东濮洼陷是华北盆地南部一个低级次洼陷,形成于地洼阶段余动期(中生代末期),早第三纪沉积建造以含盐、膏层的泥岩、砂岩夹油页岩为特征,是中国东部地洼型含油建造的典型实例。通过对洼陷内丰富的实体化石,遗迹化石和沉积学、地球化学等方面综合分析,认为该区早第三纪时期是以陆相沉积为主,并遭受过短暂的海侵,反映丁东濮洼陷为近海陆缘地洼型盆地的大地构造背景。 Dongpu Sag is a low-level sub-depression in the southern part of the North China Basin. It was formed during the active period of Diwa stage (the end of Mesozoic). Early Triassic sedimentary deposits characterized by mudstone containing salt and gypsum and oil-bearing shale sandstone, Is a typical example of oil-bearing construction in the eastern part of China. Based on the comprehensive analysis of abundant fossils, trace fossils, sedimentology and geochemistry in the sag, it is believed that the area was dominated by continental deposition in the early Tertiary period and suffered a transient transgression which reflected Ding Dong Pu The sag is the tectonic setting of the offshore depression.
