A 3D gravity data interpretation of the Matagami mining camp, Abitibi Subprovince, Superior Province, Québec, Canada

► Inversions of the gravity were realized in the Matagami area. ► The similarities between measured and calculated densities of rocks are exhibited. ► We built a 3D geodensity model which integrates densities and geological data. ► This reference model is integrated during the constrained inversion process. ► Resulting density model gives new insight for regional geological interpretation.
