Yet they are important as indicators of conditions of related geological 11 processes. The carbon minerals include nanocrystalline graphite, natural analogues of glass-like 12 carbon (GLC) – shungite and impact ultrahigh-pressure GLC, recently discovered 13 ultranocrystalline diamond, as well as natural carbon nanocomposites of diamond, lonsdaleite 14 and graphite. Studying these natural carbon substances using a standard Raman approach with 15 excitation by visible radiation may lead to a significant distortion of the understanding of their 16 phase states.
