摘要
应用活动观点划分麻粒岩相、高角闪岩相和低角闪岩相３个地层区。将全省太古宙地层划分为安子岭片麻岩、变质火山－沉积岩系、面型英云闪长质─花岗闪长质片麻岩、ＴＴＧ型高位侵入岩套和花岗岩套等５大套岩石地层，并按基本岩石地层单位建立地层序列表。对太古宙─早元古代地壳运动和主要构造事件，多期变质作用等进行论述，划分出三期褶皱、三期韧性剪切带。提出区域性递增变质带新概念，论证了安子岭片麻岩是最古老的陆壳。
Metamorphic complex in Hebei province has been divided into three metamorphic areas(granulite facies.high amphibolite facies and low amphibolite facies)and five rockstratigraphic units (Anzilieng gneisses,melavolcanite-Sedimentary rock series,planar tonalitic-granodioritic gneisses,TTG high emplacement rock suite and granute rock suite).The paper discuss Archaean-proterozoic crustal movement,and divide into three folds and three ductile shear zones.A new conception of Regional Progressive Metamorphism Zone has been advanced.Through the research,We think that Anzilieng gneisses are the oldest crustal rocks in Hebei Province.
