text: Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.
text: These features, therefore, do not reveal whether the gypsum was deposited as such or subsequently altered from anhydrite.
text: As already discussed, either gypsum or anhydrite may be deposited from an evaporating body of sea water, depending upon the salinity and temperature.
text: Fresh water added to a basin where gypsum was being deposited should dissolve previously precipitated gypsum until saturation with respect to calcium sulfate is again reached.
text: Although surface evidence is lacking, subsurface evidence indicates that the anhydrite-gypsum zone of the Wellington formation is stratigraphically directly below the salt, that is, gypsum and salt were deposited successively, not contemporaneously.
