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.

Sedimentary rock - Sedimentary rock - Coal: Coals are the most abundant organic-rich sedimentary rock. They consist of undecayed organic matter that either accumulated in place or was transported from elsewhere to the depositional site. The most important organic component in coal is humus.

Oct 02, 2019 Claystones are composed of clay-sized grains. Most limestones in coal-bearing rocks are fine-grained, but coarse varieties do occasionally occur. Mineral Composition. The general composition of sand-sized and larger grains can be directly observed. The particles may be composed of common sedimentary minerals or other kinds of rock fragments.

Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and

Oct 22, 2019 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 things. These rocks are often called clastic sedimentary rocks.

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 Rocks:

Organic sedimentary rock- This type of rock rises in the sea as microscopic organisms. It forms when a large number of living organisms pile up, die and become compressed and thereafter, cemented forming rock. With a small scale of compaction, it becomes Peat. After much deeper and longer burial, it becomes Coal.
