Inversion of magnetometer array data by thin-sheet modelling

Wang, Lifan; Lilley, Frederick (Ted)

Description

A conjugate gradient relaxation method is employed in seeking an iterative solution to a particular 3-D electromagnetic inverse problem. The problem, which is non-linear, is that of modelling observed magnetic fluctuation response functions by a thin-sheet earth structure. The method optimizes data misfit and model roughness, and starting from a base model designed on known geology produces a series of improved models. Established thin-sheet algorithms are employed to compute the model...[Show more]
