Copiapite [not analyzed] is a really weird highly hydrated iron sulfate that forms near the surface, in secondary oxidation zones of iron ore deposits. The iron that forms it usually comes from one or another of the sulfide minerals. It is remarkably light in the hand, and has a chalky texture. This large specimen came from the collection of Dave Stoudt, who was stationed in Poland for 10 years, and had the opportunity to obtain specimens from old and generally closed localities, in addition to some interesting contemporary things many of which did not reach the general market. Sprayed with a very light enamel to prevent crumbling.
