摘要
中国东北地区在早白垩世发育了广泛分布的陆相断陷盆地,石油、煤田勘探已证实这些盆地内蕴藏着丰富的能源资源。东北中生代断陷盆地群的形成与演化是地球深部物质运动所导致的地壳上部垂向运动、层圈伸展拆离与地壳水平运动共同作用的结果,全区具有统一的地壳运动规律,以张性断块构造样式为特色,具有独特的断陷型沉积特征和火山岩发育特征。在伸展拆离背景下发育的同沉积断层控制了断陷的样式、断陷内构造岩相带的展布,对其油气聚集起着重要的控制作用。
During Early Cretaceous continental rift basins were widely distributed in NE China.Petroleum and coal exploration has proven that these basins are rich in energy resource. The formation and evolution of this group resulted from the vertical motion,interlayer extensional decollement and horoizontal motion of the upper crust. They are characterized by extensional fault-blocking and rift-type sedimentary style and more volcanics. The syn-sedimentary master faults controlled the structural style and the distribution of tectonic-litho-factes of rifts,thus further controlling petroleum habitat.
