Lithologic character of Eogene syste is interbedded sandstone and mudstone primarily, including the thin layer oil shale, Neocene- Quaternary system is set of rivers deposits. Based on this, through the reaserch of ateral correlation and distribution characteristics of every structural layers show that: Paleozoic synthem overall thickness of relatively stable.The residual thickness of Mesozoic synthem is difference in the horizontal, Residues in the horizontal thickness of greater difference, to the greatest thickness achieve to 4500m. Eogene syste has obviously fault depression basin deposition characteristic, the thickness of many sags achieve to 3000 m ,from Neocene, the stratum crosswise mop tended to be stable.

在此基础上，通过对各构造层横向对比以及展布特征的研究表明，古生界构造层整体厚度相对稳定，冷武-奥陶系残留厚度在1200m左右，石炭-二叠系残留厚度在800m左右；中生界构造层残留厚度在横向上差异较大，最大厚度达到4500m，其中，下-中三叠统仅发育于南部小部分地区，最大厚度在1000m以上，侏罗系-下白垩统整体具有南厚北薄的展布特征，南部冠北洼陷厚度最大，达到3500m；新生界古近系具明显的断陷式盆地沉积特征，多个洼陷厚度在3000m以上，新近纪以后地层横向展布趋于稳定。

The basin evolution from the Cretaceous to the Palaeogene shows a complete process of rifting development, in which the Lower Cretaceous is theproduct of early rifting and the Upper Cretaceous and the Eogene represent the sediments of thermal subsidence in late rifting stage.

白垩纪—早第三纪盆地演化为一个完整的裂谷发育过程，下白垩统是裂谷早期断陷作用的产物，而上白垩统和下第三系则代表裂谷后期热沉降沉积。

Exhibiting angle unconformities or erosion unconformities in different part of the basin, these surfaces are obvious to be recognized on seismic profiles.T1 conformity, separating Eogene from Neogene, was formed during the whole basin uplifting and erosion by the end of Eogene.T1 unconformity denuded unbearing strata differently, and the deeper and thickest erosion lies on the southern margin of the basin, which reflects the activity of southern Jiangnan paleo-terrene. In conclusion, the major erosion belts extending along NW direction reflects NE-SW compression and slipping caused the Eogene basin uplift and strengthen the earlier NW direction extending low convex, and formed the NW direction extending depress and erosion belts.

古近系和新近系之间的T1不整合面形成于古近纪末期的盆地整体抬升，对下伏地层造成不同程度的剥蚀，沿盆地南缘的剥蚀层位深，剥蚀量大，反映盆地南缘整体相对隆起，与江南古陆的隆起作用有关。T1界面剥蚀带走向以北西向为主，反映了盆地在古近纪末受到了北东－南西向的挤压或压扭作用，该作用造成盆地整体抬升，强化了北西向展布的低凸起，产生了近北西向的洼陷和剥蚀带。
