The Feos laminated gypsum was interpreted as continental deposits based on depositional facies and brackish and freshwater fossils from marl/sandstone turbidites (Van de Poel, 1994). The Feos gypsum conglomerate and gypsum sandstone was probably derived from the physical redeposition of the Yesares selenites.Gypsum is a soft, light-colored sedimentary rock deposited in ancient seas that covered Ohio during the Silurian Period. It occurs in both mineral form (selenite) and as a rock in bedded layers. Gypsum occurs interbedded with salt (halite, NaCl) and anhydrite (CaSO 4 ).

Table 6.4 provides a summary of the processes and sediment types that pertain to the various depositional environments illustrated in Figure 6.3.1.The nodular lithofacies with wavy, irregular laminated lithofacies may show deposition in supratidal, sabkha environment and the massive gypsum lithofacies, associated with more even, laminated lithofacies may indicate precipitation in subaqueous, intertidal to subtidal environment (e.g., Schreiber et al., 1976).The emphasis of this study was to use diagenetic criteria to identify the environment of deposition of gypsum and focused on field investigations and studying the petrography …Aug 20, 2009 · Overheads shown in Lab. SEDIMENTARY ROCK: Made from sediments consolidated at the earth's surface. The sediments are deposited at the earth's surface by water, wind, glacial ice, or bio-chemical processes. Typically the sediments are deposited in layers under COOL conditions [thereby distinguishing it from a layered volcanic rock (TUFF)]. Shallow-water evaporites, almost exclusively gypsum, anhydrite, and halite, typically interfinger with tidal flat limestone and dolomite and fine-grained mudrock. Deep-basin environment. Most of the thick, laterally extensive evaporite deposits appear to have been produced in deep, isolated basins that developed during episodes of global aridity.Oct 27, 2020 · The sedimentary environments of carbonates can be divided roughly into platform, marginal platform and deep basin while the platform is the main depositional environment for evaporites. Our research area-the Tarim Basin in Cambrian is exactly the typical case which features the thick and extensive carbonates and salts. Jun 29, 2020 · 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).

The depositional environment and sediments being deposited will define the grain size, its sorting, and its …What does grain size indicate about a specimen’s environment and the energy of transport? Grain size is related to the energy of the depositional environments. The energy of transport can be by wind, water, glaciers, and gravity. For example, if the grains are the same size, the sediment was sorted during a long transportation.Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2 ). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges. Early people took advantage of how chert breaks and used it to fashion ...Gypsum is a relatively common mineral in a number of environments. It is found in sedimentary rocks, either as a primary precipitate from sea or saline lake waters or as a alteration of minerals such as anhydrite. It is deposited from groundwater with sedimentary rocks such as shale or limestone. Gypsum also forms from low temperature hydrothermal fluids. It can form during the weathering of ...
