| 摘 要： | 本文论述了牟平—乳山地区花岗岩的岩石学特征,副矿物组合特征,尤其是锆石特征,副矿物的化学成分与微量元素及稀土元素组合特征,并在此基础上探讨了花岗岩的成因。本区花岗岩的成因是复杂的,既有花岗岩化作用(交代作用)和深熔作用形成的花岗岩,又有岩浆分异结晶作用的产物。

| Abstract: | In this paper the petrological characteristics of the granitic rocks in the Moupin-Rushan region are presented; the features of the accessory mineral assemblage, especially those of zircon and those in terms of chemistry, trace and rare earth elements of the accessory minerals are expounded. On this basis, the origins of the granites are discussed. It is suggested that the genesis of the granites in the region is complex in that they are formed by granitization (metasomatism), anatexis and magmatic fraction... |
