  • GIS-based mineral prospectivity mapping using machine ...

    1. Introduction. Mineral prospectivity mapping (MPM) is a multicriteria decision-making task that aims to outline and prioritize prospective areas for exploring undiscovered mineral deposits of the type sought (Carranza and Laborte, 2015, Yousefi and Carranza, 2015b).This task is challenging, because mineral deposits are end-products of complex interplays of ore-forming processes that leave ...

  • From Predictive Mapping of Mineral Prospectivity to ...

    The latter is considered in one‐level prediction because indices of prospectivity (e.g. integrated Bel) tend to lack correlation with presence/absence of mineral deposits, although locations at/around prospects generally coincide with higher indices of prospectivity compared to locations away from mineral deposits (cf. McCammon et al., 1994). However, because those two assumptions in OLP are ...
