    Gypsum, common sulfate mineral of superb industrial significance, composed of hydrated calcium sulfate (CaSO4 ·2H2O) In properlydeveloped crystals the mineral normally has been called selenite The fibrous large variety has a silky lustre and is known as satin spar; it is translucent and opalescent and is valued for ornaments and jewellery The finegrained big variety called alabaster is

  • Carbonates, Evaporites, and Accessory Minerals

    Gypsum is the most common evaporite mineral occurring in soils Its occurrence and behavior is similar to that of calcite, but it is significantly more soluble; hence, it is generally found in more arid environments than calcite It can be inherited from gypsiverous parent materials or formed as a secondary mineral It can occur as fibrous masses, small dispersed crystals, concretions, or in

  • Caring For Mineral Specimens | McDougall Minerals

    One common example is gypsum (also referred to as selenite) – it won’t dissolve, but the lustre will dull over time Another example is pyrite in matrxi from Navajun, Spain – the pyrites don’t mind water but the matrix will fall apart, dropping the crystals out Be very careful with water and mineral specimens – always read mineral literature and online before you subject your
