Geology. A curious white line on the horizon, White Sands has long sparked wonder in people passing through the Tularosa Basin. Standing on top of a dune overlooking this sea of sand, it can be difficult to imagine where all the brilliant white sand came from. To understand the origins of the world’s largest gypsum dunefield, we must look ...Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.Diverse microscopic fossils are abundant in primary sedimentary gypsum of the Late Miocene (Messinian) Vena del Gesso Formation at the Monte Tondo Quarry in northeastern Italy (Figs. 1A, 2, 3 ...Quick Answer.
