Geología y metalogenia del yacimiento de estibina-scheelita de "San Antonio" Alburquerque (Badajoz)

Abstract

The geological setting of the stibnite-scheelite "San Antonio" deposit is studied in this paper. The region consists of Lower Ordovician schists and graywackes, Ordovician to Silurian quartzites and carbonaceous schists, and Devonian carbonate rocks. Three tectonic phases and two fracture systems have been identified in the area. The mineralization was originated by hydrothermal solutions —scheelite being the first mineral to be deposited. The mine is located within an Hercinian Au-Sb belt which crosses the Iberian Peninsula from Oporto (Portugal) to Valdepeñas, in the Ciudad Real province (Spain).
