Geosoft will be attending the 35th Annual Convention of the Association of Exploration Geophysics, in New Delhi, the week of October 3-5, 2013. 

At this presentation, Interpretation of magnetic data at low magnetic latitudes using Magnetization Vector Inversion, Geosoft's Ash Johnson, and Telma Aisengart, will review the MVI method and how the availability of cloud computing resources has made this a very quick and practical tool. The talk will illustrate the practical use of MVI with examples from the Quadrilátero Ferrífero (Iron Ore Quadrilateral) in the state of Minas Gerais, Brazil. The magnetic data over this area exhibit typical patterns seen in low magnetic latitudes. We will show that use of the analytic signal technique makes a significant improvement in the 2D interpretation and correlation with surface geology. They will also compare traditional susceptibility inversion in the 3D case with the MVI technique and show how MVI is the preferred method for 3D inversion at low magnetic latitudes.
