东北亚地区的北东向构造在晚中生代—新生代经历了形成、发展和壮大3个阶段。晚侏罗世它作为新生构造出现但表现形式和地球动力学背景因地而异:蒙古东部受制于蒙古—鄂霍次克造山带(北东向的宗莫德段)的坍塌而出现一组北东向的伸展盆地;大兴安岭(含塔木察格)地区发生陆内的热造山作用,是对东亚大陆边缘区北东向郯庐断裂带和长乐—南澳断裂带形成并沿之发生移置地体斜向汇聚—剪切造山作用的响应。早白垩世在蒙古东部—中国北部出现一组北东向张扭盆地且有共同的成盆动力学背景。晚白垩世早—中期大兴安岭和海拉尔—塔木察格地区隆起,出现“两坳夹一隆”的格局。随新近纪陆内地区进一步伸展,蒙古东部和中国北部的白垩纪盆地均被更新世的坳陷上叠且面积扩大;蒙古中北部地区有北东向正断层形成并控制了地堑发育和玄武岩喷发,表征了北东向构造向西扩大。
The NE direction in Northeast Asia is formed in the late Mesozoic-Cenozoic experienced three stages of formation, development and expansion. Late Jurassic occurs as a newborn structure but its manifestations and geodynamic background vary from place to place: a group occurs in eastern Mongolia subject to the collapse of the Mongolian-Okhotsk orogenic belt (the northeastern Zomoph) North-east stretching basin. The intracontinental thermal orogeny occurred in the Greater Khingan Range (including the Ta Mucha) area. It is the result of the intracontinental thermal orogeny formed along the northeastern Tan-Lu fault zone and Changle-Nan’ao fault zone in the marginal zone of East Asia continent Body oblique convergence - the response of shear orogeny. Early Cretaceous a series of NE-trending torsional basins in the eastern part of Mongolia-northern China with a common basin-forming kinetic background. Late Cretaceous Daxinganling early and mid-Hailar - Taqianguag area uplift, there “two Ao Jiaolian a” pattern. With the further extension of Neocene inland area, Cretaceous basins in eastern Mongolia and northern China were superimposed by pleistocene depressions and expanded in area. There are northeast normal faults in central and northern Mongolia and control of graben development and basalts Eruptions, which characterize the north-easterly structure expanding westward.
