Abstract
The supply rates of basaltic magma to volcanoes restrict the flow rate s within their mantle sources. Layered source regions consisting of al ternating layers of melt and residuum have permeabilities that are ord ers of magnitude larger than percolative sources. Relevant supply rate s for Hawaiian volcanoes are obtained for source permeabilities within the range 10(-4)-10(-2) cm(2) The results are within the range for la yered sources, suggesting that a layered source is a physically viable model for Hawaiian plume sources.
