Reconciling geochemical and geophysical observations of magma supply and melt distribution at the 9N overlapping spreading center, East Pacific Rise

Wanless, VD; Perfit, MR; Klein, EM; White, S; Ridley, WI (Geochemistry, Geophysics, Geosystems, 2012-11-01)

Early studies of mid-ocean ridge discontinuities, such as transform faults and overlapping spreading centers, suggested a lower magma supply compared to ridge segment centers. This is reflected in bathymetrically deeper ...

Volatile abundances and oxygen isotopes in basaltic to dacitic lavas on mid-ocean ridges: The role of assimilation at spreading centers

Wanless, VD; Perfit, MR; Ridley, WI; Wallace, PJ; Grimes, CB; Klein, EM (Chemical Geology, 2011-08-07)

Most geochemical variability in MOR basalts is consistent with low- to moderate-pressure fractional crystallization of various mantle-derived parental melts. However, our geochemical data from MOR high-silica glasses, including ...
