| 摘 要： | 通过同位素年龄、岩石化学、造岩矿物、副矿物、稀土元素、成岩物理化学条件和自变质作用等方面,讨论了诸广山复式岩体中斑状和小斑状二云母花岗岩的期次划分。同时,根据花岗岩的若干地质和地球化学特征变化规律,运用微量元素定量模式,探讨了花岗岩浆的演化机制。

| Abstract: | By the study of isotopic age,rock chemistry,rock-forming minerals,accessory minerals,REE,diagenetic physical and chemical environment as well as self-metamorphism,the paper discusses the partition of rocks for the porphyritic and small-porphyritic two-mica granite in Zhuguangshan granite complex. According to the variation of geological and geochemical characteristics in the granites,the evolution process of granite magma has been resrarched by the quantitative method of trace element. |
