Description

Vanadinite from Morocco. (4.6 cm across at its widest)

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are about 5400 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.

Vanadinite is an uncommon, but beautiful, reddish-colored lead chlorovanadate (Pb5(VO4)3Cl). Vanadinite has hexagonal crystals, a hardness of 3, and a nonmetallic luster described as adamantine or resinous.

The highest quality vanadinite is from Morocco in northwestern Africa. The sample shown above is Lower Jurassic dolostone covered with nice vanadinite crystals. The specimen comes from near Mibladen, Morocco.

Locality: Mibladen (probably from the A'hcif Mine (A'hcif Shaft), near the old mining village of Mibladen), ~15 km northeast of Midelt, eastern Khenifra Province, northern Morocco
