Abstract：The Xiaoerbulake Formation(Stage 3, Cambrian Series 2)in the Aksu area of the Tarim Basin is mainly composed of microbial dolostone with its reprehensive section at Sugaitebulake,90 km southwest of Aksu city. This formation can be ideal petroleum reservoirs for its good pores which has been extensively studied. Due to serious diagenesis alteration,however, their features have not been fully identified,which causes difficulty in understanding their formative processes and hampers the petroleum exploration. Here,based on detailed observation on outcrops and thin sections,we identified four types of microbialite fabrics,including thrombolitic fabric,laminated fabric,intraclastic fabric and framestone fabric,and established high-precision vertical evolutionary sequence of microbialites. The thrombolitic and the laminated fabrics can be further subdivided. The Members Ⅰ to Ⅲ are mainly composed of thrombolitic dolostone,thrombolitic-laminated dolostone and laminated dolostone. The Member IV consists of microbial thrombolite mounds,whereas the lower Member V is net-thrombolitic dolostone and the upper Member V intraclastic dolostone and Renalcis framestone. This study reveals that the original fabrics have been affected by dolomitization,recrystallization and dissolution,and the alteration degree of the microbialite fabric is more severe in the lower parts of this formation. The intraclastic fabric has the strongest resistance to diagenesis,followed by the laminated fabric,and then the thrombolitic fabric. The Members Ⅰ to Ⅲ represent tidal flat environments;the Member Ⅳ and the lower Member Ⅴ represent deep subtidal environments;the upper Member Ⅴ represents shallower subtidal environments.
