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。
In the early Cretaceous, northeastern China developed widespread continental rift basins. Oil and coal exploration have confirmed the abundant energy resources in these basins. The formation and evolution of the Mesozoic rift basin in the northeastern China are the result of the interaction of the vertical movement of the upper crust, the extension and detachment of the ring and the horizontal movement of the crust caused by deep earth movement. The whole region has a uniform crustal movement pattern, Fault block structure style features, with unique faulted sedimentary characteristics and volcanic rock development characteristics. The synsedimentary faults developed in the context of extension and detachment control the pattern of fault depression and the distribution of structural lithofacies within the fault depression plays an important role in controlling the hydrocarbon accumulation.
