Geophysical characterization of the Cercal Paleozoic

The Cercal Volcano-Sedimentary Complex (Cercal VSC) structure is the westernmost sector of the Iberian Pyrite Belt (IPB) giant metallogenic province and was explored since Roman times for volcanogenic massive sulphides (VMS) and Fe Mn (Ba) deposits. However, presently only a single deposit is known, the Salgadinho Cu-Ag-Au …
