Desert rose (crystal) A desert rose is an intricate rose -like formation of crystal clusters of gypsum or baryte, which include abundant sand grains. [ 1] The "petals" are crystals flattened on the c axis, fanning open in radiating clusters. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, [ 1] such as ...
Claystone – Clastic sedimentary rock composed primarily of clay-sized particles. Coal – Combustible sedimentary rock composed primarily of carbon. Conglomerate – Sedimentary rock composed of smaller rock fragments. Coquina – Sedimentary rock that is composed mostly of fragments of shells.
Lot's wife. In the Bible, Lot's wife is a figure first mentioned in Genesis 19. The Book of Genesis describes how she became a pillar of salt after she looked back at Sodom (the "looking taboo" motif in mythology and folklore). She is not named in the Bible, but is called Ado or Edith in some Jewish traditions.
Salt. Rock salt (halite) In common usage, salt is a mineral composed primarily of sodium chloride (NaCl). When used in food, especially in granulated form, it is more formally called table salt. In the form of a natural crystalline mineral, salt is also known as rock salt or halite. Salt is essential for life in general, and saltiness is one of ...
Salt domes are vertical diapirs or pipe-like masses of salt that have been essentially "squeezed up" from underlying salt beds by mobilization due to the weight of the overlying rock. Salt domes contain anhydrite , gypsum , and native sulfur , in addition to halite and sylvite .
Avery Island (historically French: Île Petite Anse) is a salt dome best known as the source of Tabasco sauce. Located in Iberia Parish, Louisiana, United States, it is about three miles (4.8 km) inland from Vermilion Bay, which opens onto the Gulf of Mexico. A small human population lives on the island.
Himalayan salt, which is composed of large grains of rock salt mined in Pakistan, is touted as a healthier version because it contains traces of potassium, silicon, phosphorus, vanadium, and iron. The amounts are enough to color the crystals, giving them a more "natural" appearance, but are nutritionally irrelevant.
The white rocks at left center are the gypsum and anhydrite carapace of the diapir. A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at ...
