项目摘要
Understanding of the evolution of alpine topography in many mountain chains represents an unresolved problem. A region like the northwestern Himalaya provides a particularly intriguing site for the study of evolving topography, because it is characterized by rapid Quaternary denudation, differential uplift, rivers showing some of the highest gradients and largest sediments loads in the world, a breadth of climatic regimes, active tectonicsm, and extreme topographic relief. In the absence of knowledge of rates of denudation, bedrock uplift, and surface uplift, reconstructions or models of topographic development are forced to rely on untested assumptions concerning the absolute magnitude and relative importance of each of these factors. In the northwestern Himalaya and Karakoram, it appears possible however, to combine digital elevation data sets with chronologic and geomorphic data on timing and magnitude of incision, erosion, and uplift in order to provide a calibrated perspective on topographic evolution of this dynamic region. The goals of this study are to define the timing and rates of incision and bedrock cooling in this part of the Himalayan orogen; to make volumetric approximations of regional denudation, reconstruct base- level changes along this part of the Indus River; and to reconstruct the interactions among tectonically generated localized uplift, regional uplift (tectonic or isostatic), and erosion and denudation. The approaches that will be used include: exposure-age dating of strath surfaces using cosmogenic nuclides; development of cooling ages histories using multi-mineral dating of vertical relief sections; reconstruction of river profiles based on temporal and geometric constraints; and analysis of slopes, altitudinal distributions, gradients, and volumes based on digital elevation data set for the NW Himalaya.
了解许多山脉中高山地形的演变是一个悬而未决的问题。喜马拉雅西北部这样的地区为研究不断演变的地形提供了一个特别有趣的地点,因为它的特点是第四纪快速剥蚀,差异隆起,河流显示出世界上一些最高的梯度和最大的沉积物负荷,广泛的气候制度,活跃的构造,以及极端的地形起伏。在缺乏剥蚀、基岩抬升和地表抬升速率的情况下,地形发育的重建或模型被迫依赖于关于这些因素的绝对大小和相对重要性的未经检验的假设。然而,在喜马拉雅和喀喇昆仑的西北部,似乎可以将数字高程数据集与关于切割、侵蚀和隆升的时间和强度的年代学和地貌数据结合起来,以便提供对该动态区域地形演化的校准透视。这项研究的目的是确定喜马拉雅造山带这一部分的切割和基岩冷却的时间和速率,对区域剥蚀进行体积近似,重建印度河这一部分的基准面变化;并重建构造引起的局部隆起、区域隆起(构造或均衡)和侵蚀剥蚀之间的相互作用。将使用的方法包括:使用宇宙成因核素对层状表面进行曝光年龄测定;使用垂直起伏段的多矿物测年方法开发冷却年龄历史;根据时间和几何约束重建河流剖面;以及基于西北喜马拉雅数字高程数据集的坡度、海拔分布、坡度和体积的分析。
