The Salt Range in Pakistan exposes Precambrian to Pleistocene strata outcropping along the Salt Range Thrust (SRT). To better understand the in‐situ Cambrian and Pliocene tectonic evolution of the Pakistan Subhimalaya, we have conducted low‐temperature thermochronological analysis using apatite (U‐Th‐Sm)/He and fission track dating. We combine cooling ages from different samples located along the thrust front of the SRT into a thermal model that shows two major cooling events associated with rifting and regional erosion in the Late Palaeozoic and SRT activity since the Pliocene. Our results suggest that the SRT maintained a long‐term average shortening rate of ~5–6 mm/yr and a high exhumation rate above the SRT ramp since ~4 Ma.

低温热年代学约束的盐范围古生代和上新世构造演化

巴基斯坦的盐岩带使前寒武纪沿盐岩冲断带（SRT）露头到更新世地层露头。为了更好地了解巴基斯坦Subhimalaya的寒武纪和上新世构造演化，我们使用磷灰石（U-Th-Sm）/ He和裂变径迹测年进行了低温热年代学分析。我们将沿SRT逆冲锋面的不同样品的冷却年龄组合到一个热模型中，该模型显示了自上新世以来古生代晚期和SRT活动发生的与裂谷和区域侵蚀有关的两个主要冷却事件。我们的结果表明，自〜4 Ma以来，SRT的长期平均缩短速率为〜5–6 mm / yr，高于SRT斜坡的高尸体挖掘速率。
