Abstract
Summary
We developed a 3D frequency and time-domain parametric level-set AEM inversion code for multiple bodies with independent resistivities and applied a cooperative approach for spatially overlapping data sets. We tested the method on both synthetic and field data, and the synthetic results showed that the cooperative parametric approach recovered the most accurate inversion model. We then applied the method to overlapping AEM data sets at the Committee Bay greenstone belt in Nunavut, Canada to image linear thin dipping conductors where the dip information is crucial for the exploration program.
