Gypsum depositional environment
A depositional environment is a natural or artificial layer of sedimentary material that covers an area and is created by the deposition of material from the atmosphere, water, or land. Depositional environments can be found in various places around the world. Some examples of depositional environments are beach sands, river …Gypsum is a chemical sedimentary rock.

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.Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. ….

Bedding can form in almost any depositional environment. Figure 6.19 The Triassic Sulphur Mt. Formation near Exshaw, Alberta. Bedding is defined by differences in colour and texture, and also by partings (gaps) between beds that may otherwise appear to be similar.Gypsum will form in any environment in which there is high evaporation of marine waters, and an absence of abandant clastic sediment to maske it. Formation & Environments. …Depositional environment. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.
