Formation & Environments. Sedimentary gypsum forms under high evaporative conditions in sedimentary rocks, both clastic and carbonate. It usually requires desert conditions in shallow marine basins ...As a rock, gypsum is a sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Because it is deposited in this environment ...The lower Gypsum Spring unit was deposited in a restricted basin, with the middle and upper units reflecting subsequent deepening and freshening of the Jurassic sea. Most of the Sundance Formation was deposited in a relatively quiet, open-marine environment. Individual units represent shoaling conditions during minor regressions.ERDOĞAN TEKİN. DOI. - Abstract.

Textural observations, and compositional analyses of veins are important for understanding the vein formation processes. Veins filled with gypsum often consist of a median zone with fiber zones on both sides of it (Fig. 2 f), which is a distinctive feature of antitaxial fibrous veins (Bons et al., 2012).Antitaxial gypsum veins have been …practical importance. For example, knowing the depositional environment of sedimentary rocks containing petroleum and natural gas is critical for siting exploration and exploitational wells. • Sedimentary textural characteristics like rounding and sorting are clues to depositional environments. For example, desert sand duneThe post-depositional gypsum veins are observed to cut fine siliciclastics and mud rocks. This indicates the remobilisation of gypsum upon shallow burial. ...

A depositional environment is a particular location on the earth surface (e.g., river channel, tidal inlet, submarine fan, reef) where a limited range of physical, chemical, and biological processes take place, resulting in the generation of a limited range of sedimentary deposits. Igneous rocks are sometimes considered primary rocks because they crystallize from a liquid. In that case, sedimentary rocks are derived rocks because they are formed from fragments of pre-existing rocks. Formation of Sedimentary Rocks.
