melanterite
Melanterite is a mineral form of hydrous iron(II) sulfate: FeSO4·7H2O. It is the iron analogue of the copper sulfate chalcanthite. It alters to siderotil by loss of water. It is a secondary sulfate mineral which forms from the oxidation of primary sulfide minerals such as pyrite and marcasite in the near-surface environment. It often occurs as a ''post mine'' encrustation on old underground mine surfaces. It also occurs in coal and lignite seams exposed to humid air〔 and as a rare sublimate phase around volcanic fumaroles.〔 Associated minerals include pisanite, chalcanthite, epsomite, pickeringite, halotrichite and other sulfate minerals.〔 It was first described in 1850.〔 ==Gallery==
