摘　　要：遗迹组构自Ekdale(1983)首次提出以来,其研究成果主要来自海相沉积,我国是世界上陆相沉积最为发育的地区之一,特别是能源勘探与开发积累了大量宝贵的岩心资料。这些钻孔岩心表面新鲜,垂向连续性好,有利于研究遗迹化石的垂向演化关系,本文在详细观察描述辽河油田古近系近200口井岩心的遗迹化石资料基础之上,首次将陆相岩心遗迹组构划分为2类11种,通过古生态学与沉积学研究相结合,对每种遗迹组构的环境意义进行解释。Ichnofabric research results have come mainly from marine sedimentation since Ekdale (1983) first reported the ichnofabric discovery. China is one of the most developed continental sedimentary regions in the world, and, in particular, a host of cores have been accumulated during energy exploration and development. These cores have fresh surfaces and excellent vertical continuity, which is favorable for the research into the relationship between trace fossils and vertical evolution. The authors of this paper propose for the first time that the ichnofabrics in continental cores can be grouped into 2 major types and 11 subdivisions. Besides, the paper present interpretation for each ichofabiric from the viewpoint of environment based on palaeoecological and sedimentary researches.
