| 摘 要： | 新疆叶城县南部赛力亚克达坂一带位于西昆仑造山带。由于自然条件恶劣,交通不便,野外地质调查与研究十分困难。对赛力亚克达坂群的时代确定主要是依据新芦木Neocalamitessp.和双壳类Eumorphotissp.、Claraiasp.等大化石,一直没有微体古生物方面的证据。最近,笔者在该套地层中采集到Limatulasporites,Alisporites等孢粉化石,为该套地层时代的确定、西昆仑地层的对比、麻扎-康西瓦构造带演化研究提供了微体古生物方面的依据。

| Abstract: | The Saliyakedaban area, southern Yecheng County, Xinjiang is situated in the Western Kunlun Mountains, where field geological survey and research are greatly difficult, because natural conditions of this area are very bad, and transportation is inconvenient. The determination of the stratigraphic age of the Sailiyakedaban Group was mainly based on Neocalamites sp., Eumorphotis sp. and Claraia sp., but no evidence of microfossils has been obtained. Sporopollen assemblage of Limatulasporites,Alisporites was found in the Sailiyakedaban Group recently, which provides important basis for the determination of the age of the Sailiyakedaban Group, stratigraphic division and correlation in the West Kunlun orogen and research on the geological evolution in the Mazar-Kangxiwar suture zone. |
