Abstract

Solid bitumens from basaltic rocks from Mítov represent non-graphitised and non-graphitising carbons. Their optical properties, chemical composition, structure and microtexture are similar to some industrial cokes. Their evolution during metamorphic processes appears to be different in comparison with the structural transformation of kerogens during regional metamorphism. Solid bitumens from Mítov are at present the only carbonaceous matter from the geological environment of the Bohemian Massif from which fullerenes have been extracted and determined at noticeable concentrations.
