Published in 2017 at "Geophysical Prospecting"

DOI: 10.1111/1365-2478.12591

Abstract: The quantitative explanation of the potential field data of 3-D geological structures remains one of the most challenging issues in modern geophysical inversion. Obtaining a stable solution that can simultaneously resolve complicated geological structures is… read more here.
