10/09/2002 · Crystalline Graphite. It is said that crystalline vein graphite came from crude oil deposits that have transformed into graphite through time, temperature, and pressure. Vein graphite fissures typically measure between 1 cm and 1 m in thickness and usually have a purity of more than 90%.

Vein graphite is formed by fluid deposition, the transformation of oil precursors. The second discernible type of macrocrystalline graphite is socalled "flake graphite". This material is found disseminated in metamorphosed silicarich quartzites, gneisses and marbles. The graphite content in the raw ore can vary from 5 to 40%.
