Melt Migration High-porosity zones, reactive transport channels: focusing the melt flow.
{"Image DocumentName": "Melt MigrationHigh-porosity zones, reactive transport channels: focusing the melt flow.", "Image ImageDescription": "This may arise due to reactive infiltration instability: porous flow of liquid breaks up into channels if it can dissolve the pyroxenes, leaving high melt fraction and olivine residue. The evidence for this process in nature is veins of dunite (pure olivine) in ophiolites: if melt flows through the dunite channels, this may explain the observation that MORB is not in equilibrium with abyssal peridotite (when you find dunites, these are in equilibrium with MORB). 30.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
