摘    要:本文系统地研究了塔里木盆地北缘侏罗纪的孢子花粉。共发现孢粉化石52属90种,以及藻类化石2属2种。建立侏罗纪的孢粉组合序列如下:(1)Disacciatrileti-Cyathidites组合(早侏罗世早期阿合组),(2)Cyathidites-Cibotiumspora-Disacciatrileti组合(早侏罗世晚期阳霞组),(3)Cyathidites-Neoraistrickia-Disacciatrileti组合(中侏罗世早期克孜勒努尔组),(4)Cyathidites-Clasopolis组合(中侏罗世晚期恰克马克组)。根据孢粉组合特征讨论了地质时代,同时探讨了古植被和古气候的意义。

关 键 词:孢粉  侏罗纪  塔里木盆地北缘

Abstract:The present paper deals with the Jurassic palynological assemblages from the northern margin in the Tarim Basin of Xinjiang, NW China. Totally, 90 species of 52 genera of spores and pollen and 2 species of 2 genera of fossil algae, which may be divided in ascending order into the following four palynological assemblages based on their characteristics and changes in content.
Keywords:Palynomorphs    Jurassic    Tarim Basin
