The division and correlation of strata in the mid-eastern part of Sino-Mongolian border area

In the Sino-Mongolian border area, the Early Precambrian-Cenozoic strata are widely distributed but assigned to different stratigraphic classification systems. Based on the research results of Inner Mongolian strata obtained in recent years, the authors ar-ranged the rock assemblages and fossils of Mongolian strata, carried out stratigraphic division and correlation of the strata in the mideastern part of Sino-Mongolian border area in the light of strata exposed within China's territory. The results show that the strata are continuous, and hence their unified division is practical.
