4.13 - Composition of the Oceanic Crust
(Treatise on Geochemistry (Second Edition), 2014) -
Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness.
(Journal of Geophysical Research, 1987)Thermal modeling independently predicts the observed relationships among basalt chemistry, ridge depth, and crustal thickness resulting from temperature variations in the mantle. Beneath the shallowest and deepest ridge ... -
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 ... -
Lava geochemistry as a probe into crustal formation at the East Pacific Rise
(Oceanography, 2012-03-01) -
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 ... -
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 ... -
Seafloor photo-geology and sonar terrain modeling at the 9°N overlapping spreading center, East Pacific Rise
(Geochemistry, Geophysics, Geosystems, 2013-12-01)A fundamental goal in the study of mid-ocean ridges is to understand the relationship between the distribution of melt at depth and seafloor features. Building on geophysical information on subsurface melt at the 9°N overlapping ... -
Sill to surface: Linking young off-axis volcanism with subsurface melt at the overlapping spreading center at 9 degrees 03 ' N East Pacific Rise
(EARTH AND PLANETARY SCIENCE LETTERS, 2013-05) -
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 ...
