摘　　要：对大兴安岭中南段花岗岩中的黑云母做了成分、物性、光性的测定,并系统研究了红外光谱、X射线衍射、差热等特征。结果发现,随成分变化,黑云母的物性、光性及各类谱学特点均呈规律性变化。同时根据黑云母的成分等得出了花岗岩的形成条件及其与成矿关系。结合各类谱学特点对花岗岩的演化规律也作了探讨。In this paper, compositional, physical and optical feature of biotites in granite are studied systematically, by means of infrared spectroscopy, X-ray analysis and differential thermal analysis. There suits exibihit a regular changing pattern in all those aspects. On the basis of composition of biotites, the forming condition of granite and its connection with minera-lization are carried out. The evolution pattern of granite is also disscus-sed.
