| 摘 要： | 在东营凹陷古近纪沙河街组四段浊流沉积中,发现遗迹化石Paleodictyon的两个遗迹种,即Paleodictyon regulare和Paleodictyon majus;对其围岩地球化学特征的研究则发现有指示海侵发生的甲藻甾烷分子化石发育,据此推测研究区古近纪的沉积与海水相关。

| Abstract: | The ichonofossil Paleodictyon was discoveved in the Paleogene turbiditic deposits in the Dongying Sag,including two ichnospecies,namely,the Paleodictyon regular and Paleodictyon majus.The study on geochemical behavior of the wall rocks revealed that the dinosterane,a sign of marine transgression,was checked out.The both meant that Paleogene sedimentation in the Dongying Sag might be once affected by seawater. |
