Anthracite is metamorphosed bituminous coal, a coal with the highest percentage of carbon of the coal varieties.
Coal when subject to mild metamorphism turns into Anthracite, in which the carbon content is between 92% and 98%. If squeezed and heated still further, the coal will transform into graphite and of cause if the taken to extremes diamond will be produced, but that would require the coal to be taken deep into the earth's mantle.
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.

Anthracite coal is primarily found in the United States, with large deposits located in states such as Pennsylvania, West Virginia, and Kentucky. It is a type of coal that is known for its high carbon content and low impurities.

Anthracite, a more dense variety of coal is found in only a few countries. China has the majority but other countries such as Russia, Ukraine, North Korea, Vietnam and the UK have deposits.
