This proposal requested support for research on the nature of the distribution of the liquid phase in partially molten materials representative of those occurring in the Earth's upper mantle. It is an experimental study of the wetting properties of basaltic melts of primitive composition as a function of temperature and pressure over ranges corresponding to accepted magma source regions. The wetting angles are primary determinants of fluid distribution and permeability for fluid flow. At the present time, wetting angle data are not available over much of the pressure-temperature range commonly attributed to magma source regions within the mantle. The information which will be provided by this research is needed for proper understanding of upper mantle magma segregation and transport processes operating in regions where primitive melt compositions are generated.

该提案要求支持对液相分布的性质的研究，这些液相的分布是代表地球上地幔中发生的那些材料的部分熔融材料。 这是对原始组成的玄武岩熔体的润湿特性的实验研究，这是与接受岩浆源区域相对应的温度和压力的函数。 润湿角是流体分布和流体流动性的主要决定因素。 目前，在通常归因于地幔内岩浆源区域的大部分压力温度范围内，润湿角度数据尚未获得。 需要这项研究提供的信息，以正确理解在产生原始熔体组成的区域运行的上地幔岩浆隔离和运输过程。
