Mineral Specimen #4277 Hanksite
Searles Lake, San Bernardino Co., California, USA
Collected by Steve Pullman
A relatively large, crudely formed crystal of this rare Sulfate (or according to some, Carbonate. When I retrieved this from the flat it was stored in, it had quite a bit of white hydrated material on it. A good coating of silicon spray, WD40, took care of it. It should be stored in a sealed plastic bag if there is much humidity (which we definitely have in Michigan). The crystal is brown with a slight green tint and fairly clear, but there are pockets of clay inside. The overall color is due to the inclusion of clay. The surfaces are quite uneven and have a few small areas of cleaved surfaces. Also, there are quite a few internal cleaves.
