文中对江西二叠系乐平组的角质层化石作了描述,并与河南小风口组(下石盒子组)的标志性植物化石华夏单网羊齿(Gigantonoclea cathaysiana)的模式标本进行比较,确定二者为同种,这就为华南与华北的非海相二叠纪含煤地层建立了对比的基础,在地层对比上是一个极有意义的重大进展。对角质层化石的层位江西乐平组老山段下亚段作了较详细讨论,论证其时代应属冷坞期(Capitanian)而不是吴家坪期。
In this paper, the cuticle fossils in the Leping Formation of Permian in Jiangxi Province are described and compared with the model specimens of the iconic plant fossil Gigantonoclea cathaysiana in Xiaofukou Formation (Xiashihezi Formation) of Henan Province, For the same species, this is the basis for the comparison of the non-marine Permian coal-bearing strata in South China and North China. It is a significant and significant progress in stratigraphic comparison. The stratum fauna of the stratum fossils was discussed in more detail in the lower section of the Laoshan section of Leping Formation in Jiangxi Province, demonstrating that its era should belong to the Capitanian period rather than the Wujiaping period.
