The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.
