摘要： 准噶尔盆地在早中石炭世由于上地幔上隆,使由泥盆系和石炭系组成的过渡性基底岌生张裂,形成了堑叠式构造格局的雏形。应力释放后,在沉积物的重力作用下逐渐下沉,二叠纪是盆地发育的开始阶段,为分割性断陷岌育期,中生代继续下沉、统一,进入断坳发育期与坳陷岌育期。最后在中新世时萎缩上隆,形成了现代的准噶尔盆地。

Abstract: The embryo of graben-horst-like tectonic framework of Junggar Basin was originaly formed by an uplift of upper mantle during the time of the early-middle Carboniferous followed by a tension fault of the transitional basement for Devonian and Carboniferous systems. Its Permian, the stage of preliminary development of the basin, was down-faulted developing period. A period of fault/seg and depression occurred in Mesozoic with a continuous subsidence. Finally, after contractive uplift in Miocene ,Present Junggar Basin was formed in the end.
