| Abstract: | Sinian is one of the most important stage of development of passive continental margin basin in Tarim Basin.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 Ⅱ to 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，The lower section of Sugaitbulak Fm.consists of the tidal flat，shore dune，shore and foreshore and outer upper shore sedimentation； while the upper the nearshore，tidal channel outer shore and open shalf ramp and slope sedimentation； The terrestrial eruption of the basalt rhyolite and tuff，which are used to interpolation of diabase dyke，suggested as the continental break up product in the development of passive continental margin basin of the Sinian to the early Palaeozoic stage. |
