中文摘要
Kohlstedt 9526925对上地幔流变学的三个核心问题进行了实验研究:(1)粘度与水浓度的关系;(2)蠕变行为与矿物学的关系;(3)蠕变速率与压力的关系。拟议的实验旨在对水、矿物学和压力对地幔岩石流动行为的作用有一个基本的物理理解。这项研究的一个重要目标是确定塑性流动的定量本构方程,以便将实验室结果可靠地外推到上地幔环境。
英文摘要
Kohlstedt 9526925 An experimental investigation of three central issues in upper mantle rheology is proposed: (I) the dependence of viscosity on water concentration, (ii) the dependence of creep behavior on mineralogy and (iii) the dependence of creep rate on pressure. The proposed experiments are designed to gain a basic physical understanding of the roles of water, mineralogy and pressure on the flow behavior of mantle rocks. An important goal of this research is to determine quantitative constitutive equations for plastic flow that permit reliable extrapolation of laboratory results to upper mantle environments.
