项目摘要
It is well known that when tectonic plates containing continents collide, mountains are formed. What is surprising is that when the mountains are formed the lower part of the thickened continental crust (at more than 30 km depth) may flow like a very slow moving fluid. However this flow may not be progress steadily, because the strength of the flowing crust may change. Such changes in strength potentially cause effects that may extend to the surface topography. This project is aimed at investigating by field studies, lab analyses and computer modeling how the strength of the lower crust changes during flow. Understanding the details of this lower crustal flow is important for understanding the long-term (millions of years) behavior of large mountain belts such as the Himalaya that have an important role in maintenance of the Earth's climatic environment.
众所周知,当包含大陆的构造板块碰撞时,山脉就形成了。令人惊讶的是,当山脉形成时,加厚的大陆地壳的下部(深度超过30公里)可能会像一种非常缓慢的流动流体一样流动。然而,这种流动可能不会稳步进行,因为流动地壳的强度可能会发生变化。这种强度变化可能会导致影响,可能会延伸到表面形貌。该项目旨在通过野外研究、实验室分析和计算机模拟来调查流动期间下地壳的强度如何变化。了解这种下地壳流动的细节对于了解喜马拉雅山等大型山脉的长期(数百万年)行为非常重要,这些山脉在维持地球气候环境方面发挥着重要作用。
