3D Inversion of Magnetotelluric Data Applied to Exploration for Natural Resources

Magnetotellurics (MT) is a geophysical method that uses naturally occurring electric and magnetic fields to map variations in electrical conductivity in the deep Earth. Modelling MT data is computationally intensive, especially the 3D modelling algorithms.<p><p>The Centre for Exploration Targeting has an active programme of MT surveying as part of on-going research on regional mineral prospectivity.  This work is funded by the WA Government’s Exploration Incentives Scheme and the Federal Government’s Science and Industry Endowment Fund (SIEF)  Recently proposed regional-scale exploration models emphasize the role of structures in the deep crust and mantle as conduits for metal-bearing brines and magmas.  These are detectable using MT.  The proposed project is to continue the 3D MT modelling work associated with these projects with the work now involving one additional research-only academic and 3 Ph.D students.
