Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
Anthracite is a form of coal, coal is primary carbon, and carbon is black.

The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
