Vanadinite cluster on sturdy matrix with some large, well defined crystals.
Vanadinite is a mineral belonging to the apatite group of phosphates. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of small red hexagonal crystals. An uncommon mineral, Vamadinite only occurs as the result of chemical alterations to a pre-existing material. It is therefore known as a secondary mineral. It is found in arid climates and forms by oxidation of primary lead minerals. Vanadinite is especially found in association with the lead sulfide, galena.
