Geophysical Modelling and Inversion


Geologically constrained inversion of geophysical data is a powerful method for predicting geology beneath cover. The cross seeks 3D physical property models that are consistent with the geology and explain measured geophysical responses. The recovered models can guide mineral explorers to prospective host rocks, structures, alteration and mineralization. This thesis provides a comprehensive analysis of how the University of British Columbia Geophysical Inversion Facility (UBC-GIF) gravity and magnetic inversions can be applied to subsurface mapping and exploration by demonstrating the necessary approach, data types, and typical results.
