The tectonic evolution of southern Junggar basin can be classified into seven stages: stage of intracontinental rift from middle Periman to late Late Carboniferous; stage of weak extension and peneplane from late Permian to early Triassic; stable depression stage in middle-late Triassic; maximal basin formation phase in the setting of weak extension in early-middle Jurassic; inactive depressed basin formation phase in thrust setting in middle-late Jurassic; stable depression stage in Cretaceous and Eogene; foreland depressed basin formation phase in thrust setting in Neocene and Quaternary.

准噶尔盆地南缘晚石炭世以来盆地构造演化可划分为七个演化阶段：晚石炭世—中二叠世陆内裂谷作用阶段；晚二叠世到早三叠世处于弱伸展-稳定坳陷作用阶段；中、晚三叠世准平原化作用阶段；早、中侏罗世为弱伸展背景下广盆形成阶段；中、晚侏罗世冲断背景下的坳陷盆地形成阶段；白垩纪到古近纪弱伸展背景下的稳定坳陷盆地形成阶段；新近纪—第四纪为冲断背景下的前陆坳陷盆地形成阶段。
