Ultrathin sections of a series of vitrinite concentrates from Carboniferous Taiywan Formation and Permian Shanxi Formation in the eastern part of North China were examined Using transmission electron microscopy. The results revealed that vitrinites of Taiyuan Formation were relatively abundant in submicroliptinite, which was domi nately derived from bacteria and algae. There were significant difference in the concentrations of submicroliptinites in vitrinite between Taiyuan Formation and Shanxi Formation. The chemical properties and behavior of vitrinites in technical processes are related to the concentrations of submicroliptinite in vitrinite. The reasons of differences of vitrinite properties between Taiyuan Formation and Shanxi Formation,vitrinite type, the reasons of anomalous coal properties of Taiyuan Formation have been explained in the level of maceral, submaceral and submicromaceral. The results suggest that abundant algae and bacteria contribution in original plant materials, in the forms of liptinite, liptodetrinite, submicroliptinite and molecular level lipoid materials incorporated in huminite/vitrinite, may be the one important reason for anomalous coal properties of Taiyuan Formation.
