Geophysics mineral software modelling
Various techniques are available to locate magnetic bodies buried in the subsurface, particularly when it comes to mining explorations. Existing techniques have restrictions and problems, such as only working with profile data, being restricted to a specific source type, or failing in the presence of remnant magnetization (magnetization which some rocks possess even in the absence of a geomagnetic field).
A Wits researcher has come up with new algorithms better to interpret already available magnetic data. In particular, these equations more accurately determine the subsurface location, geometry and depth of magnetic bodies from aeromagnetic data. Thus, the algorithms make it easier for geophysicists and geologists to find mineral deposits of economic value.
The developed algorithms are not constrained by some problems that exist with existing techniques, as set out above.
