At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 6000 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.\n\u003Cp>The sulfate minerals all have one or more sulfate anions (SO4 -2).\n\u003C\u002Fp>\u003Cp>Hexahydrite is a hydrous magnesium sulfate mineral, MgSO4·6H2O.  It has a nonmetallic luster, is usually clearish to whitish, has a white streak, and is fairly soft.  It usually occurs as earthy, powdery efflorescence on some rock surfaces.\n\u003C\u002Fp>\u003Cp>The sample seen here is hexahydrite powder formed as water leached out material from sedimentary rocks of the Eocene-aged Green River Formation.
