The Ordos Basin is a large-scale sedimentary basin in Northwest China. From bottom up, the hydrostratigraphic units in the basin are pre-Cambrian metamorphic rocks, lower-Paleozoic carbonate rocks, upper-Paleozoic to Mesozoic clastic rocks and Cenozoic deposits.

鄂尔多斯盆地是我国西北地区的大型构造沉积盆地，以前寒武系变质岩为基底，依次沉积了下古生界碳酸盐岩、上古生界一中生界碎屑岩和各种成因的新生界，总厚度达6000m。

Results of inversion show that pre-Tertiary deposition in Dongying depression is controlled with westnorth structures. Archaean group is the crystal basement of Dongying depression, which is a north steep and south gentle rift subsidence basin striking from eastnorth to near westeast, and the deepest position is up to 12000 m at the area of Xianhe and Xinzhen. The configuration of Ordovician of lower Palaeozoic system highly inherits that of Archaean group and both have a strong consistency. The configuration of Mesozoic inherits that of lower Palaeozoic system as a whole, but filling and local reconstruction are distinct, and the scope of Dongying depression has obviously decreased.

Based on analysis for paleostructural characteristics of above four areas,the paper proposed that there developed a series of paleostructure belts under the background of regional uplifting in latest Mesozoic at the front of south Qilian Mt,and those paleostructures are characterized by NWNNWstriked anticlines and synclines,whose wavelengths are 15～20 km and middlescaled. At the same time,the paper also points out that most areas in western China are lack of upper Cretaceous,which implies the existence of a broad Late Cretaceous plateau in central Asia.
