摘要

以过井地震剖面为基础,运用断层相关褶皱理论对昌吉背斜进行构造分析,利用平衡软件对构造进行复原,验证解释的合理性并展示构造运动学过程。过井地震剖面显示昌吉背斜由三个断层转折褶皱叠加形成前列式叠瓦状断层转折褶皱,部分位移量转换为反向逆冲断层,以复合型构造三角楔形式形成现今的昌吉背斜。
In southern margin of Junggar Basin,Changji anticline is located at eastern thrust fold belt.And it is a fault-related fold formed by the Beitianshan thrust nappe at foreland basin.In this study,based on seismic profile,a structural analysis is done for the anticline by means of the fault-related fold theory at first;and then,the anticline is reset by balance software.Seismic profile results show that Changji anticline is a forward imbricated fault-bend fold formed and imbricated by three fault-bend folds.And part displacement volume changed into back thrust fault and then formed the current Changji anticline in a way of compound structural triangle wedge.
