| Abstract: | Twenty two ichnotaxa have been found in the Silurian and Carboniferous turbidites of the Tianshan orogenic belt and the Triassic turbidites of the East Kunlun West Qinling orogenic belt of northwestern China. They are Helminthopsis hieroglyphica, Neonereites biserialis, N. uniserialis, Palaeophycus isp. , P. serratus, P. striatus, P. tubularis, Paleodictyon imperfectum, Phycodes circinnatum, Phycosiphon incertum, Planolites annularis, P. beverleyensis, P. montanus, Rhizocorallium isp. , Scalarituba missouriensis, Skolithos isp., ? Spirorhaphe isp. , Sublorenzinia isp. , Tambia isp. , Taphrhelminthopsis auricularis, Teichichnus isp., and Thalassinoides isp. These trace fossils can be grouped into four ichno assemblages: Phycosiphon Palaeophycus ichno assemblage representing turbidity current deposits of a restricted anoxic deep sea basin, Neonereites Scalarituba ichno assemblage representing the upper middle turbidity fan deposits of a pelagic and hemipelagic environment., Paleodictyon ichno assemblage representing the middle lower turbidity fan deposits of an oceanic archipelago, and Phycodes Skolithos ichno assemblage showing middle turbidity fan environments. |
