Abstract
Yangyuan-Yuxian basin is located in the eastern margin of the Datong basin. Because a large
number of mammalian fossils and ancient human remains were found and excavated at NIHEWAN
and the surrounding areas of the eastern basin, it became an important base of geo ecological
changes and the origin and evolution study of human of China and Central Asia. Why this land,
which is so suitable for mammalian faunas to produce and inhabit, becomes hilly areas with roll-
ing hills, criss-cross ravines and gullies and bad environment in a very short period of time? Re-
search thinks, this is closely related to the uplift of Zhangjiakou-Xuanhua region since Yanshan
movement and the rifting of Fen Wei rift system since joy mountain movement. They are con-
trolled and influenced by the deep upper mantle plume. And the changes of the natural environ-
ment, such as crustal deformation, magmatic activity, caused frequent disasters, climate change,
environmental change, ecological variation, and so on. This paper, based on the theory of mantle
plume (mantle branch structur
