摘要

 Based on the measurement and analysis of section of Sugaitbulak Fm. （Z2s） of the Upper Sinian at Xianerbulak of Aksu with regarded to lithofacies, sequence stratigraphy and facies succession fabric features and the orderly stacking patterns, the uplift- corrosion unconformity in the lower, transgressive onlap unconformity between upper and lower section and exposure meteoric-formation and facies change-correlative conformity on the top of Sugaitbulak Fm. （Z2s）have been identified as Ⅱto Ⅲ（Ⅳ） sequence boundary surfaces. The sedimentation environment of Sugaitbulak Fm. （Z2s） is believed to the coastal to shore to open shalf-ramp and slope clastic system.
