| 摘 要： | 准噶尔盆地中部现今呈南倾的大单斜构造背景，中1、3区块中生代曾发育一大型正向构造单元，分析认为属低幅背斜构造．中3、中1区块位于该背斜构造的南、北两翼，受背斜构造的影响较大，而中2、中4区块位于该背斜构造的东侧，受背斜构造的影响较小，中1、中3区块与中2、中4区块分属两个不同的构造单元．准中区块中生界侏罗、白垩系之间存在明显的角度不整合，应划分为两个不同的构造层．研究还发现，准中地区中、新生界具有明显的负反转构造特征． |
| 关 键 词： | 准中地区 构造单元 构造层 负反转构造 车-莫低幅背斜 |

| Abstract: | The central area of Junggar Basin shows as a big monoclinal structure in the direction of south today. During Cenozoic, a large positive structure had developed in block Zhong-1 and block Zhong-3 which was explained as a low amplitude anticlinal structure. Block Zhong-1 and block Zhong-3 are located on the south and north limb of the anticline respectively, and are deeply affected by the anticline. Block Zhong-2 and block Zhong-4 both located at the east of the anticline, and therefore are relatively slightly affected by it. Block Zhong-1 and Zhong-3 and block Zhong-2 and Zhong-4 belong to two different structural units respectively. There is an significant angular unconformity between Jurassic and Cretaceous in the central area of Junggar Basin, thus, the Jurassic and Cretaceous in this area should be two separate structural layers. It has been observed that, in the central area of Junggar Basin, there is a negative reversal structure in the Mesozoic and Cenozoic strata. |
