Organic Sedimentary Rocks - CliffsNotes

Organic sedimentary rocks form from the accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Rocks that were once swampy sediments or peat beds contain carbon and are black, soft, and fossiliferous. Rich enough in carbon to burn, coal is an organic sedimentary rock that is a widespread and important fuel source.Organic-rich sedimentary rocks - Wikipedia,Organic-rich sedimentary rocks are a specific type of sedimentary rock that contains significant amounts (>3%) of organic carbon. The most common types include coal, lignite, oil shale, or black shale. The organic material may be disseminated throughout the rock giving it a uniform dark color, and/or it may be present as discrete occurrences of tar, bitumen, asphalt, petroleum, coal or carbonaceous material. Organic-rich sedimentary rocks may act as source rockswhich generate hydrocarbons that accumulate in other sedi…Sedimentary rock - Organic-rich sedimentary deposits,,Sedimentary rock - Sedimentary rock - Organic-rich sedimentary deposits: Coal, oil shale, and petroleum are not sedimentary rocks per se; they represent accumulations of undecayed organic tissue that can either make up the bulk of the material (e.g., coal), or be disseminated in the pores within mudrocks, sandstones, and carbonates (e.g., oil shale and petroleum).

Sedimentary Rocks | National Geographic Society

Oct 22, 2019· Organic detrital rocks form when parts of plants and animals decay in the ground, leaving behind biological material that is compressed and becomes rock. Coal is a sedimentary rock formed over millions of years from compressed plants. Inorganic detrital rocks, on the other hand, are formed from broken up pieces of other rocks, not from living,Sedimentary rock - Wikipedia,Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological,Sedimentary Rocks - Arizona State University,Chemical sedimentary rocks are formed by precipitation of different elements dissolved in water. For example, halite (rock salt) forms when water evaporates away and leaves the dissolved salt behind. There are also organic sedimentary rocks, which are made up of plant material. Coal is considered an organic sedimentary rock.
