Late Pleistocene‐Holocene Slip Rates in the Northwestern Zagros Mountains (Kurdistan Region of Iraq) Derived From Luminescence Dating of River Terraces and Structural Modeling

A significant amount of the ongoing shortening between Eurasian and Arabian plates is accommodated within Zagros Fold-Thrust Belt. However, spatial temporal distribution active belt, especially in its NW part, not yet well constrained. We determined depositional ages uplifted river terraces crossing belt along Greater Zab River using luminescence dating. Kinematic modeling fault-related fold was then used to calculate long-term slip rates during Late Pleistocene Holocene. Our results provide new insight into faulting folding area. The Mountain Front Fault accommodates about 1.46 ± 0.60 mm a−1 slip, while a more external basement fault further SW less than 0.41 0.16 a−1. Horizontal related detachment two anticlines Foothills are 0.40 0.10 1.24 0.36 Basement thrusting thickening crust restricted NE part belt. This also reflected regional topography terraces.
