Gypsum is another common mineral formed in carbonate caves by cave making processes, though it is uncommon in Missouri caves.Fine-grained white or lightly tinted forms of gypsum known as alabaster have been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Etymology and history The word gypsum is derived from the Greek word γύψος ( gypsos ), "plaster". [9]In addition to its standard rock form, gypsum also develops into unique crystal varieties and habits that are highly valued: Selenite. Selenite is the clear, transparent crystalline form of gypsum that shows glassy luster and has perfect cleavage. It commonly occurs as thin flattened crystals, but can also form "fishtail" and equant shapes.Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.
