Where do you find anhydrite?

Anhydrite is commonly found in sedimentary rock formations, particularly in evaporite deposits where it crystallizes from the evaporation of saline water. It often occurs in association with gypsum, halite, and other evaporitic minerals. Major deposits can be located in regions such as Michigan, Texas, and parts of Europe, particularly in areas with historical oceanic basins. Anhydrite can also be found in some hydrothermal veins and as a secondary mineral in limestone.
