| 摘 要： | 利用超薄切片透射电镜分析技术，对华北太原组和山西组煤中镜质组的超微结构和组分进行了分析，确认太原组镜质组中含有较丰富的超微类脂体，且超微类脂体主要来自菌藻类，山西组和太原组镜质组中超微类脂体数量存在明显差异。证实镜质体中超微类脂体数量和其化学性质紧密相关。从超微组分层次解释了山西组和太原组镜质组性质差异的原因，并分析讨论了太原组煤性质异常性的原因和煤还原程度问题，提出成煤过程中明显菌藻类低等生物贡献是太原组煤性质异常的一个重要原因。

| 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. |
