The Zagros Belt has examples of strike-slip faults affected by precursor Hormuz Salt bodies. We attempted to examine the role of salt walls in localizing the strike-slip faults using field observations, seismic profiles and understandings from the sandbox modeling. Setting and performance of the pre-Hormuz features in connection to the salt tectonics are major questions. The inherited topography below the salt is an important parameter which controlled the structuration of the basin. The antecedent troughs provided accommodation for the thick Hormuz Salt. Differential loading above the salt helped generation of salt-related structures. The salt-walls caused formation of elongated highs. These highs were re-shaped in form of strike-slip faults during the Zagros Orogeny. The intersection of the salt walls and the Zagros-induced deformation fronts are location of potential diapirs needless of bending points along the tear faults. In contrast, the underlying deep-seated basement faults are hardly believed to be strike-slip.

研究霍尔木兹盐体在扎格罗斯褶皱和逆冲带 Fars 带走滑断层起始和演化中的作用:来自地震数据和沙箱建模的见解

扎格罗斯带有受前体霍尔木兹盐体影响的走滑断层的例子。我们试图通过现场观测、地震剖面和沙箱模型的理解来研究盐壁在定位走滑断层中的作用。与盐构造相关的前霍尔木兹特征的设置和性能是主要问题。盐下继承的地形是控制盆地结构的重要参数。先行槽为厚厚的霍尔木兹盐提供了住宿条件。盐上方的差异加载有助于生成与盐相关的结构。盐壁导致形成拉长的高点。在扎格罗斯造山运动期间,这些高点以走滑断层的形式重新塑造。盐壁和扎格罗斯诱发变形前沿的交叉点是潜在底辟的位置,不需要沿着撕裂断层的弯曲点。相比之下,下伏的深部基底断层很难被认为是走滑。
