摘要
吉林南部太古宙辉石花岗岩类具有与英云闪长质─奥长花岗岩质－花岗闪长质片麻岩（ＴＴＧ）及深熔钾长花岗岩不同的特征，并不是ＴＴＧ岩系的一部分。地质学、岩石学及地球化学研究表明，该辉石花岗岩类是壳源岩浆结晶分异作用的结果，其岩浆演化主要受早期结晶的辉石、斜长石及角闪石等矿物相的制约。
The Archean Pyroxene granites in the southern jilin province have different characteristies from the tonalitic-trondhjemitic-granodioritic gneisses (TTG) and anatectic potassium gran ites,and they do not belong to one part of the.Based on studing of geology, petrology and geochemistry it is indicated that the pyroxene granites were the results of the magma crystalline differentiation of crustal sources.and their magmatic evolution was controlled by the earlier crystalline pyroxenes,plagioclases and hornblendes.
