| 摘 要： | 本文研究吉林省延吉盆地下白垩统2个组中沟鞭藻类及其它藻类组合。其中铜佛寺组二段是延吉盆地下白垩统产沟鞭藻最丰富的层位。Vesperopsis cf．zhaodongensis-Vesperopsis tongfosiensis组合指示的地质时代可能为Hauterivian—Barremian期，代表了淡水-微咸水(偏淡水)的沉积环境，而Filisphaeridium-Sentusidinium组合的时代属于Barremian—Aptian早期，指示的水体环境为淡水-微咸水(偏微咸水)。文中描述了1新种，对Vesperopsis yanjiensis Mao，Wan et Qiao，1999进行了修订。

| Abstract: | The assemblages of dinoflagellates and other algae in 2 formations of the Lower Cretaceous system from the Yanji Basin, Jilin Province, was studied in this article. The most abundant dinoflagellates come from the Member 2 of the Tongfosi formations of the Lower Cretaceous, Yanji Basin. The assemblage of Vesperopsis cf. zhaodongensis Vesperopsis tongfosiensis indicats a Hauterivian Barremian age and freshwater slight salt water(leaning to fresh water) environment; the assemblage of Filisphaeridium Sentusidinium indicats an Early Barremian Aptian age and fresh water light salt water(leaning to light salt water) environment. A new species is described. Vesperopsis yanjiensis Mao,Wan et Qiao, 1999 is emended in this paper. |
