NAM69XXX: Copper with Cuprite on Quartz

Floating group formed by well-defined Copper crystals, with their characteristic coppery color, but also with reddish tones due to the presence of Cuprite. Their arrangement is very airy, with arborescent growths of curious architecture, supported by a Quartz matrix. The specimen, which comes from the Santiago Ugido collection, is of notable quality for the deposit from which it originates. The Herrerías mines lie in the western sector of the Iberian Pyrite Belt, a major Paleozoic (Devonian–Carboniferous) volcanogenic massive sulfide (VMS) province. Mineralization is hosted by volcano-sedimentary sequences, forming stratabound ore bodies and associated stockwork zones, dominated by iron and copper sulfides with subordinate lead and zinc. Variscan deformation and later supergene processes strongly influenced the paragenesis and the development of some secondary minerals.

Specimen size: 8.1 × 6.1 × 3.6 cm = 3.19” × 2.40” × 1.42”
