对准噶尔盆地露头区以及钻井、物探资料进行了分析 ,同时对全盆地二叠系进行了地层划分和对比。结合对准噶尔盆地周缘大地构造环境及基底特征的分析结果 ,将准噶尔晚石炭世—二叠纪盆地定义为前陆盆地 ,其中发育 3个前陆盆地系统 :①西缘前陆盆地系统 ,该系统早期为近南北向延伸 ,从玛湖一直延伸到古车排子山前 ,后期分成南北两部分 ,北部称为西北缘前陆盆地 ,而南部被北天山前陆盆地系统所叠加 ;②克拉美丽前陆盆地系统 ;③北天山前陆盆地系统。各盆地系统的范围、发育时间和程度不同 ,前两个前陆盆地系统发育时间稍早 ,而后者盆地范围较前两者大。盆地中的所有构造特征都是这三大前陆盆地系统各构造组成要素叠加复合的结果。
The outcrop area of Junggar basin and drilling and geophysical data were analyzed. At the same time, the stratigraphic division and contrast of the Permian in the whole basin were carried out. Based on the analysis of the geotectonic environment and basement characteristics of the Junggar Basin, the Late Carboniferous-Permian basin in Junggar Basin was defined as a foreland basin, in which three foreland basin systems were developed: ① the foreland basin system in the western margin, It extends from Mahu to the Paopishan front of the ancient car and is divided into two parts in the north and the south. The northern part is called the foreland basin in the northwestern margin and the southern part is superimposed by the system in the northern Tianshan foreland basin. Foreland basin system; ③ Northern Tianshan foreland basin system. The scope, development time and extent of each basin system are different. The first two foreland basins developed earlier and the latter had larger extents than the former two. All tectonic features in the basin are the result of superposition and combination of the structural elements of the three foreland basin systems.
