El Criollo Mine, Cerro Blanco pegmatite district, Tanti, Punilla Department, Córdoba, Argentina

StandardDetailedBy ChemistryMineral Photos (8)Search Google

Granite pegmatite quarry about 10km from town of Tanti. The blue cobaltoan genthelvite from here, now widely distributed in collections, is not from the pegmatite body itself, but from a younger vein of friable specular hematite that cuts across the pegmatite body.
