| 摘 要： | 中国东北盆山体系主要形成和发展于晚侏罗世晚期-新近纪，经历了晚侏罗世晚期-早白垩世小盆山（盆岭）和晚白垩世-新近纪大盆山（盆山）两个阶段的构造发展过程.盆岭阶段起始于东北高原向盆岭体系转换的张家口期，全盛于义县-九佛堂期，萎缩于盆岭向盆山体系构造转换的沙海-阜新期，结束于张老公屯期（东山期）.盆山阶段经历了晚白垩世早期大规模拗陷、晚白垩世晚期拗陷萎缩、古近纪大规模裂谷和新近纪后裂谷拗陷.认为太平洋板块对盆山体系形成和发展有巨大的影响，但无论是板块、地幔柱和超级地幔柱均不太可能形成如此规模，又具北北东向的中-新生代岩浆岩带和盆山体系，更可能是超级地幔热带、地幔柱和东亚多向板块汇聚背景下，西太平洋板块俯冲共同作用的结果.

| Abstract: | The basin-and-mountain system of Northeast China formed and developed mainly in the late stage of Late Jurassic-Neogene, involved two processes of tectonic development： the late Late Jurassic-Early Cretaceous small basin- and-mountain （basin-and-range） stage and the Late Cretaceous-Neogene big basin-and-mountain （basin-and-mountain） stage. The basin-and-range stage originated in the Zhangjiakou stage, when the Northeast Highland transformed into the basin-and-range system, developed in the Yixian-Jiufotang stage, withered in the Shahai-Fuxin stage, and finally ended in the Zhanglaogongtun stage （Dongshan stage）. The basin-and-mountain stage experienced the early Late Cretaceous huge depression, the late Late Cretaceous withering of depression, the Paleogene massive rift, and finally the Neogene post-rift sag. It seems that the Pacific plate remarkably effected the formation of the basin-and-mountain system. However, neither the plate, nor mantle plume and super plume are able to form such massive and NNE-striking Mesozoic-Cenozoic magmatic belt and basin-and-mountain system. It is more possibly the result of super mantle thermal zone and mantle plume action together with West Pacific plate subduction, under the background of East Asian multi-direction plate convergence. |
