A later report has called this identification, and the very existence of carbyne phases, into question, arguing that the new reflections in the diffraction pattern are due to clay impurities.
Independent confirmatory work is obviously needed … and at the present time white graphite appears to be the carbon analog of polywater".
[3] At the type locality in Bavaria chaoite occurs in graphite bearing gneiss that has undergone shock metamorphism.
[2][3] Minerals associated with chaoite include: graphite, zircon, rutile, pseudobrookite, magnetite, nickeliferous pyrrhotite and baddeleyite.
