Exclusively available in Geosoft VOXI Earth Modelling, Magnetization Vector Inversion (MVI) solves the challenge of varying direction of rock magnetization to provide a more reliable representation of subsurface geology.

  • Gain greater insight in the interpretation of magnetic data.
  • Get a more accurate picture of subsurface rock magnetization.
  • Increase modelling accuracy in regions of low magnetic latitude, anisotropy and remanent magnetization. 
  • Interpret and define drill targets, deeper undercover, with
    greater confidence.

Find what's hidden, faster

As exploration moves deeper undercover, MVI is an advanced geophysical modelling technique that allows explorationists to visualize what’s hidden more quickly and accurately.

MVI is useful for all exploration projects. It is essential when modelling low magnetic latitudes, where magnetic interpretation is most challenging.

The Advantages of MVI FOr exploration 

Optimised performance

Increase model accuracy

Magnetization Vector Inversion improves modelling results by eliminating erroneous assumptions about magnetization, and delivering geophysical outcomes that fit geological expectations.

MVI models the magnetization vector that gives rise to total magnetic field (TMI) data, and provides a more complete exploration model aligned with the size and orientation of magnetic bodies. It solves for both the magnitude and direction of rock magnetization, making MVI more generally applicable than traditional susceptibility modelling.

Gain deeper insight

MVI is most effective in situations where geological processes or geophysical effects, such as deformation, anisotropy, remanent magnetization and high susceptibility, alter magnetization direction. The ability to account for these effects can make the difference between seeing and missing geological structure associated with mineralization in challenging subsurface regions.
