| 摘 要： | 吉林南部太古宙英云闪长质片麻岩类主要由石英闪长质、英云闪长质、花岗闪长质和奥长花岗质片麻岩组成。地质学、岩相学、地球化学研究表明，它们是同源岩浆通过结晶分异作用形成的，最主要的分离矿物相是角闪石和斜长石。岩浆来源于下地壳角闪质岩石的部分熔融作用。

| 关 键 词： | 英云闪长质片麻岩类，结晶分异作用，分离矿物相，吉林南部 |

| Abstract: | The Archean Tonalitic gneisses in Jilin province consist mainly quartzdioritic-tonalitic-granodioritic-trondhjemitic gneisses. The characteristics of geology,petrography and geochemistry indicate that they were formed by same source magmacrystallization differentiation. The main differentiation mineral facies are hornblende andplagioclase. Magma came from partical melting of amphibolites in deep crust. |
