| 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，新方法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 stud-ied.On the basis of these fossils,combining with rock stratigraphy and sequence stratigraphy,the characteristics of Ear-ly and Middle Jurassic plant assemblage are described,the new strata division is made,and new division project is pro- posed 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. |
