Isotope evidence of a mantle convection boundary at the Australian-Antarctic Discordance
(Nature, 1988-12-01)Basalts from the Southeast Indian Ridge south of Australia form two geographically and isotopically distinct groups that show affinities with either Indian Ocean or Pacific/Atlantic Ocean isotope compositions. The data raise ... -
Mixing of basalt magmas
(Nature, 1989-12-01) -
Ocean-ridge basalt compositions correlated with palaeobathymetry
(Nature, 1990-12-01)KLEIN and Langmuir1 investigated the relationships between the chemistry and water depth of eruption of zero-age mid-ocean-ridge basalts around the world. They showed that the regionally averaged values of the major-element ... -
Petrological systematics of mid-ocean ridge basalts: Constraints on melt generation beneath ocean ridges
(Mantle Flow and Melt Generation at Mid-Ocean RidgesGeophys. Monogr. Ser., 1992)Mid-ocean ridge basalts (MORB) are a consequence of pressure-release melting beneath ocean ridges, and contain much information concerning melt formation, melt migration and heterogeneity within the upper mantle. MORB major ... -
Reconciling geochemical and geophysical observations of magma supply and melt distribution at the 9N overlapping spreading center, East Pacific Rise
(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 ... -
Tectonic and magmatic segmentation of the Global Ocean Ridge System: A synthesis of observations
(2016-01-01)© 2016 The Author(s).Mid-ocean ridges display tectonic segmentation defined by discontinuities of the axial zone, and geophysical and geochemical observations suggest segmentation of the underlying magmatic plumbing system. ... -
Volatile abundances and oxygen isotopes in basaltic to dacitic lavas on mid-ocean ridges: The role of assimilation at spreading centers
(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 ...
