Amorphous Graphite – Amorphous graphite is commonly found as minute, microcrystalline particles fairly uniformly distributed in weakly metamorphosed rocks, such as slates, or in beds consisting almost entirely of graphite. They are usually metamorphosed coal seams with as much as 80% to 85% graphitic carbon.
