| 摘 要： | 塔里木盆地西南缘艾特沟剖面奇自拉夫组上段产丰富的孢子和疑源类化石，计有孢子２１属４０种、疑源类５属５种。Ｒｅｔｉｓｐｏｒａｌｅｐｉｄｏｐｈｙｔａ和Ａｐｉｃｕｌｉｒｅｔｕｓｉｓｐｏｒａｈｕｎａｎｅｎｓｉｓ等国内外晚泥盆世典型分子在当前组合中出现表明奇自拉夫组上段时代应为晚泥盆世法门期。海相疑源类的发现从根本上否定了以往所认为的奇自拉夫组为陆相沉积的推测。化石保存状况及岩相分析说明奇自拉夫组上段为滨海相沉积。

| Abstract: | The present paper deals with the spores and acritachs from the upper part of the Qizilafu Formation of the Aitegou section, Shache County, Southwest Tarim Basin. 40 spore species assigned to 21 genera and 5 acritach species to 5 genera are first recognized in this area. Comparisons of the present spore assemblage with those of other areas suggest a Late Devonian (Famenian) age for the upper part of the Qizilafu Formation. |
