摘　　要：阜平群变质岩主要由片岩、片麻岩、斜长角闪岩、变粒岩、浅粒岩、大理岩组成。通过薄片分析、岩相分析、岩石化学分析 ,揭示了阜平群变质岩的物质成分 ,结构特征和岩相特征 ,在岩石学研究的基础上 ,综合利用岩相标志 ,岩石化学参数变异图解和野外地质资料对阜平群变质岩原岩进行了研究。研究结果表明 ,阜平群变质岩的原岩为基性火山岩、陆原碎屑岩 。The metamorphite of the Fuping group composite of the schists,geneiss anorthositic amphibolite,epigranninular texture rock,light color graninular,rock and the marble through the silice,petrofacies and the solid-chemical analysis,the material composition,rock texture and the prtrofacic are revealed.Making full use of the facic mark,figurel of variation on the solid-chemical parameter and the geologycal data,the writer studied the photolyte of the Fuping group metamorphite.The rosult of studing show that the photolyte Fuping group metamorphite composite of basic volcanics,continentaldetrital rock,neatral and acidic pyroclast rock and the carbonate.
