9909453威尼克大多数主要山脉都记录了岩体相对于地表的向上运动,但由于补偿侵蚀,很难确定是否形成了显著的地形高程,以及它在构造旋回中发生的时间。该项目将利用一种相对较新的方法来估计爱达荷州萨蒙河-克利尔沃特山脉的地形抬升年龄,该地区类似于更南边的科迪勒拉的内华达山脉,那里的古抬升已被证明始于白垩纪。结果将有助于确定科迪勒拉高程发展的空间格局,并将为该方法提供进一步的测试或验证。
英文摘要
9909453WernickeThe upward motion of rock masses relative to the earth's surface has been documented for most major mountain belts, but because of compensating erosion, it is difficult to determine if significant topographic elevation developed and when in the tectonic cycle it occurred. This project will utilize a relatively new method for estimating the age of topographic uplift in the Salmon River-Clearwater Mountains of Idaho, an area analogous to the Sierra Nevada further south in the cordillera, where paleoelevation has been shown to start during the Cretaceous. Results will help determine the spatial pattern of elevation development in the Cordillera and will provide a further test or validation of the method.
