On the basis of crustally contaminated felsic and mafic rocks, the volcanism is interpreted to have occurred in a ...

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 ...
