摘    要:新的研究证实 ,华北板块北缘残存一条元古宙构造岩片堆集带 ,包括古元古代、中元古代、新元古代等多期构造岩片。并相伴有 180 0Ma±、140 0Ma±、10 0 0Ma±、6 5 0Ma±的花岗岩类的侵入活动和构造变质成矿等热事件的年代记录 ,并在华北板块北部金镶边带中保存了相一致的信息 ,揭示了它们是陆缘多期拼贴造山的产物。这为超大陆旋回 ,特别是元古宙两次超大陆的聚合与裂解及其构造演化过程的研究提供了良好的野外实验园地 ,并为元古宙、特别是古元古代大陆的增生及Rodinia超大陆在北半球的存在或构造响应提出新的课题。

关 键 词:华北板块  北缘活动带  元古宙  构造岩片  超大陆拼合事件  花岗岩

Abstract:Up-to-date studying proved that there is a pile up belt of Proterozoic tectonic slices along the northern margin of North China Plate. It is consist of early Proterozoic, middle Proterozoic and late Proterozoic tectonic slices etc. It was accompanied by intrusive activity of granites, tectono-metamorphic heat events and mineralization of 1 800 Ma,1 400 Ma,1 000 Ma and 650 Ma ages. Meanwhile, the same imformation was preserved well in the edge belt with gold in the northern margin of North China Plate. It brings to light that they were result of piecing together by multicycle orogeny in the northern margin of North China Plate. It would provide a better field laboratory for the study of cycle of super continent, especially for twice converging and splitting of super continent in Proterozoic Eon and its process of tectonic evolution. It will provide also a new scientific problem for the study of Proterozoic,especially for the multiplication of early Proterozoic continent and the exsistence of Rodinia super continent or its tectonic response in northern hemisphere area.
Keywords:North China Plate  active belt of north margin  Proterozoic Eon  tectonic slices
