| 摘 要： | 东秦岭-大别造山带是3 个板块沿两条缝合带俯冲碰撞而形成的近东西向不对称的反向多层次构造叠置的复合型造山带。在泥盆纪至三叠纪板块构造阶段中不同陆块间由于俯冲碰撞作用形成了多种挠曲类盆地。盆地时空演化充分体现了商丹古洋盆俯冲消减过程、北秦岭弧后区弧陆碰撞过程以及勉略古洋(海)盆斜向的、由东向西的碰撞造山过程。

| Abstract: | East Qinling-Dabie Shan is a composite orogenic belt developed by subduction and collision of three plates along two suture belts,which underwent a nearly E-W trending,unsymmetrical,double-directed,multi-leveled tectonic superposition.Several kinds of flexural basins were formed by the collision among continental blocks during the plate tectonic period from Devonian to Triassic.The space-time evolution of the basins fully indicates the processes of the subduction of Shang-Dan oceanic basin,the arc-continent collision in North Qinling,and the oblique collision from the east to the west in Mian-Lue oceanic basin. |
