A STUDY ON PERMIAN INSHUANGJINGZI SECTION, KELAMEILI AREA OF JUNGGAR BASIN.

通过对准噶尔盆地克拉美丽地区双井子剖面二叠系的孢粉化石分布及组合特征分析对比，结合磁性地层和同位素年龄的研究结果，认为平地泉组的地质时代为晚二叠世中期的中Ｋａｚａｎｉａｎ期至中Ｔａｔａｒｉａｎ期。

y means of analysis and comparison of distribution and asseinblage char-acteristics of Permian sporopollen fossils in Shuangjingzi section in Kelameih area of Jung-gar basin. it is considered that the geologic time of Pingdiquan formation is Middle Kazani-an-Middle Tatarian period in middle period of late Permian, combining with the study re-sults of magnetic bed and isotopic age.
