Abstract
Melt migration experiments have been carried out to investigate the dependence of permeability on melt fraction and on orthopyroxene content for partly molten aggregates of olivine plus basalt and olivine-orthopyroxene plus basalt. For the experiments in which melt was initially present in both the source and the sink, the melt migration profiles could be fit equally well with a permeability proportional to the melt fraction to the first, second or third power. For the experiments in which the sink initially was melt-free, a best fit to the melt migration profiles could be obtained with a permeability that is linearly proportional to melt fraction. The melt migration profiles for samples in which the sink disc contained olivine plus 20 vol% orthopyroxene were esssentialy identical to those for samples in which the sink contained only olivine. -from Authors
