[1] Through combination of surface wave and body wave constraints we derive a three-
dimensional (3-D) crustal S velocity model and Moho map for Iceland. It reveals a vast
plumbing system feeding mantle plume melt into upper crustal magma chambers where
crustal formation takes place. The method is based on the partitioned waveform
