0003561 Hallet该项目将利用喜马拉雅造山带的东部结来解决大陆碰撞的地球动力学中的关键问题:造山带和相关的高原是如何结束的,构造和表层过程如何相互作用以形成造山运动期间的地壳,以及变形如何在不同尺度上划分? 具体的假设是:1)流变学控制地形和岩石圈力学高原/indentor边缘; 2)侵蚀控制岩石圈动力学的地壳增厚和横向调节的程度相同,两者之间的反馈最终塑造造山带的演化;和3)有完全解耦的上地壳和下岩石圈变形的“同轴”区域。 要使用的方法包括跟踪的大小,速率和类型的质量通量通过喜马拉雅东部结的中部地区。 为此,首席调查员将使用地质年代学、地貌学、GPS、岩石学、地震学和构造技术,并通过三维建模进行全面整合。
英文摘要
0003561HalletThis project will use the eastern syntaxis of the Himalayan orogen to address key questions in the geodynamics of continental collisions: how do orogens and associated plateaus come to an end, how do tectonic and surficial processes interact to shape the crust during orogeny, and how is deformation partitioned at various scales? Specific hypotheses to be tested are: 1) rheology controls topography and lithospheric mechanics across plateau/indentor margin; 2) erosion controls lithospheric dynamics to the same extent as crustal thickening and lateral accommodation; feedbacks between the two ultimately shape the evolution of the orogen; and 3) there is complete decoupling between upper crustal and lower lithospheric deformation within the "syntaxial" region. The approach to be used involves tracking the magnitude, rates, and type of mass fluxes through the central region of the eastern Himalayan syntaxis. To do this, the Principal Investigators will use geochronologic, geomorphic, GPS, petrologic, seismic, and structural techniques, fully integrated by three-dimensional modeling.***
