Abstract：The abundant ichnofossils were found in the Upper Carboniferous-Lower Permian Taiyuan Formation of Lingchuan area,southeastern Shanxi Province,in which 10 ichnogenus and 14 ichnospecies were distinguished.Common ichnofossils include Zoophycos,Helminthopsis,Planolites,Nereites,Chondrites,Thalassinoides,Rhizocorallium,Ophiomorpha,Palaeophycus and Teichichnus,and the most common ichnofossil is Zoophycos.According to the composition,distribution and occurrence characteristics of ichnofossils,four ichnoassemblages were recognized:(1)Zoophycos-Thalassinoides ichnoassemblage;(2)Planolites-Helminthopsis ichnoassemblage;(3)Zoophycos-Teichichnus ichnoassemblage;(4)Nereites-Chondrites ichnoassemblage.By the analysis of sedimentary characteristics of the host rock of these ichnofossils,it is showed that these ichnoassemblages in the limestone of the Taiyuan Formation mainly distributed respectively in embayment-lagoon(ichnoassemblage 1),the upper shallow sea(ichnoassemblage 2),the middle shallow sea(ichnoassemblage 3)and the lower shallow sea(ichnoassemblage 4).Based on the synthesis analysis of the ichnoassemblages and sedimentary characteristics,this paper puts forward the sedimentary environmental model of ichnoassemblages in the Taiyuan Formation of Lingchuan area.The result will provide the biologic information and basic data for the study of coal and coalbed gas formation palaeoenvironment in the Taiyuan Formation of southeastern Shanxi Province in the future.
