It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate).

Gypsum is a mineral made up of hydrated calcium sulphate that forms in certain types of sedimentary rock. When first mined, the gypsum mineral is in crystal form–its primary form. The gypsum crystal is clear and can be easily mistaken for a clear quartz crystal.3. Compacted Clay. Another instance when I have found rock dust helpful is when improving compacted clay soil. Clay is loaded with minerals. However, until you can add enough organic matter and have enough soil life to begin to infiltrate those tightly-knit clay particles, those minerals are inaccessible by plants.Sedimentary rocks are the second great rock class. Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water. They usually consist of layers or strata; hence they are also called stratified rocks.
