Fullerene C60 occurs at extremely low concentration (0.2—0.3 ppm) in hard solid bitumen that was accumulated in the pillow lava bodies exposed at Mítov (Teplá-Barrandian Neo-proterozoic of the Bohemian Massif). No higher fullerenes were documented. The C60 fullerene and its precursors are present in non-graphitic and non-graphitizable carbonaceous matter. Inclusions of fullerene are found embedded within glass-like carbons that are found within the pillow lava bodies. Rare fullerenes in Mítov were probably preserved in the closed micropores and mesopores of the glass-like, solid bitumen. Pyrolysis of biogenic PAHs precursors seems a plausible way to form fullerenes in geological environments.
