| 摘 要： | 肖营子岩体为典型的复式岩体，岩性复杂，由多期多次岩浆上侵形成，由2个独立单元和1个序列组成，岩浆活动始于早侏罗世，结束于晚侏罗世，处于由挤压变为拉张的构造环境中，被动侵位特点明显，呈现岩墙扩张模式的就位机制。我们从肖营子岩体形成的构造环境及就位机制来探讨研究肖营子岩体的形成和演化过程，将对研究冀东地区中生代构造岩浆演化历史具有一定的参考意义。

| Abstract: | The Xiaoyingzi terrene is a typical complex massif,which is characterized by the various lithologic combination.It formed during the intruding of multi-periods magma.It is composed by two independent units and one sequences.The magmatic activity begins from the early Jurassic Epoch and end in the late Jurassic Epoch.The structural environment had transferred form compression to expand,and had obvious character of passive emplacement.The emplacement mechanism was dyke emplacement in the expand model. |
