Amorphous Graphite | Asbury Carbons
Amorphous graphite is a seam mineral, not to be confused with a vein mineral. It is formed by the metamorphism of previously existing anthracite coal seams. Proto-coal organic carbon is deposited and converted into anthracite coal followed by low grade metamorphism of the coal. This results in the formation of microcrystalline graphite.
