1892 E. S. Dana J. D. Dana's Syst. Mineral. (ed. 6) 8 Schungite from the Olonets Government, Russia, is a similar amorphous form of carbon intermediate between anthracite and graphite, occurring in phyllite.

1916 Trans. & Proc. Geol. Soc. S. Africa 18 130 Schungite and graphitoid merge into graphite, but the difference is not crystalline merely, for the latter yields graphitic acid on oxidation, while the former do not.

1941 Compt. Rend. (Doklady) de l'Acad. des Sci. de l'URSS XXXIII. 358 Other authors arrived at an opposite conclusion, to the effect that the crystalline phase existing in anthracite and shungite is graphite, but..in a highly dispersed state.

1946 Mineral. Abstr. IX. 202 Eleven analyses of shungite from Shunga, Lake Onega, and other localities in eastern Karelia show C 46–99, ash 1–46, V₂O₅ 0·016–0·77%, &c.

1968 Mineral. Abstr. XIX. 102/1 The use of schungite to obtain combustible gases.

1972 Gloss. Geol. (Amer. Geol. Inst.) 656/2 Shungite, a hard, black, amorphous, coal-like material containing over 98% carbon, found interbedded among Precambrian schists. It is probably the metamorphic equivalent of bitumen, but it may represent merely impure graphite.
