| 9 | Gypsum is the most common sulfate mineral and differs from [[anhydrite>>doc:Environmental Surveys.Rock types.Salts.Anhydrite.WebHome]] in its water content. Gypsum has two water molecules attached to its sulfate molecules giving the following chemical name: CaSO,,4,,*2H,,2,,O. The mineral can be found in deposits together with halite, anhydrite, sulfur, calcite and dolomite. | ||
