Fault propagation patterns and interaction of neighbouring fault segments in compressional environments are not well understood. Importantly, the analysis of fault activity, slip rates, and kinematics has often resulted in contradictory assessments that call for a rigorous, quantitative assessment of these issues on different timescales. The North Tehran Thrust (NTT) and the sinsitral Mosha Fasham Fault (MFF) are neighbouring faults in the Alborz Mountains, northern Iran, which accommodate oblique shortening of the Arabia-Eurasia collision. The close proximity of both fault systems offers the unique opportunity to study the interaction of fault segments on different time and length scales and evaluate their possible linkage. In particular, geometry, kinematics, segmentation, and lateral propagation along both faults can be assessed. To decipher spatial and temporal fault behavior we propose geotectonic field mapping, supported by air photos, high-resolution satellite imagery, and digital elevation models. To develop a chronology of faulting and migration of deformation in the southern Alborz foreland, we will study clastic units with magnetostratigraphy, 40Ar/39Ar dating of tephra, and cosmogenic nuclide-dating (36Cl) of geomorphic surfaces. Our work will thus help to resolve discrepancies between measured geodetic and geologically derived deformation rates and contribute toward an assessment of the source of destructive earthquakes, and thus help to evaluate and mitigate seismic and related natural hazards.

压缩环境中相邻故障段的故障传播模式和相互作用尚不清楚。重要的是，对断层活动，滑移率和运动学的分析通常导致矛盾的评估，这些评估要求对不同时间标准的这些问题进行严格的定量评估。北德黑兰推力（NTT）和罪恶的Mosha Fasham断层（MFF）是伊朗北部Alborz山区的相邻断层，可容纳阿拉伯 - 欧洲裔碰撞的倾斜缩短。两个断层系统的紧密距离提供了独特的机会，可以在不同的时间和长度尺度上研究故障段的相互作用并评估其可能的链接。特别是，可以评估几何形状，运动学，分割和沿两个断层的横向传播。为了破译空间和时间断层行为，我们提出了地理场图映射，并由空气照片，高分辨率卫星图像和数字高程模型支持。为了开发南部Alborz前陆的断层和变形的迁移的年表，我们将研究具有磁层学，Tephra的40AR/39AR日期的碎屑单元，以及地质形态表面的宇宙基因核素约会（36Cl）。因此，我们的工作将有助于解决测量的大地测量和地质变形率之间的差异，并有助于评估破坏性地震的来源，从而有助于评估和减轻地震和相关的自然危害。
