摘要: 研究了采自吐哈盆地西南部早、中侏罗世的植物化石,在鉴定其种属的基础上,结合岩石地层学和层序地层学方法,描述了早、中侏罗世的植物组合特征,对其地层时代进行了新的厘定,提出了新的地层划分方案。新的划分方案不同于前人的划分结果,新方案一方面 依据了新采集的植物化石资料,同时考虑到了野外实际工作的可操作性。此外,还提出了根据煤层发育程度、生物化石群、不整合面和岩性等特征,识别标志层的方法。

Abstract: The plant fossils of the Early and Middle Jurassic in southwestern part of Turpan-Hami basin are studied. On the basis of these fossils, combining with rock stratigraphy and sequence stratigraphy, the characteristics of Early and Middle Jurassic plant assemblage are described, the new strata drvision is made, and new division project is proposed herein, based on these new plant fossil materials and taking into account for easy operation in the field. Also, this paper presents marker bed feature and recognition method for coal seam,bio-fossil group,unconformity and lithology, etc.

Key words: Turpan-Hami basin, Jurassic, stratigraphic division, plant, fossil
