New Nature paper: Pathway from subducting slab to surface for melt and fluids beneath Mount Rainier.

Professor Stéphane Rondenay, Department of Earth Science, is a co-author on this Nature paper. The study aims at obtaining an image of the complete pathway of the fluid–melt phase from the subducted oceanic crust to the surface.

This study combines new magnetotelluric data with seismic records collected from the same dense west–east transect across central Washington State to obtain an image of the complete pathway of the fluid–melt phase from the subducted oceanic crust to the surface.The authors identify and connect fluid release at or near the top of the subducting slab, migration of fluids into the overlying mantle wedge, melting in the wedge,and finally transport of the melt/fluid phase to a reservoir in the crust beneath the active volcano Mount Rainier.
