The Precambrian metamorphic basement of the eastern Hebei province (EHP) is located in the north margin of North China Craton (NCC).This metamorphic basement is composed of widespread metamorphic supracrustal rocks that were intruded by paleo-plutonic gneisses that are composed chiefly of dioritic-tonalitic- trondhje-mitic- granodioritic (DTTG) gneisses,orthopy-roxene (Opx)-bearing dioritic-tonalitic gneisses,and enderbitic- charnockitic gneisses.The Opx-bearing dioritic-tonalitic and the enderbitic- charnockitic gneisses are exposed in Taipingzhai- Yuhuzhai area of the EHP,and the both granitoid gneisses show gradual transition relationships on the field,while locally Opx- bearing tonalitic gneisses are rarely cross-cut by charnockitic veins (Fig.1A).
