This graphite consists of porous carbon, nanographite layers, micro- and nanotubes. The porous carbon is classified as macroporous matter with a small amount of mezopores. Evidence for the unusual properties of porous carbon are given: nanographite layers are created at the exposed surface of sample and the nanotubes occurs in the bulk of porous carbon.</p></abstract><kwd-group xml:lang="en"><kwd>Porous carbon</kwd><kwd>Nature nanostructured graphite</kwd><kwd>Graphene</kwd><kwd>Microtubes</kwd><kwd>Nanotubes</kwd><kwd>Magmatic rock</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">H.W.
