华北克拉通古元古代区域构造至少可以划分出三大构造单元:(1)陆内裂谷带(2.30~2.60Ga);(2)陆缘造山带(2.30~2.60Ga);(3)再造的太古代克拉通区(麻粒岩相带)(大于2.50Ga).太古代末—古元古代重要的区域性构造-热事件序列依次为:(1)克拉通中部不同地壳层次伸展及裂谷盆地的发育;(2)克拉通北缘构造活动、增生及陆壳基底再造;(3)与大陆裂谷盆地闭合过程相联系的板内造山-前陆盆地发育.板块构造模式可以很好地解释上述构造作用类型.
The Paleoproterozoic regional structure of North China Craton can be divided into at least three tectonic units: (1) intracontinental rift zone (2.30 ~ 2.60Ga); (2) continental margin orogeny (2.30 ~ 2.60Ga ); (3) Reconstructed Archean cratonic zone (granulite facies belt) (greater than 2.50 Ga). Late Archean-Important Palaeozoic regional tectono-thermal event sequences were as follows: (1) the extension of different crustal gradations and rift basins in the central craton; (2) the tectonic activities in the northern margin of the craton, Rebuilding; (3) intraplate orogeny-foreland basin associated with the closing process of the rift basins in the continent. Plate tectonic mode can well explain the type of tectonic action mentioned above.
