As a consequence, gypsum typically occurs as layers associated with limestone, dolostone, shale, and rock salt. As seawater evaporates, gypsum is the first ‘salt’ to be precipitated, followed by anhydrite, halite, and finally sylvite.

Feldspar (sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. [3] The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars.
