Metavauxite : Fe2+Al2[OH|PO4]2 · 8H2O | |
|
Siglo Veinte Mine (Siglo XX Mine; Llallagua Mine; Catavi), Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia 4.2 x 1.2 x 1.1 cm. Certainly the rarest member of the "vauxite" family, this is an hydrated, iron, aluminum, phosphate hydroxide.

Siglo Veinte Mine (Siglo XX Mine; Llallagua Mine; Catavi), Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia 2.9 x 1.5 x 1.2 cm. Metavauxite is the rarest of the related vauxite family members: paravauxite; metavauxite; and vauxite. It is a monoclinic dimorph of the already rare paravauxite, with clearly different crystal habit when seen in person. This is an aesthetic cluster of sharp crystals, from the type locality - surely, given its history in this ... |
