Sedimentary rock - Wikipedia
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (150 megapascals (1,500 bar)) [clarify], causing profound physical or chemical change.The protolith may be a sedimentary, igneous, or existing metamorphic rock.

This is a common way for chemical sedimentary rocks to form and the rocks are commonly called evaporites. They are typically made up of the minerals halite (calcium chloride, or rock salt) and gypsum (calcium sulfate). Another way to precipitate minerals out of water is to change the temperature (or the acidity) of the water rather than evaporate the water. This is how rocks …
