    Halite salt: The mineral Halite information and pictures

    Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.

    How Is Gypsum Formed? | Hunker

    In the case of "desert roses" gypsum crystals found around the world in arid sites, formation occurs with evaporation as the level of the water table changes. Gypsum can also be formed diagenetically by oxidation. This chemical reaction occurs when oxidation of existing sediments causes gypsum to form and replace other minerals in the sediments.

    Evaporite (/ ɪ ˈ v æ p ə r aɪ t /) is the term for 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.
