球坐标系下快速正演策略在重力异常剥离中的应用
Application of fast forward modeling strategy in spherical coordinates to gravity anomaly strippingn
摘要
Abstract
This study presents an efficient Tesseroid orthotropic modelling method for interface stripping,especially in large-scale and deep studies.By utilising a 3D Gauss-Legende integral(GLQ)method,combined with the equivalence of the kernel matrices,the computational time and memory requirements are significantly reduced.The method obtains the effect of deep interface undulations on the Bouguer gravity anomaly through the orthogonal evolution of the interface depth,which provides an effective means to accurately extract crustal and mantle structural information.In the application to the SCS and its neighbouring areas,the method successfully separates the gravity anomalies caused by the Moho surface and analyses the remaining anomalies after stripping.The results demonstrate that by eliminating the undulations of the Moho surface,the anomalous data can more precisely unveil the structural features of both the crust and mantle,offering robust substantiation for advancing studies into deep geological structures.The methodology presented in this paper introduces novel perspectives for the application and enhancement of gravity anomaly separation technology,while simultaneously augmenting computational efficiency.关键词
