Mar 01, 2019· Answered by Kurt Edwards, Geologist and GIS Analyst, INL ESER Program he short answer is yes, coal is a sedimentary rock Coal is formed mainly from plant material that accumulates in a swampy environment These plants that become coal, lived before and during the time of the dinosaurs When the plants died they would sink,
Shale is an argillaceous rock, and argillaceous rocks are "detrital sedimentary rocks"  They are composed of clays and the bedding plane within the shales is "due to the orientation of the clay minerals"  Clearly a sedimentary rock Coal however, as you state in your question is derived from organic material - vegetation
First, lignites, the lowest coal rank, often contain recognizable plant remains Second, sedimentary rock layers above, below, and adjacent to coal seams contain plant fossils in the form of impressions and carbonized films (eg, leaves and stems) and casts of larger parts such as roots, branches, and trunks
May 14, 2018· Sedimentary rocks form from the weathering of other rocks, dead organic remains or chemical precipitation Processes used to form sedimentary rocks include classic sedimentation, chemical sedimentation and biochemical sedimentation Examples of sedimentary rocks include shale, limestone and coal
Dec 26, 2017· Of the three categories of rocks, sedimentary, igneous and metamorphic, sedimentary is the closest type that coal could fit into Coal was not derived from molten material, so is not igneous by definition It was not transformed under temperature .
Feb 23, 2018· Sedimentary rocks can sometimes be high in the coal content This happens mainly when there are deposits of plant materials Over time, the plant matter is altered greatly to form the coal we use Some sedimentary rocks may even be entirely made up of coal!
Coal is a sedimentary rock of biochemical origin It forms from accumulations of organic matter, likely along the edges of shallow seas and lakes or rivers Flat swampy areas that are episodically flooded are the best candidates for coal formation During non-flooding periods of time, thick accumulations of dead plant material pile up

The following is a list of rock types recognized by geologistsThere is no agreed number of specific types of rocks Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type
Coal is an organic sedimentary rock which is the prehistoric vegetation that are deposited at swamps, subjected to heat and pressure over million of years This is composed mainly of carbon, hydrogen and oxygen Coal along with oil and gas is fossil fuel, can also be called combustible rock Coal is a flammable black hard rock used as a solid fossil fuel
Sedimentary Rocks Let’s learn some facts about Sedimentary rocks! At the end of the article, review our quiz sheet in the activity section to test what you have learned To geologists, people who study rocks, soil, fossils, mountains and earthquakes, a rock is a natural substance that is made up of solid crystals of different minerals that have been fused together into a solid lump

Jun 22, 2016· Sedimentary Rock Sedimentary rock, one of the 3 major classes of rock comprising the Earth's crust (the others being igneous and metamorphic), is made up of loose, unconsolidated sediment that has been transformed into rock (ie, lithified) during geological history Only about 5% of the Earth's crust is composed of sedimentary rocks, but they cover 70-75% of the exposed surface ,
Coal is a type of organic sedimentary rock formed from the accumulation of plant material that has undergone decomposition in a swampy area It is naturally combustible and is usually mined for use as a fuel It may be brown or black in color and its concentration is dependent on the effect of compaction and changes in the previously existing .
