gypsum and halite are formed by what process

  • Gypsum Minerals Education Coalition

    Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock typically found in thick beds or layers.

    Halite the natural form of salt is a very common and well-known mineral. It is found in solid masses and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions and may also be below sea level without an outlet. These lakes evaporate during dry seasons causing a recession in the water level and an increase of salinity content.
