摘要
简要论述了Macaronichnus遗迹属的基本特征及包含它的两种遗迹组构的组成与古环境意义 .其中海相沉积中的Macaronichnus Ophiomorpha遗迹组构大多产于与潮汐作用有关的临滨环境 ,而陆相沉积中的Macaronichnus Monocraterion遗迹组构则形成于河流三角洲前缘和浅湖上部环境 ;同时 。
This paper briefly deals with the dominant characteristics of the ichnogenus Macaronichnus and its two constituents of the Ichnofabric and the palaeoenvironmental significance,in which Macaronichnus?Ophiomorpha Ichnofabric in the marine facies deposits is interpreted as formed in the shoreface environment relative to tidal action,while Macaronichnus?Monocraterion Ichnofabric in the terrestrial facies deposits is suggested as occurred in the fluvial delta?front and upper shallow lacustrine.At the same time,the differences between the Ichnofabrics are comparatively analyzed.
