The goal of this experimental study is to understand the relation between deformation and melt migration in partially molten rocks and to find out how melt actually moves as a function of varying temperature, stress, lithostatic pressure, magma pressure, strain rate, and time. Partly molten rocks will be tested in hydrostatic melt extraction experiments under conditions of varying pressure, with one or two solid phases, and with melt of variable amount and viscosity, which will result in significant differences in permeability in different experiments. Triaxial deformation experiments will also be carried out at variable temperatures, melt percents, and strain rates. Samples will be carefully examined before and after the experiments to evaluate physical properties. Permeabilities will be measured directly in some of the experiments. Results will be evaluated in light of previous experiments and theoretical considerations.

本实验研究的目的是了解变形和熔体迁移在部分熔融岩石之间的关系，并找出熔体实际上如何移动作为变化的温度，应力，岩石静压力，岩浆压力，应变率和时间的函数。部分熔融的岩石将在不同压力条件下进行流体静力学熔体提取实验，具有一个或两个固相，并且具有可变量和粘度的熔体，这将导致不同实验中渗透率的显著差异。三轴变形实验也将在不同的温度，熔体粘度和应变速率下进行。在实验前后将仔细检查样品，以评估物理性能。在某些实验中将直接测量渗透率。结果将根据以前的实验和理论考虑进行评估。
