遗迹组构是由生物成因改造的沉积岩组构,它是物理过程和生物过程相互作用的产物。本文在广东韶关晚泥盆世天子岭组碳酸盐岩沉积中建立了4个遗迹组构,即反映局限台地或封闭海湾环境的Planolitesmontanus遗迹组构,反映台地潮下低能环境的Thalassinoides—Planolites遗迹组构,反映潮上-潮间环境的Skolithos遗迹组构和受固底底质控制的Thalassinoides遗迹组构。对遗迹化石和生物扰动构造进行阶层分析,从中识别出受固底底质控制的遗迹化石Thalassinoidessp .,这类遗迹化石常常代表层序地层学中的重要界面。
The relic structure is a sedimentary rock structure transformed by biological genesis, which is the product of the interaction between the physical process and the biological process. In this paper, four tracery structures were established in the carbonate rocks of the Late Devonian Tianziling Formation, Shaoguan, Guangdong Province, namely the Planolitesmontanus relic structure reflecting the confined or closed gulf environment, the Thalassinoides-Planolites relic Structure, the skolithos relic fabric that reflects the tidal-tidal environment and the Thalassinoides relic fabric that is controlled by the solid substrate. Hierarchical analysis of the remnant fossil and bioturbation structures identified the Thalassinoidessp, a fossil that is controlled by the solid-bottomed sediments, which often represent important interfaces in sequence stratigraphy.
