Presented at the ASEG (WA Branch) "Geophysical inversion for mineral explorers" on 20140902. At Geoscience Australia, we service many applications, and modeling and inversion of geophysical data is in widespread use throughout these. We principally deal with the following data types: Gravity, Magnetics, AEM, MT, and Seismic.
