| 摘 要： | 东秦岭－大别造山带受不同块体间的拼合碰撞及其之后的陆内变形控制，在造山带边缘和内部形成了不同的盆山系统。造山带北缘响应北秦岭与华北板块的弧陆碰撞及其之后陆内变形作用，形成了后陆逆冲与弧后前陆盆地系统。造山带南缘三叠纪至白垩纪随着扬子板块与秦岭－大别微板块沿勉略缝合带自东向西的斜向俯冲和之后的陆内旋转挤压，在扬子北缘形成了前陆逆冲与周缘前陆盆地系统。自晚侏罗世末至白垩纪造山带挤压与伸展并存，伸展自核部向边缘发展，形成造山带伸展塌陷与近东西向裂谷盆地系统。大致在中始新世之后，受中国东部环太平洋构造带东西向伸展作用和深部构造作用控制，横跨造山带形成近南北向的裂谷盆地。

| Abstract: | Controlled by collision between continental blocks and intracontinental deformation, different basin-mountain systems were developed along East Qinling-Dabieshan orogenic belt. Response to arc-continent collision and its later intracontinental deformation between North Qinling and North China plates, the hinterland thrust and retro-arc foreland basin system was formed in the northern orogenic belt. Driven by obliquely subduction of the Yangtze plate under the Qinling plate and intracontinental deformation of the collided Yangtze plate associated with clockwise rotation of the Yangtze plate relative to the North China plate, the foreland thrust and peripheral foreland basin system was developed in the northern Yangzte. During latest Jurassic to Cretaceous, the shortening and extension events overlapped in the orogen, and it extended from the core to margins. A collapse structure and E-W trending rift basin system was formed. Since mid Eocene the main basin bounding faults were transverse to the orogen, which were controlled by E-W trending extension in East China circum Pacific belt and deep tectonism. |
