Original: Jul 3, 2016. Gypsum is a naturally occurring stone, a metallic salt of calcium. It commonly forms as an evaporite from the dissolution of limestone by exposure to sulphuric acid from volcanic activity. Under certain conditions, continual cycles of dissolution and evaporation will agglomerate into a “primary” deposit of gypsum.To illustrate the depositional environment of the Aşkale Formation, tectonic evolution of the Eastern Anatolia should be well explained. ...

Allen Pyle. Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2 ).
