Mid‐Ocean Ridge (MOR) Ash Dispersal on Axial Seamount, Juan de Fuca Ridge

Abstract Rare eruption of primitive normal mid‐ocean ridge basalt (N‐MORB) magma (∼9.5 wt% MgO) on the summit of Axial Seamount generated abundant ash that was dispersed for several km. The unique geochemical signature of this ash deposit is distinct from otherwise typical MORB with more evolved com...
