| 摘 要： | 营口-潍坊断裂带是郯庐断裂带中段一部分,自南向北发育潍北、莱州湾、黄河口、渤中、渤东、辽东、辽中等新生代沉积盆地(凹陷)。构造沉降量计算和作图结果表明,上述盆地的沉降史曲线有4种类型,它们对应不同的盆地类型。沿断裂带走向方向构造沉降速率的变化说明,营口-潍坊断裂带新生代以来构造活动自两端向中部逐渐迁移,太平洋板块和印度板块向欧亚板块的汇聚速率和汇聚方向的变化以及菲律宾板块的影响控制了营口-潍坊断裂带新生代构造演化和平均构造沉降量的变化,渤海湾新生代盆地是拉分作用和主动裂谷伸展两种作用共同控制形成的复合型盆地。

| Abstract: | Yingkou-Weifang fault zone is part of central segments of Tanlu fault zone,along which several Cenozoic basins,such as Weibei,Laizhouwan,Huanghekou,Bozhong,Bodong,Liaodong,Liaozhong developed.Tectonic subsidence calculation and mapping demonstrate there are four types of tectonic subsidence curve,each corresponding to different basin style.Tectonic subsidence rate along the fault zone indicates its movement migrated from the two ends to the central.The convergence rates and their directions of Pacific plate and India plate towarding Eurasian plate dominated the tectonic evolution and its average tectonic subsidence change.Bohaiwan Cenozoic basin is a superimposed basin of pull-apart basin and an active extension basin. |
