Experimental Constraints on Melt Geometry and Migration in Partially Molten Peridotite

Kohlstedt [1992] provides a comprehensive synthesis of experimental constraints on the structure, rheology, and permeability of partially molten rocks. Riley and Kohlstedt [1991] presented experimental data that suggests that partially molten material in which the matrix is dominated by olivine will be very permeable even at very low melt fractions. Waff and Faul [1992] explored the effects of crystalline anisotropy on the distribution of melt in partially molten peridotite, and Daines and Kohlstedt [1994] showed that a transition from porous to channelized flow occurs due to melt/rock reaction during melt migration.
