Gypsum happens in considerable beds affiliated with other evaporite minerals (e.g., anhydrite and halite), notably in Permian and Triassic sedimentary formations; it really is deposited from ocean brine, accompanied by anhydrite and halite. Furthermore, it takes place in sizeable amount in saline lakes and salt pans and is an important constituent of cap rock, an anhydrite-gypsum rock forming a masking on salt domes, as in Texas and Louisiana.
