摘要(Abstract):
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。
Ichnofabric is sedimentary rock fabric resulti ng from biogenic reworking and is the product of the interaction of physical and b iological processes. Four ichnofabrics have been found in carbonates from Tianzi ling Formation (Upper Devonian) of northern Guangdong, including: Planol ites montanus ichnofabric reflecting limited platform or obturate bay en vironments; Thalassinoides-Planolites ichnofabric formed in pla tform downtidal low energy zone; Skolithos ichnofabric presered in upper and middle tidalflat sediments; Thalassinoides ichnofabric controlled by firmground subtrate. The firmground substrate trace fossil Thalassinoides sp. demarcates discontinuity surface that reflect pauses in sedimentation, generally accompanied by submarine erosion.
