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-Paleo-zoic,dividing it into six phases as follows.(1)The epicontinental accretion in the Neoproterozoic to Early Cambrian character-ized 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 archi-pelagic 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 archipe-lagic arc-basin systems in the Late Ordovician to Pridoli,as the erosion of the uplifted land masses;(5)The subduction of ar-chipelagic 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 Carbonifer-ous;(6)The oceanic-continental transition in the Late Carboniferous-Lopingian,characterized by the assembly of Jiamusi mas-sif,Songnen massif,and Khanka massif.Massifs of Northeast China completely collaged to a whole.
