Abstract A set of normal terrigenous clastic sedimentary rocks of the first member of Gegenaobao Formation, Upper Carboniferous-Lower Permian, is well developed in Zhalatun area, Inner Mongolia. Base on the analysis of the rock assemblage, composition, vertical variation of strata and sedimentary environment change, the sedimentary rocks of Gegenaobao Formation may be subdivided into one Grade Ⅱ sequence, including three Grade Ⅲ sequences and seven Grade IV sequences. Study on the sequence stratigraphy provides a valuable reference for the Late Paleozoic sedimentary basin formation in Daxinganling region.
