Gravity Inversion Computations for Mass Anomaly Distribution of Regional Crust Based on Virtual Sphere Theory
Special Issues Editor (Nottingham Tent University, United Kingdom (Great Britain))
Based on the earth's geophysical structure, the point mass method is used to compute the inverse of the regional crust mass distribution. The earth is divided into two parts: the main body that is composed of several homogeneous concentric layers, and the abnormal mass in the regional crust. We calculate the gravity anomalies observations by the earth's gravity model with high accuracy and order. Then the point-mass model is used based on virtual sphere theory to simulate the experiments. In addition, mass depth is set to within 20km and the inversion region is less than observation area. Numerical inversion results show that there is strong relationship between the mass anomaly distribution of regional crust and the gravity anomaly on the surface.
