9508004 Daines This pilot study involves an experimental project on melt migration in peridotites. It investigates the role of melt-rock reaction if the focusing of melt flow during melt migration in the upper mantle. The research involves a series of experiments in which basaltic melts undersaturated in pyroxene infiltrate synthetic peridotites composed of different proportions of olivine and pyroxene. The experiments will be analyzed through detailed characterization of microstructures, reaction fronts, and phase compositions, and by one-dimensional numerical simulations.

9508004 Daines 这项试点研究涉及橄榄岩中熔体迁移的实验项目。 它研究了上地幔中熔体运移过程中熔体流动聚焦时熔岩反应的作用。 该研究涉及一系列实验，其中辉石中不饱和的玄武岩熔体渗透由不同比例的橄榄石和辉石组成的合成橄榄岩。 实验将通过微观结构、反应前沿和相组成的详细表征以及一维数值模拟进行分析。
