THE REASERCH ON GENERALIZEAL JOINT INVERSION METHOD USED TO INVERSE MAGNETIC AND DENSITY INTERFACE

With the development of regional geophysics work, it has been become one important aspect aspect to reverse the interface for geophysist. Many geophysists in our country and abroad have been taken part in the reasercher on this field, in which better ones are interation and direction methods, such as the methods of mass compression, method of U function, method of parker, and so on. They have multiple and unstable solution like othar inversion methods.This paper searches and discusses the method of generalized joint inversion and its uses in inverse interface when gravitational and magnetic anomalyes have the same source. It has been verified in model experiment that this method has some advantages in abating ununigue solution, inhancing solution stability arid gaining the model, and it is one promising inverse method.
