The current paper presents the first attempt to recreate the origin ofshungite carbon at microscopic level basing on knowledge accumulated bygraphene science. The main idea of our approach is that different efficacy ofchemical transformation of primarily generated graphene flakes (aromaticlamellae in geological literature), subjected to oxidation/reduction reactionsin aqueous environment, lays the foundation of the difference in graphite andshungite derivation under natural conditions. Low-efficient reactions in thecase of graphite do not prevent from the formation of large graphite layerswhile high-efficient oxidation/reduction transforms the initial graphene flakesinto those of reduced graphene oxide of ~1nm in size. Multistage aggregation ofthese basic structural units, attributed to graphene quantum dots of shungite,leads to the fractal structure of shungite carbon thus exhibiting it as a newallotrope of natural carbon. The suggested microscopic view has finds areliable confirmation when analyzing the available empirical data.
