摘要辽东太子河地区中寒武世地层包括碱厂组和馒头组，属于陆表海沉积.根据岩性组合、沉积旋回、岩相等特征，将该套地层划分出3个三级层序，其中Ⅰ型层序1个，Ⅱ型层序2个，识别出30个副层序.本区凝缩段不发育，层序均由海侵体系域和高水位体系域组成.

Abstract：Middle Cambrian strata in Taizihe area of Eastern Liaoning Province, including Jianchang Formation and Mantou Formation, belongs to epicontinental deposit. According to the features such as lithological combination, sedimentary cycle and lithofacies, the Middle Cambrian stratum is divided into 3 third-order sequences, including 1 type-Ⅰ and 2 type-Ⅱ sequences, and 30 parasequences are identified. The condensed member is not developed and the sequences are all composed of transgressive system tract and high system tract.

Key words： Cambrian sequence stratigraphy sea level change system tract Taizihe area of Liaoning Province
