| 摘 要： | 东北地块群主要有额尔古纳、兴华、松嫩、佳木斯和兴凯等地块,它们都不是从西伯利亚克拉通分裂出来的,而都具有独立的演化史.额尔古纳、兴华地块参与到西伯利亚板块东南大陆边缘古亚洲洋弧盆体系中,组成岛弧-山弧或弧后盆地的一部分;松嫩、佳木斯和兴凯地块分别为泛古洋和古太平洋作用区内亲西伯利亚和亲华北的地块,具有前白垩纪较复杂的演化史.在较详细讨论了东北地块群的构造演化的基础上,认为东北大地构造格架,除可以划分出西伯利亚板块和华北板块外,还应划分出滨太平洋松嫩-佳木斯联合地块、环太平洋兴凯地块、胶辽地块和那丹哈达地体.

| Abstract: | The Northeast China block group is composed of mainly Erguna,Xinghua,Songnen,Jiamusi and Khanka blocks.All of them have their own independent evolutionary history,but are not separated from the Siberia craton.The Erguna and Xinghua blocks joined the Palaeo-Asia Ocean arc-basin system in the southeastern continental margin of Siberia plate,to construct a part of island-arc,mountain-arc or back-arc basin.The Songnen,Jiamusi and Khanka blocks are close to Siberia plate and North China plate respectively,in the Panthalassic Ocean and Palaeo-Pacific Ocean affected area,showing complicated Pre-Cretaceous evolutionary history.Based on the detailed discussion about tectonic evolution of Northeast China block group,it is concluded that besides the Siberia and North China plates,there also should be the Songnen-Jiamusi united block in marginal-Pacific Ocean domain,the Khanka and Jiaoliao blocks and the Nadanhada terrain in circum-Pacific Ocean domain. |
