Industrial Minerals Laboratory Manual FLAKE GRAPHITE

Graphite generally occurs as a result of metamorphism (regional or contact) of organic matter in sediments. Flake graphite is assumed to be derived from fine grained sediments rich in organic matter. As metamorphic grade increases, carbonaceous material converts to 'amorphous' graphite.
