The petrophysics shows that the mineralized zone is associated with high susceptibility values and was used as a constraint in the inversion of airborne...

..., and compare its magnetic signature with impact craters. Through the integration of geological mapping and petrography information, we propose a methodology for defining the susceptibility bounds for the inversion of magnetic data. The inversion results show a low susceptibility response at the central part...
