摘要:

渤海湾盆地早第三纪存在独特的构造格局,呈以渤中凹陷为中心的放射状断裂体系和环状断裂体系,这种格局是地幔物质底辟作用的结果。盆地自早第三纪以来经历了两次构造热冷缩沉降过程。地幔初始隆起时,地壳减薄盆地进入断层控制的沉降阶段,之后地幔温度降低,盆地进入热冷缩沉降阶段

Abstract:

An unique structural framework of Early Tertiary exists in Bohai Bay Basin,its radiate fault system and circular fault system are distributed around Bozhong Depression.The framework resulted from mantle diapirism.The Bohai Bay Basin has undergone two faulting thermal contraction stages ever since Early Tertiary.When the mantle swelled initially,the earth crust thinned,the basin began its faulting-controlled subsidence.Then the mantle’s temperature decreased,the basin entered its thermal contraction subsidence.
