ANHYDRITE


Anhydrite is an evaporative sedimentary rock, formed when a very salty brine containing a large percentage of calcium sulfate evaporates in hot conditions. These conditions allow the precipitation of the mineral anhydrite instead of the hydrated mineral gypsum.

Anhydrite beds can be quite large, and generally contain other evaporite minerals such as gypsum and halite.
