Strata in the studied area are mainly composed of contrastive old and new strata that caused the authors to adopt different ideas and working methods to study them respectively. The old strata prior to the Middle Proterozoic are researched by using a combinative method of tectonics with sedimentology, while the new strata are studied by using a recent stratigraphic method besides a conventional method. Basing on the study on the recent strata, particularly, by the combinative study of Pliocene and Pleistocene, this paper identified the time and characteristics of uplifting of Inner Mongolia Plateau.
