There were a few geosoft authored papers published about 3 years ago at least one included an example of iri sharpening, search voxi iri on the names Macleod and Ellis. I'm not aware of fully 3rd party iri vs conventional inversion case studies but they may exist now, Google or check the geosoft website.
I've used the iri on voxi mag models and recommend it with a setting of 1 or 2 but you can test it up to setting 4. It does focus or shrink down modeled susceptibility to more discrete higher sus zones in some cases without a lot of time consuming inversion setting experimentation, the result can be quickly compared with a conventional voxi mag inversion, and/or with an mvi inversion with zero iri sharpening. You can then select what is thought to be the more realistic model based on any geologic, magnetic properties, borehole, mag profile, parametric model or other info.

Subject:[geonet] A scietific paper about Iterative Reweighting Inversion?
Hello, Is there any peer-reviewed publication about the IRIF (Iterative Reweighting Inversion) method used in VOXI Earth Modeling?
