| 摘 要： | 本文对延吉盆地介形类化石的分布规律进行了研究，发现介形类化石的演化可分为三个阶段，据此将其划分为三个介形类化石带，六个亚带，通过东西部露头与钻井岩心中介形类对比，解决了盆地内东，西部露头对比问题，建立了新的地层层序。

| Abstract: | This paper studies the distribution regularity of ostracode fossile in Yanji basin,and divides the evolution of ostracode fossile into three periods,based on these,three ostra-code fossile zones and six subzones are divided.Making a comparison of outcrop in east andwest parts to cores,compar;on of outcrop in east and west parts is realized and new forma-tion sequance is established. |

| Keywords: | Yanji basin Cretaceous Ostracode fossile Distribution regularity. |
