| Abstract: | In this paper, the authors divide the lithologic unit series of syenite intrusive bodies in Jiashan, Chengde County and classify them as the Jiashan System. Through analysing the petrochemistry,trace elements and REE of the intrusive rocks, we provide the model that the emplacement mechanism of plutonic mass is of the heat-light-balloon-expansive origin. |
