Difference Between Gypsum and Anhydrite | Difference …

 · It is sometimes used as an ornamental stone or as a soil conditioner. It has industrial uses too for instance as a drying agent or as a cement additive. Salt domes give the best anhydrite crystals because the domes absorb any underground water thereby preventing it from entering the structure of the Anhydrite, as water would cause it to alter to gypsum.


The "soil" of the coastal dune is saline, alkaline, and sodic, with a thin compacted gypsum (sodic-petrocalcic) layer just under the topsoil. Agricultural production in the region is very limited, due in part to the poor soil conditions (the gypsum layer effectively prevents roots from penetrating into the more humid layer underneath) and in part to the lack of rainfall.
