摘要： 准噶尔盆地乌夏断裂带内以发育众多生长逆断层为特征,通过对断层生长指数、断层组合关系等的分析认为:断层的平面组合样式主要有平行式、雁列式、斜交式、正交式和帚状等5种类型;二叠纪时期断层以北东向为主,三叠纪-侏罗纪时期断层以近东西向为主,断层相互切割叠加,整体上呈弧形展布。断层的构造活动具有早期西部强于东部,晚期东部强于西部,以及从二叠纪到侏罗纪断层由西向东迁移、活动强度逐渐减弱的分区性和分段性特点。

Abstract: A large number of reverse growth faults occur in Wu-Xia fault belt of Junggar basin. This paper presents the analysis of the growth index of fault and the combination relations among faults and gives five types of lateral combinations of the faults like parallel, en echelon, oblique, orthogonal and brush ones. The study shows that in Permian, the faults mainly grew and distributed along NE direction, during Triassic and Jurassic, they distributed in crosscutting and superimposing and arc-like appearance along EW trend. The faults activities are characterized by subsection in space and segmentation in time, at the early time the faults activities were stronger in the west than in the east, however, at the late time things were opposite; from Permian to Jurassic the center of fault activities migrated from west to east, with gradually weakening of intensity.

Key words: Wuerhe-Xiazijie fault belt, fault, growth index, structural migration
