| 摘 要： | 根据岩石组合，分布，接触，包裹关系以及结构和构造，吉林省桦甸地区太古宙花岗质林岩为角闪英云闪长质片麻岩类和黑云母花岗闪长质片麻岩类，角闪英云闪长质片麻岩类为变形前侵入体，黑云母花岗闪长质片麻岩类为同变形侵入体，两类花岗质片麻岩的侵位是晚太古宙近东西向构造变形相伴生的岩浆活动事件。

| Abstract: | According to rock association,distribution,contact relationship of enclosing,texture and structure in the Huadian,Jilin province,the Achean granite gneiss is classified into pladorite gneiss and boitite granite gneiss. The pladorite gneiss is a predeformational intrusive,and the biotite granite gneiss belongs to syndeformational intrusive.The emplacement of two granite gneiss indicates a magmatic activity event which was associated with late Achean a near WE trending tectonical deformation. |
