Crystalline vein graphite can be recognized by its light metallic sheen and needle-like particle morphology. It is found in fissures, fractures, or cavities transversing igneous and metamorphic rocks through pyrolysis of carbon-bearing gases. It is the most pure and highest level of crystallinity of the natural graphites, as well as the most rare. |
