摘要：

本文较系统地研究了中国东部济阳坳陷车镇与沾化凹陷古近系遗迹化石的组成、分布和产状特征及其沉积环境，提出了三种古湖泊沉积环境中的遗迹化石群落：（1）Scoyenia遗迹群落，由?Scoyenia、Beaconites、Taenidium、Planolites、Palaeophycus、Macaronichnus、Gordia、Skolithos、Ophiomorpha、Sagittichnus和Favreina等遗迹属组成，代表了经常干旱的滨浅湖或泛滥平原上的极浅水沉积环境；（2）Mermoides遗迹群落，以Mermoides、Neonereites、Planolites 、Helminthopsis、 Helminthopsis、Helminthoidichnites、Vagrichnus和Cochlichnus等遗迹属为特征，指示半深湖或较深水湖沉积环境；（3）Macaronichnus遗迹群落，主要组成分子有Macaronichnus、Planolites、Palaeophycus、Skolithos 、Monocraterion、Arenicolites、Margaritichnus、cf.?Thalassinoides?等遗迹属和须根迹，反映了中等能量与低能水体交替变化的沉积环境。

Abstract:

Based on the systematic research of the composition, distribution and taphonomy characteristics of trace fossils in the Shahejie Formation of Paleogene in Chezhen and Zhanhua Sags, Jiyang Depression , Shandong province, this paper suggests three kinds of ichnocoenoses in the paleo-lacustrine sediments: (1) Scoyenia Ichnocoenosis, which consists of Scoyenia, Beaconites, Taenidium, Planolites, Palaeophycus, Macaronichnus, Gordia, Skolithos, Ophiomorpha, Sagittichnus and Favreina and so on, may serve to represent a regularly desiccated sandy and muddy shore and extremely shallow lacustrine sedimentary environment;(2)Mermoides Ichnocoenosis, which is characterized by such deeper water pattern fossils as Mermoides, Neonereites, Planolites, Helminthopsis, Helminthoidichnites, Vagrichnus and Cochlichnus, may display deeper lacustrine sedimentary environment;(3) Macaronichnus Ichnocoenosis, which mainly includes some common trace fossils as Macaronichnus, Planolites, Palaeophycus, Skolithos, Monocraterion, Arenicolites, Brevitubus, Margaritichnus, cf.Thalassinoides and other Rhizoliths, generally occurs in the interchange sedimentary setting between middle and low energy water bodies, such as lacustrine delta plain, delta-front sand bar, sand bank and storm sediments in the shallow lacustrine environment, and middle to outer fan turbidite deposits in the deeper lacustrine environment.
