Abstract：On the basis of the composition and appearance study of the ichnofossils in the Lower Permian Taiyuan Formation of Yuzhou and Jiaozuo area of western Henan Province,as well as tests and analyses of the δ13C,δ18O and trace elements in the four kinds of different color fillings of Zoophycos burrows,the results were obtained as follows: (1)The δ13C value ranges between -2‰ and -4‰ in the off-white fillings and between -0.8‰ and -2‰ in the gray fillings. In these two kinds of color fillings,the V/(V+Ni) value is less than 0.46,and the Ce/La value is less than 1.5. These data indicate that the sedimentary environment is characterized with an aerobic condition. (2)The δ13C value ranges generally between -0.2‰ and -0.9‰,and the V/(V+Ni)value is more than 0.46 in the brown fillings,which reflect a dysaerobic sedimentary environment. (3)The δ13C value ranges mostly between 0.2‰ and 1.6‰,and the Ce/La value is more than 1.8 in the black fillings,which reflect an anaerobic sedimentary environment. Based on the comprehensive analysis of above mentioned characteristics,we suggested the responding characteristics model between the three kinds of palaeo-oxygen facies(aerobic,dysaerobic and anaerobic facies)and ichnofossils and their sedimentary setting. This research result can provide some intuitional ichnofossil marks to identify sedimentary environment changes in the carbonate rocks of the Lower Permian Taiyuan Formation in western Henan Province.
