| 摘 要： | 九华山复式杂岩体由东堡岩体、上菥荻岩体和天台岩体三部分构成。它们之间呈不同形式的侵入接触。各岩体的空间分布、岩浆演化及内部构造等特征均显示它们的独立性。在岩石学、地球化学等方面三者均有明显区别，定位机制也各具特色，东堡岩体以顶蚀作用为主，上菥荻岩体为破火山口沉陷式，天白岩体则为岩墙扩张式定位。

| Abstract: | The Jiuhuashan multiple complex intrusion is composed of the Dongbao intrusion,Shangxidi intrusion and Tiantai intrusion.A distinct intrusive contact relationship is shown among the three.The spatial distribution ,magmatic evolution and internal structure features show their independence unexceptionally,while there exist evident differences in petrology,geochemistry and etc for the three.Each of them has specific emplacement mechanism:the Dongbao intrusioncharacterized by stoping,the Shangxidi intrusion by caldera settlement and the Tiantai intrusion by dike spreading. |
