Resumen

The Pb, W and Pb-W mineralizations described in this paper are situated 3-4 km east of Guijuelo, in the province of Salamanca. The host rocks are metasediments of the Monterrubio Fm., a rock assemblage occurrying in the schist greywacke complex (CEG), which underwent three Hercynian tectonic stages and one important late Hercynian fracturation. The Pb ores are vein-like and hydrothermal, the W ores are disseminated in calsilicate rocks; and the Pb-W ores, represented by La Tala or ebody, have a mixed origin, as hydrothermal Pb-rich solutions affected the stratabound W mineralizations already present in the CEG. Due to it, stolzite (PbWO^ made up most of the ore when the mine was in operation.
