中文摘要
拟议工作的目的是了解如何利用在地球表面喷发的熔岩的化学变化来更好地洞察地球深处发生的物理过程。我们将使用计算熔体和地幔耦合流动的动态计算机模型来探索可观测的地球化学对地幔过程变化的敏感性。同时,我们将编制参考地球化学和地球物理数据集,对模型进行比较和检验。通过理论和观测的结合,这项工作可能会给地球深处的过程带来比经典地球动力学或地球化学单独的更强的约束。
英文摘要
The purpose of the proposed work is to understand how to use the chemical variation of lavas erupted at the Earth's surface to provide better insight into the physical processes occuring in the deep Earth. We will use dynamic computer models that calculate the coupled flow of melt and mantle to explore the sensitivity of observable geochemistry to changes in mantle processes. At the same time we will compile reference geochemical and geophysical data-sets to compare with and test the models. Through a combination of theory and observation, this work may give much stronger constraints on deep Earth processes than either classical geodynamics or geochemistry alone.
