摘要
扎格罗斯褶皱冲断带是扎格罗斯碰撞造山带的前陆褶皱冲断带,也是波斯湾周缘前陆盆地的楔顶带,自北东到南西垂直于构造线方向可分为高扎格罗斯冲断带和扎格罗斯简单褶皱带;自北西到南东沿构造线方向可分为洛雷斯坦区(Lorestan)、迪兹富勒湾区(Dezful Embayment)和法尔斯区(Fars)。扎格罗斯褶皱冲断带的形成始于晚白垩世阿拉伯板块的洋壳向北俯冲到欧亚板块之下,褶皱冲断构造从北东部缝合带向南西方向伸展,并在上新世基本定型。本文选取了横切扎格罗斯褶皱冲断带的3条地质剖面和两条局部地震剖面进行构造变形分析。剖面分析显示研究区垂向上由一条大滑脱面将扎格罗斯褶皱冲断带剖面分为上、下两个构造层;褶皱冲断变形从北东到南西向由强变弱。研究区发育走滑、挤压和拉张3种构造变形,挤压构造变形占主导地位。挤压构造变形又包括滑脱褶皱、断展褶皱、断弯褶皱和双重构造等。
