Wavellite

Wavellite

Discoverer of Wavellite, English physician William Wavel has the honor of its namesake. Wavellite is associated with crandallite and variscite as a seconday mineral in metamorphic rocks of low-grade as well as in phosphate deposits and rarely in hydrothermal veins. Wavellite is found worldwide in many localities. Readily dissolved by acids.

Wavellite from Union Carbide mine, Wilson Springs, Garland Co., Arkansas, United States

Wavellite
            from Union Carbide mine, Wilson Springs, Garland Co., Arkansas, United States

Large cabinet specimen filled with light grey to colorless hemispherical "crystal balls" of Wavellite. Each group is to about 2-3mm. A nice specimen for this mine which is probably unattainable. I believe it is all reclaimed. Specifically the specimen was found at the North Wilson mine, within the complex associated with alkalic intrusives about six miles from Magnet Cove. The mine is famous for its Sincosite, which at one time was maybe the second world occurence behind Sincos, Peru.
