Resum
A preliminary investigation has been carried out by the Geological Survey of Spain, to evaluate mineral potentiality in the NW domain of the Iberian Pyrite Belt. Research focused on volcanogenic massive sulphide deposits of the so-called ¿Vocano Sedimentary Complex¿ from Lower Carboniferous. Four evidential maps (lithologic, gravity, magnetic and structural) were incorporated into a geographical information system and integrated in a mineral potential map, using weights of evidence and logistic regression methods. The goal is the application of a new methodology in this area that may facilitate mineral resources decision-making processes. Promising results were achieved concerning the use of such mathematical methods to applied geology.
