| Abstract: | Neogene period volcanic activity are mainly the basalt - trachybasalt association in north Chifeng of Inner Mongolia. As a result of research and contrast, the period basic volcanic rock are the production of plate of rift and mantle plume action associated with mantle bulge extension. |
