Shungite can be low-carbon (5% C), medium-carbon (5-25% C) and high-carbon (25-80% C) percent by weight of carbon and the carbon base of shungite is a multilayered fullerene-like globule with a diameter of 10-30 nm. Graphene is Carbon in 2 dimensional form. It is monolayer carbon molecules in a flat, 2 dimensional sheet.
