Lithochemical features of shungite rocks horizons, Onega structure
The studies of maksovite Immersion Element of Onega structure dome-deposits were carried out.It is developed on different stratigraphic levels of Zaonega Formation of the Palaeoproterozoic (2.0-1.9 Ga).Maksovite were separated for five groups by content of mineral component, namely, supersilites, normosilites, miosilites, gypersilites and siallites
