摘　　要：华北陆台北缘“基底”是由不同时代、不同特征的独立的构造单元组成的。它们原岩主体是以花岗质为主的深成侵入杂岩，层状岩石呈不同尺度的包体包镶在其中。这些构造单元是由构造原因。Basement of the North margin area of The North China platform includes separate tectonic units with different ages and characters. Their protolithes are mainly granitic plutons. Layered rocks occur as inclusions in varied sizes and are inlayed within the units. The units are collaged together by a serial tectonic events related spatially and temporally.
