根据地层、沉积岩相古地理及古地磁等资料综合分析，认为中国东北区古生代存在着额尔古纳—兴安、松嫩、佳木斯—兴凯等中、小板块群。其中，松嫩微板块和佳木斯—兴凯微板块于早古生代末沿牡丹江断裂拼合；额尔古纳—兴安微板块和松嫩—佳木斯—兴凯微板块于中晚泥盆世沿多宝山伊尔施一线拼合，至此形成统一的黑龙江板块。石炭二叠纪在黑龙江板块与华北板块之间为古亚洲洋的南支，中晚二叠世南北陆－陆对接，而陆内俯冲碰撞造山过程可能一直延续至早中侏罗世，缝合带从西拉木伦河东延至长春、延吉一线。而黑龙江板块与西伯利亚板块之间的蒙古—鄂霍茨克洋的最终闭合时限在晚侏罗世至早白垩世，缝合带东段为俄罗斯境内的南土库林格尔断裂。该带的最终拼合标志着统一的欧亚大陆的形成。
According to the comprehensive analysis of stratigraphy, sedimentary facies palaeogeography and palaeomagnetic data, it is concluded that the Paleozoic in northeastern China has middle and small plates of Ergun - Xing’an, Songnen, Jiamusi - Xingkai and so on. Among them, the Songnen Microtre plate and the Jiamusi-Xingkai Microfacies plate were combined at the end of the Early Paleozoic along the Mudanjiang fault; the Ergunar-Xingan Microfacies and the Songnen-Jiamusi-Xingkai Microfacies converged along the Duobaoshan Er Shi front line assembly, thus forming a unified Heilongjiang plate. The Carboniferous Permian is the southern branch of the ancient Asian Ocean between the Heilongjiang plate and the North China plate, and the mid-late Permian South-North continental-continental docking. However, the intracontinental subduction and collision orogeny may extend to the early Middle Jurassic and suture zone From Xilamulun East to Changchun, Yanji line. The closing time of the Mongolia-Okhotsk Ocean between the Heilongjiang plate and the Siberian plate lasts from the Late Jurassic to the Early Cretaceous. The eastern segment of the suture zone is the southern Turkulinagel fault in Russia. The final assembly of the band marks the formation of a unified Eurasian continent.
