在整个黄河三角洲地区和莱洲湾南岸晚更新世以来经历了海陆相沉积的频繁交替,本文通过古地磁和14C测年资料对不同钻孔的晚更新世地层进行了精确的年代对比,揭示了不同时期的沉积序列。并通过27口钻井的联合对比剖面,揭示出本区晚更新世以来的新构造运动表现为二凹夹一隆的构造特征,对黄河三角洲发育位置和沉降特征有强烈的控制作用。 Throughout the Yellow River Delta and the south bank of Laizhou Bay since the late Pleistocene experienced frequent sea-land facies alternation, this paper by paleomagnetic and 14C dating data for different borehole Late Pleistocene stratigraphy accurate dating reveals Sedimentary sequences of different periods. Based on the joint contrast profile of 27 drilling wells, it is revealed that the Neotectonic movement in the area since the late Pleistocene shows the structural characteristics of Erjinkianlong, which has a strong control over the development and settlement characteristics of the Yellow River Delta.
