Helium Isotopes and Helium and Carbon Dioxide Concentrations in Basaltic Vesicles and Glass from the Gulf of Aden New helium isotope results for basalt glasses along the West and East Sheba Ridges in the Gulf of Aden reveal a strong mantle plume signal similar to that observed in the Main Ethiopian Rift, with 3He/4He ranging up to 17 Ra. This signal be David W Graham 10/15/2018 View Details
Key new pieces to the HIMU (high U/Pb) puzzle from olivines and diamond inclusions (South Pacific and Indian Ocean) High-precision EMP analyses on olivine phenocrysts in HIMU (high U/Pb) lavas from Mangaia and Tubuai in the Cook-Austral Islands, South Pacific, and in lavas from Karthala, Grande Comore Island, Indian Ocean, which shows intermediate Nd-Sr- Yaakov Weiss 07/01/2018 View Details
Major, trace element and Sr-Nd-Pb-Hf isotope compositions of Tuvalu Island lavas (Rurutu Hotspot) Major, trace element and Sr-Nd-Pb-Hf isotopic composition of dredged submarine lava samples from the Tuvalu Islands, Southwest Pacific, located between the Marshall/Gilbert Islands and Samoan (western) Seamounts.

Platinum-group elements (PGE), Re, Ni, Cu, Ag and Cd variations along the Reykjanes Ridge and Iceland South-West Neovolcanic Rift Zone, from 50°N to 65°N: Implications on sulfide bearing PGE mantle source heterogeneities and partial melting effects We report on the concentrations of platinum group elements (PGE), Re, Ag and Cd in 53 tholeiitic basalts and one picrite from the Reykjanes Ridge and its extension over Iceland. The purpose is to investigate sulfide bearing PGE mantle sourc Jean-Guy Schilling 09/01/2017 View Details
Major element and trace element and Sr-Nd isotope analyses of arc volcanic rocks from the eastern Mexican Volcanic Belt The datasets presented here include major element and trace element analyses, as well as Sr-Nd isotope analyses of arc volcanic rocks from the eastern Mexican Volcanic Belt with specific focus on calc-alkaline monogenetic volcanoes from the Susanne M.
