#51824

Availability: Sold

Locality: Ford mine, Mammoth Tiger Extension, Tucson Wash, Mammoth Mining dist., Pinal Co., Arizona, United States
Formula: Pb₅(VO₄)₃Cl
Size: Cabinet 17x15x14cm
Tagged: vanadium

This is a LARGE specimen. It is a textbook example of vein with open fracture mineralization. The opening is 3cm wide at the center and is lined with beautiful bright to dark orange Vanadinite crystals to 2mm. There are likely other exotic minerals in the fracture and matrix. Beneath the Vanadinite is a layer of black Mottramite. The opening was likely creating by hot, acicidc solutions which dissolved and etched out the Quartz along the fracture after which vanadium minerals were deposited and crystallized. A great educational specimen for economic geology and ore mineralization. A classic locality.

May cost extra to ship.

Availability: Sold

Locality: Old Yuma mine, Pima Co., Arizona, United States

Tagged: vanadium

An excellent specimen of Vanadinite. These crystals are dihexagonal prisms. The larger crystals which are up to 3mm have 12 prism faces - first and second order faces. With twelve faces, the prisms look almost round. Some of the smaller crystals are ordinary hexagonal prisms. These have a good transulcent orange-red color and are highly lustrous.
