About the book
Evaporites are a water-soluble mineral sediment that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes.
The chemistry of modern and ancient evaporites, and their parent waters, is reflected in the mineralogy and facies distribution remaining in the geologic record.
Evaporites are important economically because of their mineralogy, their physical properties in-situ, and their behavior within the subsurface. Evaporites as seals or cap rocks control the reservoir geometry and producibility. Economically important evaporite minerals are common in nature, such as; Sylvite, also known as Potash, or potassium chloride. It is used as a fertilizer ingredient and is an important plant nutrient. Gypsum (calcium sulfate) is also an important evaporite mineral and is primarily used to make building materials such as drywall. Halite (sodium chloride) is what one normally thinks of as “salt” and has been an important commodity for millennia.
