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.

It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum.

Back to Rocks and Minerals Articles Kelly Snyder and Peter Russell Gypsum, hydrated calcium sulphate, Ca SO4.2H2O, is a common mineral formed mainly by the evaporation of sea water.
