- Аннотация: The results of coal petrographic geochemical studies of the organic matter(OM)from Tutleim Formation rocks in the area of the Em-Egovskaya summit are presented.Five macerals that compose OM of the gormation are identified: "standart"bituminite, "atypical bituminite",radiolarian OM, alginite, and vitrinite, as well as bituminouss films being the products of the original OM transformation.The metamorphism in macerals during catagenesis is discribed and the order of their entry into the generation phaseis established.It is showen that alginite is transformed first, then"standart"bituminite, "atypical" bituminite, and last radiolarian OM.The results are confirmed by the laboratory modeling of the further OM transformation.New bitumens are formed with different fluorescent properties compaired to the original ones.These results togetherwith the study of alternation in the compositions of both macerals and bitumens enable the assemtnt of the contributions by individual OM microcomponents to the process of petroleum hydrocarbon generation.
