Such a temperature can be produced in nature only by extremely deep burial or by intrusion of igneous rock. They proposed that temperature was more effective than pressure in the inversion of gypsum. McCormak (1926) likewise concluded that temperature was a more important factor than pressure in the dehydration of gypsum.
Igneous rocks Andesite · ... Gypsum as a rock type is an aggregate of gypsum crystals. Gypsum is an evaporite and is usually associated with other evaporite minerals like halite and anhydrite. Gypsum occurs in different forms: massive alabaster, fibrous satin spar, selenite crystals. Gypsum is an important industrial mineral.
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Clastic: basic sedimentary rock which is composed of clasts: little pieces of broken-up rock which are joined together as a result of compaction and cementation. Chemical: these are often formed as a result of repeated flooding and evaporation. When water evaporates it leaves a layer of dissolved minerals behind. Deposits of salt and gypsum are characteristic examples of these processes.
