Vanadinite

A short overview of the mineral Vanadinite

Apatite Phosphate Group


Vanadinite [Pb5(VO4)3Cl] is related to Chlorapatite, the chlorine-rich member of the Apatite group [Ca5(PO4)3Cl]. In Vanadinite, lead (Pb) replaces the calcium (Ca) and vanadium (V) replaces phosphorous (P).

Vanadinite also forms a chemical solution series with Pyromorphite [Pb5(PO4)3Cl] and Mimetite [Pb5(AsO4)3Cl], Because P and arsenic (As) are easily interchangeable with V, Vanadinite may also contain these elements as impurites. When the ratio of V to As is 1:1, the common variety name Endlichite has been. However, Enlichite has been discredited by IMA (the International Mineralogical Association) and the varietal name Arsenatian Vanadnite is preferred.

Factoid : Vanadinite is 73.15% lead, Pyromorphite is 76.38 % lead and Mimetite is 69.61 % lead.

Vanadinite is usually bright-red or orange-red. It is commonly translucent, though the most prized specimens are transparent.
