However, Taihang Mountain has already risen in Indo-Chinese epoch,so the farthest place of the east boundary can only be Taihang Mountain.

同时，山西和河南等地的侏罗系残留地层与鄂尔多斯可以进行对比，可以推断，盆地的东界在吕梁山以东，而太行山在印支期已经隆起，所以盆地的东界最远只能达太行山。

In Jurassic, the western, eastern and northern boundary of the basin had changed in varying degrees, except the south- Qinling orogenic belt rising in Indo-Chinese epoch, which is an always limited boundary. The western of the basin is limited by west-edge thrust nappe belt which formed in early and mid Jurassic.
