摘　　要：渤海湾盆地铲形正断层及其反向分支断层组合可分为５类，它们的形成过程取决于断层形态。控制断层形态的因素包括岩石力学性质、沉积压实、地层压力等非构造因素。正是这些因素时空复杂变化造成亚样式多样性和千姿百态的断层分布。Patterns of listric normal faults and their reversed branch faults in Bobal gulf basin can be divided into five classes. The variety of the patterns relies mainly on shapes of the faults, instead of on regional tectonic stresses. Shapes of the faults depend on such non--tectonic elements as rock mechanic behaviours, sedimentary compaction and formation pressure. The changes of the elements in time and space result in various patterns of listric normal faults and their reserved branch faults in Bobal gulf basin.
