Gypsum depositional environment
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 …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.

Breccia forms where broken, angular fragments of rock or mineral debris accumulate. 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.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. Cant (1992) [5] defined five different log curve shapes used to interpret the depositional environment and also considered the study of core with relation to logs as …Underground mapping at mines 2 and 3 reveals that a wide range of facies and textures are present in the mined gypsum bed and that the enclosing sediments were deposited in a …The depositional environment of the outcrop is interpreted as shallow marine shelves interchanging with intertidal flats and supratidal ...

Models for evaporate, selenite and gypsum microbialite deposition in ancient saline basins.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, CaSO 4 ·2H 2 O, may be associated with calcite and dolomite in some sequences of sedimentary rock. If present, this highly soluble sulfate mineral can have a big impact on the chemical composition of cave waters ... Thus grain type is one of the keys to interpreting their depositional environment. Limestones form, almost without ...

Bedding - sediments are arranged into layers defined by bedding planes; usually horizontal, but may also be subhorizontal or curved.. Graded bedding - bedding in which the particles are sorted according to density, …In attempting to recreate the depositional environment of a sedimentary sequence, one typically evaluates the authigenic minerals preserved in the geologic record and infers the composition of fluid and temperature under which the minerals could have formed. ...

Our research area-the Tarim Basin in Cambrian is exactly the typical case which features the thick and extensive carbonates and salts.
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.Browse over 1 million classes created by top students, professors, publishers, and experts.
