Abstract: The authors discussed the petrogenesis and sedimentary environment of the Permian cherts from the Maihanhada Formation in Haobiru and Hangwula sections of Alxa Right Banner according to the study of the petrologic characteristics,major and rare earth elements. The geochemical test results show that the SiO2 content of the cherts from Haobiru Section is 89.83%-94.16%,with an average of 92.01%;Al/(Al+Fe+Mn) ratio is 0.49-0.65,with an average of 0.56;δCe value is 0.87-0.92,with an average of 0.89. The SiO2 content of the cherts from Hangwula Section is 75.93%-90.14%,with an average of 86.70%;Al/(Al+Fe+Mn) ratio is 0.68-0.78, with an average of 0.73; δCe value is 0.89-0.94, with an average of 0.90. In the Al-Fe-Mn triangular graph, the dots fall into the biochemically deposited area,which indicates its biochemical origin. On the other hand,Al2O3/(Al2O3+Fe2O3)value from Haobiru Section is 0.59-0.78,with an average of 0.71;MnO/TiO2 value is 0.17-0.88,with an average of 0.41;(La/Ce)N value is 1.07-1.25,with an average of 1.16; Ceanom value is -0.059——0.026,with an average of -0.043; Al2O3/(Al2O3+Fe2O3) value from Hangwula Section is 0.78-0.86,with an average of 0.83;MnO/TiO2 value is 0.04-0.40,with an average of 0.16;(La/Ce)N value is 1.02-1.15, with an average of 1.10;Ceanom value is -0.041——0.001, with an average of -0.029. In the discrimination plot of sedimentary environment of cherts,the rocks fall in the continental margin,indicating that the cherts in the study area were deposited in an oxygen-deficient environment. Based on the comprehensive analysis,it can be inferred that the sediments in the study area had been deposited in a coastal shallow marine environment in the continental margin during Early Permian.

Key words: Alxa Right Banner, Permian, chert, geochemistry, sedimentary environment
