| 摘 要： | 在系统分析兴蒙造山系新元古代-古生代24个沉积盆地类型、沉积建造、生物地层与年代地层等特征的基础上，划分了6个沉积大地构造演化阶段并对其进行讨论:(1)新元古代-寒武纪早期陆缘增生阶段:额尔古纳地块向南增生并与兴安地块拼贴，形成环宇-新林蛇绿岩拼合带；(2)寒武纪纽芬兰世-第二世陆缘稳定沉积阶段:各地块边缘发育相对稳定的碎屑岩-碳酸盐岩沉积，佳木斯地块受晚泛非造山作用影响；(3)早-中奥陶世多岛弧盆系形成阶段:多宝山地区弧盆系发育，其他地块边缘均有不同强度陆间洋壳俯冲作用；(4)晚奥陶世-志留纪普里道利世多岛弧盆系发展阶段:各地块隆升遭受剥蚀；(5)早泥盆世-早石炭世多岛弧盆系消减阶段:早石炭世晚期额尔古纳-兴安地块与松嫩地块拼贴，佳木斯西缘由被动陆缘转为活动陆缘；(6)晚石炭世-二叠纪乐平世拼合后洋-陆转化阶段:从早石炭世晚期开始至二叠纪末，佳木斯地块分别与松嫩地块、兴凯地块拼贴，至此东北各地块拼贴完成.

Neoproterozoic-Paleozoic Sedimentary Basins Evolution of Xing-Meng Orogenic Belt |
| |
| Abstract: | Based on comprehensive analysis of the type, sedimentary formation, biostratigraphy and chronostratigraphy for 24 main sedimentary basins, we study the evolution of sedimentary basins of Xing-Meng orogenic belt in the Neoproterozoic-Paleozoic, dividing it into six phases as follows. (1) The epicontinental accretion in the Neoproterozoic to Early Cambrian characterized by the assembly of Ergun and Xing'an blocks, as Huanyu-Xinlin ophiolite accreted to margin of southern Ergun blocks; (2) The stable epicontinental sediment in the Terreneuvian-Serises 2, with the feature of a relatively stable clastic-calciclastic sediment around the blocks while Jiamusi massif affected by Late Pan-African metamorphic event; (3) The formation of archipelagic arc-basin systems in the Early and Middle Ordovician, marked by the distribution of arc-basin in the margin of Duobaoshan and the different levels oceanic crust subduction effect among other land masses; (4) The development of archipelagic arc-basin systems in the Late Ordovician to Pridoli, as the erosion of the uplifted land masses; (5) The subduction of archipelagic arc-basin systems in the Early Devonian to Early Carboniferous, characterized by the collage of Ergun-Xing'an and Songnen blocks and the transformation of western margin of Jiamusi massif from passive to active in the late Early Carboniferous; (6) The oceanic-continental transition in the Late Carboniferous-Lopingian, characterized by the assembly of Jiamusi massif, Songnen massif, and Khanka massif. Massifs of Northeast China completely collaged to a whole. |
