Higher anthraxolites

Recent years have been marked by progress in studying the structure of natural X-ray amorphous substances, anthraxolites included, by scanning electron and atomic power microscopy. Integration of the available data on molecular and supramolecular structure of higher anthraxolites from Karelia, Novaya Zemlya, and the Urals allowed elaboration of new classification criteria for solid bitumen, namely, degree of structure perfection and micromineral composition. This approach will help to eliminate disadvantages of traditional investigation of solid bitumen.
