Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness.
(Journal of Geophysical Research, 1987-12-01)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 ... -
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 ...
