Einteilung der psychischen StörungenNuclear magnetic resonance analyses, elemental abundances, and isotopic studies provide further constraints on the nature of the organic material, and data from these studies are consistent with a humic acid rather than an oil origin. In addition, the overall tabular shape of primary uranium orebodi

Die Ursachen der Geisteskrankheiten, USSR). Its chemical structure differs considerably in comparison with other types of solid bitumen. Structural inhomogeneity is a characteristic feature of this carbonaceous matter. The structure of shungite is a result of some process which oxidized primary organic matter of probably algal origin, and of the conditions of regional metamorphism.

According to their genesis, and time of formation, the bitumen can be divided into the following types:.The textural-structural characteristics of organic matter and bitumen in stratabound ore deposits help in understanding their genesis and are useful in exploration.
