Abstract
Summary
Recently, the interest in joint inversion of different geophysical data has been significantly increased. Not only the model constraint but also the constraint between different physical parameters should be taken into consideration in the inversion. Using a four-point difference cross-gradient constraint, a 2D joint inversion algorithm of MT and full-waveform seismic data has been developed. The synthetic experiments show promising results. The joint inversion is more valid than the separate inversion, significantly improving the accuracy of resistivity image and somewhat promoting the quality of velocity image.
