Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. Evaporite deposits occur in both marine and nonmarine sedimentary successions.Gypsum is a mineral composed of calcium sulfate dihydrate (CaSO 4 ·2H 2 O), so anoxic environments would be less favourable for gypsum precipitation and preservation than oxic environments (e.g. Sloss, 1969). Gypsum precipitation may thus have been restricted to relatively shallow levels in the Mediterranean basin, if the Mediterranean water ...Depositional environments.

If this hypothesis is correct, then another possible implication can be inferred. The definition of the depositional environment of gypsum based on the geochemistry (δ 18 O and δD) of the crystallization water could also be affected.

"High-Energy" and "Low-Energy" Depositional Environments. Flowing water is the dominant natural force causing erosion and deposition on Earth. The faster the water moves, the higher the energy in a physical setting. As flowing water increases in speed, the more it may become turbulent, increasing its ability to lift and move particles.

The depositional environment recorded by bedded anhydrite, then, must be that of its bedded gypsum precursor. The criteria used to interpret the depositional setting of bedded gypsum, whether ephemeral, shallow perennial or deep perennial, should be applied to the bedded anhydrite.
