Fullerenes C(sub)60 and C(sub)70, the all-carbon molecules with closed-cage structures were discovered in 1990 in shungite from the Kola peninsula. Subsequent discoveries in terrestrial materials include a fulgurite from Colorado, clays and marls from several locations on the Cretaceous-Tertiary boundary, and carbon-rich breccias from the Sudbury impact structure. A search for fullerenes in the carbon-rich materials anthraxolite, shungite, and thucholite, however, failed to find them.
