Zusammenfassung

The seafloor, hydrothermal deposits of Herrerías consists of a simple paragenesis of Fe-Mn oxides, base metal sulphides, native silver, baryte, siderite, jasper and gypsum (scarce). Its geotectonic setting corresponds to a positive "flower structure", of Upper Miocene age, within which the N-S the ore fluids. This the main channels for the emplacement of the ore fluids. This mineralized structure ha been formed according to a subvolcanic doming in a shear zone.
