Abstract
The geologic structure of shungite deposits in Karelia and the composition of shungites are considered. Modern models for the genesis of these rocks are presented. The specific features of the rocks are analyzed in terms of a recently proposed model for the genesis and evolution of shungites, implying the formation of soot during the combustion of deep-seated methane under oxygen deficiency conditions. It is concluded that the model is constructive and does not contradict factual data.
