Gypsum depositional environment
Allen Pyle. Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.The depositional environment, diagenetic and depositional settings of gypsum deposits from Bi'r El Ghanem, NW Libya.

Figure 5.3.1 5.3. 1: Enlarged image of frosted and rounded windblown sand grains. Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted. Sediment grains in sandstone can having a wide variety of mineral compositions, roundness, and sorting.Gypsum. Gypsum is a mineral commonly found in Kansas. When salty seawater evaporates, dissolved salts, including the mineral gypsum, are left behind. If conditions are right, large quantities of gypsum build up into thick beds of sedimentary rock. The gypsum throughout the state was deposited during the Permian, when an arm of the inland sea ...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, …Which Sedimentary Rocks are found in which environments?

It is in association with gypsum that both the miner-als transform into one another by the addition and removal of water.

While older studies traditionally used the presence of halite and gypsum to argue for marine or marginal marine depositional origin (Dane Picard, Lee, & High, 1968; Maughan, 1966), sedimentological and geochemical data obtained from Permian redbeds and evaporites of the mid-continent of North America ...This means that radioactive source is associated in varying composition and depends upon the depositional environment. That is the main reason that the normal GR trends are used to interpret the subsurface sedimentary facies in the absence of 3D seismic data and well core data. 3.

Massive dark to yellowish gypsum: The massive dark to yellowish gypsum displays a competent lithology which can be distorted by gypsum porphyroblasts or, more commonly, by white gypsum nodules (Fig. 10 H). It is as well frequently affected by satin-spar gypsum veins. Shallow-water evaporites, almost exclusively gypsum, anhydrite, and halite, typically interfinger with tidal flat limestone and dolomite and fine-grained mudrock. Deep-basin environment.

One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.1. Freeze-thaw- occurs when water continually seeps into cracks then freezes and expands which eventually breaks the rock apart. 2. Exfoliation- occurs as cracks develop parallel to the land surface, a consequence of reduction in pressure due to uplift and erosion. Chemical: 1.The Kohat Basin is situated in the Himalayan foothills.
