversion offers high vertical res-olution,significantly improving the identification accuracy of deep mineral resources,particularly for effectively identifying deep concealed ore bodies.关键词
