摘要
文中对平顺岩体的岩相学、岩石化学及矿物学作了详细的研究。在橄榄角闪辉长岩中发现了辉石被角闪石交代的现象 ,在角闪闪长岩中亦存在自形程度很好的角闪石 ;对矿物的电子探针分析的结果 ,也说明既有原生岩浆成因的角闪石 。
The paper mainly studies on the petrographic, petrochemical characteristics and mineralogy of the Pingshun complexes, Shanxi Province On the basis of study of rock thin sections, the author has found that pyroxene is replaced by amphibole, yet amphibole with better crystal shape occurs in the Ampdiorite and OlAmpgabbro And through analysis of data of electronic probe, it shows that the Amphibole has two geneses, one is the result of primary magma, the other is the result of metasomatism through pyroxene under the condition of water bearing.
