摘　　要：实测肖尔布拉克寒武系剖面,其厚度达870.9m。在对剖面寒武系沉积相、露头层序地层学等方面分析的基础上认为,该剖面由下至上可以识别出9个三级层序,每个层序均由海侵体系域和高水位体系域构成,由于寒武系时期研究区处于碳酸盐台地环境,缺少低水位体系域。该剖面主要发育碳酸盐台地沉积体系。海平面的升降变化是控制该区沉积相发育和分布的主要因素。The thickness of the Xiaoerbulak Cambrian section is 870.9 m based on a stratigraphic analysis, the Cambrian System at the Xiaorblak section can be divided into 9 third-order sequences, each including a transgression system tract and a high system tract but lacking a lowstand system tract because the Xiaoerbulak section was located on a carbonate platform. Sea level rise and fall were the principal factor that controlled the development of Cambrian depositional system at Xiaoerbulak section.
