Environment of Deposition.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. The preserved characteristics of each such deposit define its facies.For example, in the Grand Canyon, rock strata of the same geologic age include many different depositional environments: beach sand, tidal flat silt, offshore mud, and farther …A depositional environment, also known as a sedimentary environment, is a physiography setting where sediments are deposited. A depositional setting can be a river, a lake, a delta, a lagoon and the vast ocean.Packstones indicate a range of depositional properties. Mud suggests lower-energy processes, whereas the abundance of grains suggests higher-energy processes. Dunham (1962) provided several scenarios for the origin of packstones: (1) they may be a product of compacted wackestones, (2) they may result from early or late mud infiltration of ...Mar 14, 2015 · Limestone is a sedimentary rock that is primarily composed of Calcium carbonate in the form of calcite mineral.

They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor. The limestone deposited in the far shelf comes from CaCO 3 dissolved in the river waters during the weathering of feldspars. Limestones (carbonates) typically do not form in the presence of clastics, such as sandstone and shale, and so are not deposited until the far shelf environment, beyond the reaches of shale deposition.
