科尔施泰特9526925 本文提出了上地幔流变学中三个中心问题的实验研究:(1)粘度对水浓度的依赖性,(2)蠕变行为对矿物学的依赖性和(3)蠕变速率对压力的依赖性。 拟议的实验旨在获得水,矿物学和压力对地幔岩石流动行为的作用的基本物理理解。 这项研究的一个重要目标是确定定量塑性流动的本构方程,允许可靠的实验室结果外推到上地幔环境。
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.
