Where is shale deposited.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock. Common Sedimentary …Modified date: 23/04/2023. Chert. Chert is a fine-grained sedimentary rock composed of quartz (SiO2) that is microcrystalline or cryptocrystalline quartz. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits.Shale rock is formed from clay minerals and quartz minerals being deposited in certain depositional environments. These environments include slow-moving aquatic environments such as lakes, ponds ...The Burgess Shale is a fossil -bearing deposit exposed in the Canadian Rockies of British Columbia, Canada.

The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season. As a result, shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in river deltas, on floodplains and offshore below the wave base. Thick deposits of shale are found near ancient continental margins and foreland basins.Apr 5, 2022 · The oil shale is mainly deposited at the end of the muddy water area and clear water area far away from coarse clastic minerals and is enriched in low-lying parts of palaeotopography, such as deep depressions, local sub-depressions on the basin slope, and low-energy parts before and after local prominence or slope break belt. It turned out that in 2014-2016, the company, evading taxes in the amount of about one billion hryvnias, converted profits into fictitious expenses through shell companies. By decision of the Ukrainian court, Burisma was banned from the sale of produced gas and seized 46 wells in five regions.
