| 摘 要： | 柴家庄、八卦山和天子山花岗岩体空间上紧密共生,岩性均为二长花岗岩,岩石具富硅、过铝、贫钙的地球化学特征,属钙碱性系列。3个岩体的大离子亲石元素蛛网图和稀土元素配分曲线相关性均较好。3个岩体受印支晚期断裂构造控制,成岩时代相近,是同源岩浆演化不同期次的产物,应统称为柴家庄—八卦山—天子山岩浆带。

| Abstract: | Chaijiazhang,Tianzishan and Baguashan granites closely accrete in space.They are all adamellites.The geochemical character is rich SiO_2,over-saturated Al_2O_3 and poor CaO.They all belong to calc-alkalic series.Trace elements distribution and REE distribution patterns all show good pertinency.These three granites were controlled by Indosinian fault structure and were results of the same magma's crystallization and evolution in different stages.They also have similar intrusion ages,so they should be named together as Chaijiazhuang-Baguashan-Tianzishan magma belt. |
