欧亚北极东部地区资源丰富,但由于区域地质构造复杂,勘探程度低,盆地分布及其发育的构造背景仍存在很大的争议.在大量收集整理区域地质文献的基础上编制了该区构造简图,并对区域地质构造及其演化进行梳理.该区主要构造单元包括:上扬斯克-科雷马造山带、北极阿拉斯加-楚科塔微板块、科雷马-奥莫隆复合超地体、南阿纽伊缝合带等.早侏罗世至早白垩世,随着美亚海盆的张开,北极阿拉斯加-楚科塔微板块裂离加拿大北部陆缘,并随着Anui-Anvil洋的关闭,与科雷马-奥莫隆超地体及亚洲大陆北缘碰撞,形成新西伯利亚-楚科奇造山带-布鲁克斯造山带及南阿纽伊缝合带.上扬斯克-科雷马造山带是晚侏罗世-早白垩世科雷马-奥莫隆超地体与西伯利亚克拉通边缘的碰撞结果.
However, due to the complex regional geological structure, low exploration level, basin distribution and tectonic setting of its development, there are still many controversies in the eastern Eurasian Arctic. Based on a large number of geological literature collected and collated, The main tectonic units in this area include the Upper-Yankek-Correma orogen, the Arctic Alaska-Chukotka microplate, the Korma-Omoron complex super-terrane, South Anwei suture, etc. From Early Jurassic to Early Cretaceous, with the opening of the Mayer Basin, Arctic-Chukotar microplates in the Arctic split off the northern margin of Canada, and with the closure of the Anui-Anvil Ocean, Collided with the Koremao-Omoron supercontinent and the northern margin of the Asian continent to form the Novosibirsk-Chukotka or-Brooks orogenic belt of the South Anuiyu. The Janusk-Korima orogen was a late-j Collision between the Early Cretaceous Koleimao - Omoron supercontinent and the Siberian craton ’s edge.
