A sedimentary rock that consists of one or more minerals formed as precipitates from the evaporation of a saline solution, such as saltwater. Usually, the first evaporite to form from saltwater is calcium, followed by gypsum and then halite.
Also asked, how is an evaporite formed?
Evaporites. Rocks formed by the evaporation of water are called evaporites - gypsum, anhydrite, halite (common salt). This evaporation may occur in either shallow basins on land or in the sea. When seawater evaporates, the salts precipitate and settle to the bottom.
What is an example of an evaporite sedimentary rock?
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. Evaporites are considered sedimentary rocks and are formed by chemical sediments.
How does a chemical rock form?
Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water.
