Gypsum depositional environment.

modern depositional environments, and laboratory studies in tanks and channels. So cross stratification is probably the single most useful tool in interpreting the physical aspects of loose-sediment depositional environments. That's why I'm devoting what probably will seem to you to be inordinate space in these notes. 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.Conglomerate characteristics/what it's made from. - gravel. - coarsely grained. - poorly sorted.

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. 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. This is because the crack-and-seal mechanism may introduce new variable aliquots of water due to the syntaxial ...Subaqueous deposits of aragonite, gypsum, and halite are accumulating in shallow solar salt ponds constructed in the Pekelmeer, a sea-level sauna on Bonaire, Netherlands Antilles. Several halite facies are deposited in the crystallizer ponds in response to differences in water depth and wave energy.The layers in this sandstone rock are one of the many depositional features preserved in sedimentary rocks.
