Application of apparent density inversion method in the East China Sea and its adjacent area
视密度反演在东海及邻区重力异常解释中的应用

The principal of apparent density inversion method based on potential field separation is introduced.This apparent density inversion method is applied to process the gravity anomaly data in the East China Sea and its adjacent area,and the density anomaly results are presented.The interpretation shows that the apparent density inversion method has a good ability in distinguishing the regional faults in the research area such as Tanlu Fault,Jiangshao Fault and the concealed Dongyin-Haijiao Fault.The apparent density slice maps in different depths help us to understand the dimension and developing depth of these faults.In the Trench-Arc-Bain area where the topography and tectonics are very complicated,the apparent density inversion method can be used to do deep geological structure study.It can indicate the distribution of compensative mass and the undulation of Moho discontinuity.
