Natural Flake Graphite | Asbury Carbons

This is a high pressure and high temperature environment. Graphite flake may form under pressures of 75,000 psi (1GPa) and 1380 deg. F (750 deg. C). Since graphite is a form of carbon, and all carbon oxidizes at high temperature, a geologic environment in which nascent or otherwise reactive oxygen is present will preclude the formation of graphite.
