Multi-level Magnitometry Contact Problem at Kimberlitic Field

In magnetometrics, a contact problem is a problem when magnetic properties (magnetic susceptibilities) of a magnetized bodies (layers) are presumed known and it is necessary to find the outilines of their borders (contacts). Contact problems can be difficult due to solution non-uniqueness and non-linearity, and further complications arose when anomalous fields are small and noise could mask the useful signal, which is the case with kimberlite pipes. We demonstrated that our adaptive approach can yield satisfactory results and create three-dimensional, geologically sound model of the kimberlite field.
