Abstract

The Late Cenozoic stratigraphic sequence and its information of tectonic evolution are obtained here through the detailed petrostratigraphic and magnetostratigraphic study and research of stratigraphic contact and sedmentary faces of the Cenozoic strata profile, Hejiakouzi area,Ningxia Hui Autonomous Region. The intense Cenozoic tectonic deformation began at 10Ma BP in the Haiyuan-Tongxin Syntaxis, the northeastern margin of Qinghai-Xizang Plateau, and a few deformation events occurred during Late Cenozoic Era.
