Depositional environments or facies can be recognized in terms of lithology, depositional structure, geometry, fossil content (including micro-fossils and fossil fragments) and paleocurrent trends. Channel environments have an erosional surface which is typically overlain by mainly pebbles or conglomerates.

The sandstone of the Lokoja and Patti Formations constitutes the main reservoirs of the southern Bida Basin, Nigeria.

Transitional.People use safe deposit boxes to hold a variety of important papers and other items. Because the uses are so varied they come in a variety of different sizes. Most financial institutions offer them for rent or as a perk to their customers.Within the concept of the use of sedimentary structures for environmental interpretation, we are including such features as primary sedimentary structures, trace fossils, and other characteristics of the early depositional and early diagenetic environment, three-dimensional facies patterns, and the geometry of large-scale sand bodies.

Depositional Environment. The Tapeats Sandstone consists of a mixture shallow marine, intertidal, and coastal plain deposits associated with an eastward advancing shoreline. The upper transitional beds represent sediment deposited on a deepening shallow-marine shelf. Jun 10, 2021 · The wave and current-rippled sandstone facies (FA4a), flaser-bedded heterolithics (FA4b), and bioturbated muddy heterolithics (FA4c) indicate deposition in a tidal-flat environment. The sandstone with plant debris facies (FA5a) and carbonaceous mudstone and coal seams (FA5b) indicate a coastal plain/swamp environment.

A fluvial depositional environment is one in which sedimentary rocks are deposited by moving water. The water may be flowing in a river, moving in a lake, or an ocean. The sediments that are deposited in this environment are typically transported by the water and are deposited as the water flow slows down or stops.aqueous conditions. Thus, the environment of deposition of the Navajo Sandstone is still in question. In recent years, a vast amount of new information on modern eolian environments has been published. Because of this new informa­ tion, a comparison between the Navajo Sandstone and modern eolian environments is needed.A 2019 radioisotopic analysis suggests that the Navajo Sandstone formation is entirely Jurassic, extending for about 5.5 million years from the Hettangian age to the Sinemurian age.
