Pretty normally it really is shaped in the hydration of anhydrite by floor waters and groundwaters, and, Therefore, many gypsum gypsiferous strata grade gypsum downward into anhydrite rocks. This substitution brings about a thirty per cent to fifty p.c quantity raise and leads to intense, restricted folding in the remaining anhydrite levels. Gypsum also takes place disseminated in limestones, dolomitic limestones, and several shales.
