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 ,中酸性火山碎屑岩和碳酸盐岩 The Fuping Group metamorphic rocks are mainly composed of schist, gneiss, amphibolite, granulite, light-grained rock and marble. Based on the petrological study, the lithofacies, lithofacies markers, petrochemical parameter variation diagrams and the field are analyzed comprehensively by means of lamellar analysis, lithofacies analysis and petrochemical analysis, and the physical composition, structural characteristics and lithofacies characteristics of metamorphic rocks in Fuping group are revealed. Geological data on the Fuping group metamorphic rock protoliths. The results show that the original rocks of Fuping group metamorphic rocks are basic volcanic rocks, Luyuan clastic rocks, intermediate-acid pyroclastic rocks and carbonate rocks
