The most common minerals that are generally considered to be the most representative of marine evaporites are calcite, gypsum and anhydrite, halite, sylvite, carnallite, langbeinite, polyhalite, and kainite. At this point, the mineral gypsum begins to form, which is then followed by halite at 10%, excluding carbonate minerals that tend not to be evaporites.
It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates.

At this point, the mineral gypsum begins to form, which is then followed by halite at 10%, excluding carbonate minerals that tend not to be evaporites.
It also forms as an evaporite mineral and as a hydration product of anhydrite.

Kainite ( or ) (KMg(SO 4 )Cl·3H 2 O) is an evaporite mineral in the class of "Sulfates (selenates, etc.) with additional anions, with H 2 O" according to the Nickel-Strunz classification.

Sedimentary rock

Evaporite is the term for a water-soluble mineral sediment that results from concentration and crystallization by evaporation from an aqueous solution.
Common chemical sedimentary rocks include oolitic limestone and rocks composed of evaporite minerals, such as halite (rock salt), sylvite, baryte and gypsum.

Trona

Trona ore
Common minerals that are found in these deposits include blödite, borax, epsomite, gaylussite, glauberite, mirabilite, thenardite and trona.
Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 •NaHCO 3 •2H 2 O) is a non-marine evaporite mineral.

Kieserite

Kieserite (MgSO 4 ) may also be included, which often will make up less than four percent of the overall content.
Kieserite commonly occurs in marine evaporites and rarely in volcanic environments as a sublimate.

Thenardite

Thénarditethenardite mineral
Common minerals that are found in these deposits include blödite, borax, epsomite, gaylussite, glauberite, mirabilite, thenardite and trona.
Thenardite is an anhydrous sodium sulfate mineral, Na 2 SO 4 which occurs in arid evaporite environments.

Gaylussite

Common minerals that are found in these deposits include blödite, borax, epsomite, gaylussite, glauberite, mirabilite, thenardite and trona.
It is formed as an evaporite from alkali lacustrine waters.

Messinian salinity crisis

The most significant known evaporite depositions happened during the Messinian salinity crisis in the basin of the Mediterranean.
Sediment samples from below the deep seafloor of the Mediterranean Sea, which include evaporite minerals, soils, and fossil plants, show that the precursor of the Strait of Gibraltar closed tight about 5.96 million years ago, sealing the Mediterranean off from the Atlantic.

Sylvite

The most common minerals that are generally considered to be the most representative of marine evaporites are calcite, gypsum and anhydrite, halite, sylvite, carnallite, langbeinite, polyhalite, and kainite.

Epsomite forms as encrustations or efflorescences on limestone cavern walls and mine timbers and walls, rarely as volcanic fumarole deposits, and as rare beds in evaporite layers such as those found in certain bodies of salt water.

Dead Sea

Examples of modern non-marine depositional environments include the Great Salt Lake in Utah and the Dead Sea, which lies between Jordan and Israel.
The Sedom Lagoon deposited evaporites mainly consisting of rock salt, which eventually reached a thickness of 2.3 km on the old basin floor in the area of today's Mount Sedom.

Sabkha

A term typically used by Earth scientists, a sabkha is a coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate.

Mineral

Evaporite is the term for a water-soluble mineral sediment that results from concentration and crystallization by evaporation from an aqueous solution.
Halite and sylvite commonly form as evaporites, and can be dominant minerals in chemical sedimentary rocks.

Blödite

Caspian Sea

CaspianCaspian regionCaspian Sea basin
During warm and dry climatic periods, the landlocked sea almost dried up, depositing evaporitic sediments like halite that were covered by wind-blown deposits and were sealed off as an evaporite sink when cool, wet climates refilled the basin.

Rift

Effective regional seals may be present within the post-rift sequence if mudstones or evaporites are deposited.

Mediterranean Sea

The most significant known evaporite depositions happened during the Messinian salinity crisis in the basin of the Mediterranean.
Because it is a near-landlocked body of water in a normally dry climate, the Mediterranean is subject to intensive evaporation and the precipitation of evaporites.
