Is anthracite an igneous metamorphic or sedimentary?

What are the varieties of coal formed inside the earth?
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
How anthracite forms?
Anthracite, also known as anthracite coal, is formed through metamorphism. Anthracite needs pressure to form, as well temperatures of at least 250 degrees Celsius.
A metamorphic rock formed from coal?
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
How is coal created and where does coal it come from?
coal is created by the deposition and compaction of huge plant(organic) material deposited into a basin,with the increasing depth the high rank of coal is formed. The order is:- peat>lignite>bituminous>anthracite Peat is formed at shallow depth and on moving downward anthracite is formed at greater depth.
How does metamorphism change coal into anthracite?
Actually anthracite is a variety of coal.
By which process is anthracite coal formed from bituminous coal?
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.
Is Anthracite coal igneous metamorphic or sedimentary?
Anthracite Coal is a metamorphic rock.
