煤是研究古生态和古气候的重要标志之一，中国南方中泥盆世晚期已有煤的报道。Quan和Han（1997）在研究了煤中的角质层后，认为煤中的原始石松类（Taeniocrada decheniana）和原始石松类（如Drepanophycus sp.）然而，关于禄劝煤的地质时代和成煤母质的研究还存在一些问题，有必要对禄劝煤的地质时代和成煤母质进行重新研究。
Coal is often considered as one of the important indicators in studying palaeoecology and palaeoclimatology.Late Middle Devonian coals have been reported from South China.Sheng et al.(1992) thought that the precursors of Luquan coals were derived from pteridophyte plants,or bacteria/algae.After studying the cutinites,Quan and Han(1997) thought that Taeniocrada decheniana and primitive lycopsids(such as Drepanophycus sp.) were the principal coal-forming plants.However,there are some ways about the Luquan coals on the geological age and prescursors,it is necessary for us to restudy coals,its geological age and its forming plants.
