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.Gypsum speleothems form because water seeping into the cave often contains small amounts of gypsum (calcium sulfate, CaSO4) picked up from the limestone or overlying sandstone. When this water evaporates in the cave, it deposits gypsum in the form of needles, beards, flowers, or spiders. Gypsum formations are found only in dry parts of the cave.
