Short summary
Vanadium carbides in shungite are shown to be present in several forms, which reflects the distinctive conditions of their formation. An ordered carbon film revealed on the vanadium carbide particles could protect the particles from transformations for a long time. The parageneses of vanadium carbide and roscoelite occur, indicating that roscoelite in shungite rocks may be a secondary mineral formed upon vanadium carbide decomposition.
