遗迹化石正在证明其在鉴别和解释事件地层中的作用。风暴沉积含有一套混合的、与能量水平变化相适应的遗迹化石组合 ,两种不同的遗迹群落反映变化着的行为方式对生物所移居的两种连续的 ,但是单个性质不同的生境所作出的反应 :常住的或平常天气的遗迹群落可以作为一种稳定的底栖群落的代表 ,在这一群落里单个的居群达到或接近它们的承载能力 ;而周期性产生的风暴遗迹群落则代表着在一种不稳定的、生态环境恶化的、机械控制的环境下繁盛的机会主义生物的群落。典型的陆源碎屑的风暴沉积中的遗迹群落可以加拿大艾伯塔上白垩统卡迪组中的遗迹群落为例 ,而碳酸盐风暴沉积中的遗迹群落则可以中国华北地台东部上寒武统崮山组中的碳酸盐风暴沉积序列中的遗迹群落为例 ,本文详细介绍这两种类型的成因及结构、构造特点。
Trace fossils are proving their role in identifying and interpreting event formations. Storm deposits contain a mix of remnant fossil assemblages that are adapted to changes in energy levels and two distinct relict communities reflect changing patterns of behavior of two consecutive, but distinct, individual habitats in which the organism migrated Reactions: Resident or common-weather relic communities can be representative of a stable benthic community in which individual populations reach or approximate their carrying capacity; and the cyclically produced storm relic community represents A community of opportunistic creatures that thrive in an unstable, ecologically degraded, mechanically controlled environment. For example, the remnant communities in the typical storm sediments of terrestrial debris can be exemplified by the remnant communities in the Upper Cretaceous Qadi Formation in Alberta, Canada, while the remnant communities in carbonate storm deposits can be dominated by the Upper Cambrian of the North China Platform For example, the remnant communities in the carbonate sedimentation sequence in the Tsaolingshan Formation show the genesis, structure and tectonic features of these two types in detail.
