ANHYDRITE

Billingham Anhydrite Mine, Stockton-on Tees, County Durham

Anhydrite is an evaporite mineral that occurs in extensive deposits formed by the evaporation of large volumes of sea water. It consists of calcium sulphate (CaSO4).

  

Anhydrite occurs with gypsum which is also calcium sulphate, the difference being that gypsum (CaSO4·2H2O) contains water molecules in the crystal structure.

  

Billingham anhydrite mine was located on the north bank of the River Tees, and operated by ICI. In the 1950s the mine had 200 miles of underground roadways. The mine closed in 1978.
