摘　　要：对内蒙古那干楚地区大民山组细碧角斑岩岩石特征、岩石化学特征、成因等3个方面进行研究分析,总结出细碧角斑岩经受了钠质交代变质作用和残余气热变质作用,经历了区域低温动力变质作用,成因是多阶段次生变质作用形成.Based on the study of lithology,lithochemistry and genesis of the spilite-keratophyre of Daminshan in Naganchu area,Inner Mongolia,it is concluded that the spilite-keratophyre was formed under sodic metasomatic metamorphism,residual pneumatothermal metamorphism and regional epithermal dynamic metamorphism.The genesis of the rock is multistage secondary metamorphism.
