摘要
运用煤岩分析及植物残体分析方法，结合电子显微技术（ＴＥＭ和ＳＥＭ），对云南第三纪浅色褐煤的微结构特征、成煤植物组成、孢粉组合等进行了研究，并将成色褐煤与深色褐煤分层及不同植物成因的泥炭进行了对比研究。在此基础上对浅色褐煤的成煤物质及煤的成因提出新的认识。
etaited studies on the microstructure,coal-forming plants and sporopollen assemblage of light brown coal from Tertiary in Yunan province are made in this paper by the methods of coal petrology,phyteral analysis and TEM & SEM technology. We also make a study of light brown coal compared with the dark brown coals and peats derived from different plants. On the basis of the above studies,we put forward a new theory on the coal-forming plants and genesis of the light brown coal in Yunnan Province.
