Natural nanostructured carbon materials from large Eurasian deposits were studied by Raman spectroscopy, complemented with high-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). It is shown that natural carbonaceous materials of relatively high metamorphic grade can be divided into shungite-like and anthraxolite-like materials on the basis of the main Raman spectral parameters. Among them, the tortuosity factor characterizes the degree of curvature of the graphene layers in natural nanostructured carbon and is in good agreement with the results of HRTEM.
