Software development for a three-dimensional gravity inversion and application to study of the Border Ranges Fault System, south-central Alaska

Due to the importance of the Border Ranges Fault System as a petroleum province, our research tests several plausible models of earth structure by developing a novel, 3D inversion software package. The novel inversion approach involves directly modeling known geology, initially free-air corrected data, and revising a priori uncertainties on the geologic model to allow comparisons to alternative interpretations. This technique to evaluate 3D structure in regions of highly complex geology can be applied in other studies of energy resources.
