摘要
本文对承德县甲山正长岩体进行了岩石谱系单位划分，归并为甲山序列；对岩体的岩石化学、微量元素、稀土元素进行分析，提出深成岩体就位机制为热轻气球膨胀型式的模式。
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.
