Estudio mineralógico y químico de la asociación de sulfuros del yacimiento de Barquilla ( Salamanca, España )

An assemblage of rare sulphides which appears, locally in one of the mines microprobe. Cernyite-Greenockite-Tetrahedrite-Herzembergite and, in smaller quantity, Chalcopyrite, Ag-Bi-Pb bearing-sulfosalts, Galena and native Bi are locates at the Cassiterite-Montebrasite-Apatite-Albite-Q-Mica veins. In the country rock close to the veins, the most abundant sulphide is Chalcopyrite that forms part of different Fe-Zn-Cd-Cu-Sn bearing assemblages. Extensive sustitions are recognized in these minerals.
