以华北东部前中生代盆地的几个重要不整合面，以及张夏组的顶面为界面，并以这些地质界面所夹持的沉积地层的厚度变化为依据，反演了前中生代盆地主要地质时期的盆地基底的形态.研究表明，华北东部中元古代盆地由南部和北部两个呈北东一北东东向狭窄条带状展布、向北东和南西向开口的次级盆地组成，并在蓟县、凌原、沈阳北部和像西地区存在有沉降中心;新元古代青白口纪，北部盆地范围缩小，沉降中心转移到宣化一怀柔一带，南部盆地明显扩大，盆底基底向南部和东部倾斜，同时沿现今郑庐断裂的东部盆地开始发育;新元古代震旦纪盆地基本继承了青白口纪盆地的分布范围，但盆地基底的分异更加明显;早古生代盆地分布范围已覆盖整个华北陆块，但盆地的基底具有较大的起伏形态，早古生代早期南北沉陷，中间隆起，呈现出不对称的鞍状，早古生代晚期则中间沉陷，南北隆起，呈向东部开口的簸其状;晚古生代本澳组沉积时期，也为一向东开口的簸其状形态，继承了早古生代晚期的盆地基底形态，太原组沉积时期表现为南部沉降幅度较大，北部则有抬升，一改本澳组沉积时期的基底形态，并保持至晚古生代结束.

英文摘要：

Several major unconformity, as well as the top of Zhangxia formation in the Pre-Mesozoic basin of the eastern part of North China, can be recognized as a plane in corresponding geological period respectively. Based on the thickness change of strata between these geological interfaces, the basement morphology of Pre- Mesozoic in a main geological period can be reflected. The results showed that the Mesoproterozoic basin is composed of two NE-NEE trend sub-basins, in the form of narrow strip openning to NE and SW, and the sub- sidence centers are in Jixian, Lingyuan, the northern of Shenyang and the western Henan Province. In Qing- baikouan period of the Neoproterozoic, the northern part of the basin became smaller, and the subsidence cen- ter transfers to Xuanhua and Huairou; the southern part of the basin began to expand obviously, and the basin basement began tilting to south and east. At the same time, the eastern basin along the Tancheng-Lujiang Fault Zone began to activities. In Sinian period, the basin inherits the distribution range of Qingbaikouan peri-od, but the difference between the two basin basements become to more and more obviously. In Early Paleozo- ic, the basin extended to the whole range of North China Craton, but the basement morphology showed obvious ups and downs. In early period of Early Paleozoic, the Northern and Southern part of basin occurred subsid- ence and the middle began to uplift simuhaneously, the basin showed a asymmetrical saddle shape; In late pe- riod of Early Paleozoic, the middle began to subside and the nortilern and southern part of basin becoIne to up- lift, forming a shape of dustpan opening to east. In the sedimentary period of Benxi formation, Late Paleozoic, the basin also had a shape of dustpan opening to east, inheriting the basement morphology in the later of Early Paleozoic. In the sedimentary period of Taiyuan formation, the basin basement was absolutely changed. The basin basement began to uplift in northern part and subside in the southern part, lasting to the
