Abstract
The transmission Electron Microscopy examination of ultrathin sections of a series of Carboniferous Taiyuan Formation and Permian Shanxi Formation vitrinites collected from 18 mining areas of the eastern port of North China, has revealed that vitrinites of Taiyuan Formation are rich in submicroliptinite, which is dominahtly derived from bacteria and algae. There is significant difference in the amount of submicroliptinites in vitrinite between Taiyuan Formation and Shanxi Formation. The amounts of submicroliptinite are related to chemical properties and behaviors in technical processes of vitrinite. The reasons of differences in vitrinite properties between Taiyuan Formation and Shanxi Formation have been explained in the level of maceral, submaceral and submicromaceral. The reasons of anomalous coal properties of Taiyuan Formation and reductivity of humic coal have been analysed and discussed. The results suggest that abundant algae and bacteria contribution, in the forms of liptinite, submicroliptinite and molecular level lipoid materials incorpotated in huminite/vitrinite, may be one of the important reasons for anomalous coal properties of Taiyuan Formation.
