Gypsum deposits in a shallow marine condition with a mostly arid type climate.Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water. This study investigates the depositional setting and diagenetic processes of gypsiferous sediments known as the Koluz gypsum member located in the northeast of Van (Eastern Anatolia-Turkey).

Sedimentary rocks are formed by 5 processes, there are erosion, weathering, transport, deposition, and diagenesis process (Boggs, 1991). These 5 processes with 4 types of rocks make up a cycle that is known as sedimentary cycle. The properties of sedimentary rocks such as sediment textures and structures, are formed ...
9.4 Depositional Environments and Sedimentary Basins. The setting in which sediments are accumulated is called a depositional environment. (Some of the more important of these environments are illustrated in Figure 9.19.) Thus far you’ve seen that some types of sedimentary rocks—coal, and gypsum, for example—require very specific ...
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.Selley (1978) [4] considered the shapes of well-log curves as basic tool to interpret depositional facies because shape of log is directly related to the grain size of rock successions.

Depositional Environments A sedimentary environment is a geographic location characterized by a particular combination of geologic processes and environmental conditions. Geologic processes include the currents that transport and deposit sediments (water, wind, or ice) and the plate tectonic settings that affect sedimentation. the depositional environment. Sediment deposited rapidly in areas of little current or wave action is usually poorly-sorted, because there is little chance for the removal of fine-sized grains. There is more opportunity for size sorting when sediment slowly accumulates in a high-energy environment.Depositional Environments A sedimentary environment is a geographic location characterized by a particular combination of geologic processes and environmental conditions.
