They were formed from the remains of the prolific plant material growing in vast marshy areas in the Carboniferous. The plant remains did not rot in their shallow water environment and formed layer after layer of sediment which was eventually covered with subsequent layers of additional sediments resulting in their compaction and cementation in a process of lithification.

wood-peat-lignite-subbituminous-bituminous-anthracite The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content
Coal deposits form over a long period of time through biological and geological process. Dead plant matter is converted into peat, which is converted into lignite. Lignite is converted into sub-bituminous coal, after that bituminous coal, and lastly anthracite.
Bituminous coal is an organic sedimentary rock formed from the partially decayed remains of plants. Anthracite coal is considered metamorphic rock, and is derived from a bituminous coal protolith. Coal.
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.

Another name for bituminous coal is soft coal.
Bituminous coal is sedimentary! Bituminous coal is sedimentary!
There are 2 types of Bituminous coals:- 1. Bituminous metallurgical coal.2. Bituminous steam coal
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
Bituminous coal is a soft mineral.
Bituminous coal.
Bituminous coal is a soft coal, compared to anthracite coal, a hard coal. Bituminous coal is a long-burning, hot burning source of fuel.
Bituminous coal is sedimentary! Bituminous coal is sedimentary!
Bituminous coal was formed from the remains of plants through compaction by overlying layers of sediments. The plants were part of a marshy or swampy ecosystem where the plant material did not fully degrade after dying because of the conditions of the water into which it fell.
In the US, the anthracite coal seam exists primarily in Eastern Pennsylvania. Across the Appalachian Mountains begins Bituminous coal in the geological area called the Pittsburgh Coal Seam-- - an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Metamorphosis transforms anthracite coal, a hard coal, to Bituminous coal, a soft coal.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
