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.

这项实验研究的目的是了解部分熔融岩石中的变形与熔体迁移之间的关系，并找出熔体如何实际移动，这是温度，压力，岩性压力，岩浆压力，应变率和时间的变化函数。在变化的压力条件下，具有一个或两个固体相的条件下，将在静水熔体提取实验中进行部分熔融岩石，并具有可变量和粘度的熔体，这将导致不同实验中的渗透率显着差异。三轴变形实验也将在可变温度，熔体渗透率和应变速率下进行。在实验之前和之后，将仔细检查样品以评估物理特性。渗透率将直接在某些实验中进行测量。结果将根据先前的实验和理论考虑来评估。
