中亚造山带记录了三个拼贴系统的增生和会聚，最终旋转成两个主要的造山带。蒙古拼贴系统是一个长的，南北向的复合带，旋转到目前的方向时，蒙古鄂霍次克造山带形成。哈萨克斯坦拼贴系统的组成部分被焊接在一起，形成一个长的，单一的复合弧，弯曲形成哈萨克斯坦的造山带。北山造山带将塔里木和华北两大板块缝合在一起，并以北方的索隆克缝合带的形成而终止。这三个拼贴体系的所有组分都是由新元古代生成的，并在二叠纪-三叠纪合并。中亚造山带的演化经历了多期拼合过程中多个造山组分的多次汇聚和增生，并经历了两期造山旋转。
The Central Asian Orogenic Belt records the accretion and convergence of three collage systems that were finally rotated into two major oroclines. The Mongolia collage system was a long, N–S-oriented composite ribbon that was rotated to its current orientation when the Mongol-Okhotsk orocline was formed. The components of the Kazakhstan collage system were welded together into a long, single composite arc that was bent to form the Kazakhstan orocline. The cratons of Tarim and North China were united and sutured by the Beishan orogen, which terminated with formation of the Solonker suture in northern China. All components of the three collage systems were generated by the Neoproterozoic and were amalgamated in the Permo-Triassic. The Central Asian Orogenic Belt evolved by multiple convergence and accretion of many orogenic components during multiple phases of amalgamation, followed by two phases of orocline rotation.
