Although the ideal composition for vanadinite is Pb5(VO4)3Cl, phosphorus and arsenic often substitute for vanadium in the mineral’s crystal lattice. This results in a wide range of compositions which influence the specific gravity, color, and other properties. A solid solution series exists between vanadinite and and mimetite Pb5(AsO4)3Cl. Small amounts of calcium, zinc and copper…

Vanadinite is almost always a secondary mineral that forms in the oxidized zone above lead deposits. It is often found in oxidized veins containing primary and secondary minerals of lead. It is commonly associated with the oxidation of galena. The vanadium and chlorine are usually leached from the overburden by downward-moving waters. Vanadinite deposits are usually…

Vanadinite has a number of properties which, when considered together, usually make it easy to identify. It often occurs as brightly colored crystals that are usually short, tabular hexagonal prisms with a resinous to adamantine luster. It is most often bright yellow, orange, red or brown in color. It can also occur in globular forms and…

Vanadinite is a mineral composed of vanadium, lead, oxygen, and chlorine. It has a chemical composition of Pb5(VO4)3Cl. It is an important ore of vanadium and a minor source of lead. Vanadinite usually forms where lead minerals are oxidized, often in areas with an arid climate. It is not a common mineral, but it is found in small quantities…
