In addition, the primary fluid inclusions along the growth bands in chevron and cumulate halite show that it was a shallow water environment of halite deposition. Third, gypsum would have been precipitated from varying degrees of dilution during the early crystallization of rock salt and halite recrystallization and would have occurred ...Depositional environment. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.

It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name “gypsum” is derived from the Greek word “gypsos,” which means “plaster” or “chalk.”.

Oct 27, 2020 · The sedimentary environments of carbonates can be divided roughly into platform, marginal platform and deep basin while the platform is the main depositional environment for evaporites. Our research area-the Tarim Basin in Cambrian is exactly the typical case which features the thick and extensive carbonates and salts. To illustrate the depositional environment of the Aşkale Formation, tectonic evolution of the Eastern Anatolia should be well explained. ... In the present day, conversion of syn-sedimentary anhydrite nodules into gypsum in a sabkha environment is still an ongoing process in the Gulf of Basra (e.g. Butler, 1969, Aref et al., 1997).Gypsum is a common primary and secondary mineral of arid and semi-arid region soils. Gypsum is by far the dominant sulfate mineral in soils. A saturated gypsum solution at 25C contains ~15 mM CaSO 4, or 2.63 g/L.
