Miniera di Perdu Cara (Filoni di Perdu Cara-Santa Vittoria; Giacimento di Perdu Cara), Fluminimaggiore, Provincia del Sud Sardegna, Sardegna, Italia
Mining concession granted in 1959 to the company C. Castangia for cassiterite, lead, zinc, copper, cobalt, nickel, and iron minerals. The concession was taken over by the company "Surraco" in 1961 and by PROGEMISA in 1978, which until 1993 explored a large area (on the municipal territories of Fluminimaggiore and Gonnosfanadiga) including also the areas of Sa Menga, Bau Porcus, Genna Movexi, San Giorgio, Riu Mairu, Arcu Signor Melis, Genna S'Olioni, and Acqua Is Prunas.
The main NE-SW trending quartz vein, containing cassiterite and mixed sulfides, is located between Punta Santa Vittoria and Guardia Perdu Cara. The Perdu Cara deposit consists of a NEβSW trending swarm of upright and irregularly spaced veins hosted by very low-grade metasandstones within the foreland area of Sardinia. This vein system is ca. 1 km long and is vertically zoned from a lowermost barren zone containing a quartzβchlorite assemblage to a quartzβcassiteriteβchlorite zone and an uppermost quartzβarsenopyrite (PbβZnβCu sulphide) zone. These veins have thicknesses that vary between tens of centimetres and metres, reaching a thickness of ~1 m in the upper part of the system. The wallrock alteration in this area is also vertically zoned from a lowermost sericite + chlorite alteration facies, developed close to cassiterite veins, to widespread phyllic/argillic alteration associated with acid bleaching of rocks within the arsenopyriteβsulphide zone. Vein textures display bands and aggregates of cassiterite that alternate with several generations of milky to colourless banded and sometimes geodic quartz and chlorite (chamosite). Cassiterite crystals are millimetre to centimetre-sized, near transparent, idiomorphic, and commonly records growth zoning deο¬ned by small variations in Fe concentrations. Two generations of chlorite (chamosite) of similar composition are associated with this mineralisation: a dominant ο¬ne-grained variety that forms aggregates or bands associated with quartz and cassiterite, and a coarse-grained variety that forms millimetre-long radial aggregates close to contacts between the mineralised veins and surrounding wallrock. The cassiterite mineralisation grades upward to a sulphide ore dominated by arsenopyrite. As mineralisation shows a prevailing banded texture, consisting of millimetre-to decimetre-sized bands of arsenopyrite associated with white quartz, minor Cu-Zn-Pb sulphides, and pyrite. Arsenopyrite crystals are distinctly cataclased; chalcopyrite, sphalerite, galena and pyrite, also associated to successive generation of quartz, ο¬ll microfractures within arsenopyrite and white quartz.
