渤张断裂带形成于中生代，为剪张性断裂带。中新生代以来渤张断裂带一直活动，并控制中新生代沉积和火山活动。中生代至老第三纪早期（４２Ｍａ 之前）渤张断裂带为右旋走滑的剪张性断裂带，而老第三纪中晚期以来（４２Ｍａ 以来）渤张断裂带转为左旋走滑的剪张性断裂带，并控制了渤海盆地的油气分布和现代的地震活动。近期，沿渤张断裂带地震活动频繁，说明渤张断裂带仍在活动。 Bozhang fault zone formed in the Mesozoic, shear-shear fracture zone. The Bozhang fault zone has been active since the Mesozoic and Cenozoic, and controlled Mesozoic-Cenozoic sedimentation and volcanic activity. The Bozhang fault zone was a shear-dextral strike-slip fault zone in the Mesozoic to early Tertiary (before 42Ma), and the Bozhang fault zone turned to L-strike slip shear since the middle and late Neo-Tertiary (since 42 Ma) Zhang fault zone, and controlled the Bohai Basin oil and gas distribution and modern seismic activity. Recently, the seismic activity along the Bozhang fault zone has been frequent, indicating that the Bozhang fault zone is still active.
