摘要
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。
The Bozhang fault zone being a transtensional fault zone, was formed in Mesozoic, which has been active and controlled the distribution of Mesozoic and Cenozoic sediments since Mesozoic. During Mesozoic and early Eogene (before 42 Ma), the Bozhang fault zone was right transcurrent transtensional faults, and then it became left transcurrent transtensional faults that controlled the distribution of petroleum and activity of modern earthquake after mid Eogene. Recently,the frequentl activity of earthquakes shows that the Bozhang fault zone remains active and must be looked out carefully.
