Graphite is a metamorphic rock. It is formed from the metamorphism of organic sedimentary rocks, such as coal, under high temperature and pressure.
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
Anthracite is a metamorphic rock commonly called coal ,whose protolith or parent rock is bituminous coal.
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
Anthracite is a metamorphic rock, not a sedimentary or igneous rock. It forms from the metamorphism of bituminous coal, under high pressure and temperature conditions deep within the Earth's crust.

Coal, other than the metamorphic form called anthracite, is an organic sedimentary rock.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
