玄武岩岩浆对火山的供应速度限制了其地幔内部的流动速度。由熔体和残渣层交替组成的层状源区的渗透率比渗流源大几个数量级。获得了夏威夷火山在10−4-10−2 cm~2范围内的源渗透率的相关供应率。结果在分层源的范围内，表明分层源在物理上是夏威夷羽状源的可行模型。
Abstract The supply rates of basaltic magma to volcanoes restrict the flow rates within their mantle sources. Layered source regions consisting of alternating layers of melt and residuum have permeabilities that are orders of magnitude larger than percolative sources. Relevant supply rates for Hawaiian volcanoes are obtained for source permeabilities within the range 10−4–10−2 cm2. The results are within the range for layered sources, suggesting that a layered source is a physically viable model for Hawaiian plume sources.
