Journal ArticleDOI

Mark K. Reagan,Osamu Ishizuka,Robert J. Stern,Katherine A. Kelley,Yasuhiko Ohara,Janne Blichert-Toft,Sherman H. Bloomer,Jennifer Cash,Patricia Fryer,Barry B. Hanan,Rosemary Hickey-Vargas,Teruaki Ishii,Jun-Ichi Kimura,David W. Peate,Michael C. Rowe,Melinda Woods +15 more
TL;DR: A recent dive with the JAMSTEC Shinkai 6500 manned submersible in the Mariana fore arc southeast of Guam has discovered that MORB-like tholeiitic basalts crop out over large areas.
Journal ArticleDOI
Lead and Helium Isotope Evidence from Oceanic Basalts for a Common Deep Source of Mantle Plumes
Barry B. Hanan,David W. Graham +1 more
TL;DR: The MORB data suggest that the common mantle source is located in the transition zone region, which contains recycled, oceanic crustal protoliths that incorporated some continental lead before their subduction during the past 300 to 2000 million years.
Journal ArticleDOI
Nd‐Sr‐Pb isotopic variations along the Gulf of Aden: Evidence for Afar Mantle Plume‐Continental Lithosphere Interaction
TL;DR: In this article, the authors report on the rare earth and Nd-Sr-Pb isotopic composition of basalts dredged along the Sheba Ridge axis in the Gulf of Aden and its extension into the gulf of Tadjoura and subaerial basalts from the Ardoukoba Rift in east Afar.
Journal ArticleDOI
Contrasting origins of the upper mantle revealed by hafnium and lead isotopes from the Southeast Indian Ridge
TL;DR: It is inferred that the Indian upper-mantle isotopic signature in this region is affected mainly by lower continental crust entrained during Gondwana rifting, whereas the isotope signature of the Pacific upper mantle is influenced predominantly by ocean floor subduction-related processes.
Journal ArticleDOI
Pb isotope evidence in the South Atlantic for migrating ridge-hotspot interactions
TL;DR: In this article, Pb isotopes in basalts erupted along the Mid-Atlantic Ridge suggest that heterogeneities in the upper mantle beneath the South Atlantic are highly structured and dominated by distinct east-west channels connecting the off-ridge plumes with the westward-migrating ridge.
