Journal ArticleDOI
High μ (HIMU) ocean island basalts in southern Polynesia: New evidence for whole mantle scale recycling of subducted oceanic crust
TL;DR: In this paper, major elements, trace elements, and Pb isotopic compositions were determined for ocean island basalts (OIBs) from Polynesia in the southern Pacific in order to document the chemical characteristics of OIB sources and to understand their origin.
Journal ArticleDOI
Isotope and trace element variations in lavas from Raivavae and Rapa, Cook–Austral islands: constraints on the nature of HIMU- and EM-mantle and the origin of mid-plate volcanism in French Polynesia
TL;DR: In this article, the major and trace element and isotope variations in two suites of lavas from the islands of Raivavae and Rapa from the Cook-Austral chain were examined to better constrain the nature and origin of the source(s) of these lavas.
Journal ArticleDOI
Seismic anisotropy and compositionally induced velocity anomalies in the lithosphere above mantle plumes: a petrological and microstructural study of mantle xenoliths from French Polynesia
TL;DR: In this paper, the authors investigated the relationship between petrological processes and microstructure in mantle xenoliths from different hotspots tracks in the South Pacific Superswell region: the Austral-Cook, Society, and Marquesas islands in French Polynesia.
Journal ArticleDOI
Chlorine–potassium variations in melt inclusions from Raivavae and Rapa, Austral Islands: constraints on chlorine recycling in the mantle and evidence for brine-induced melting of oceanic crust
TL;DR: Chlorine abundance variations in oceanic basalts can provide insights into the degassing and volatile recycling history of the mantle as well as shallow melt/hydrosphere interaction as discussed by the authors.
Journal ArticleDOI
Origin of basalts from the Marquesas Archipelago (south central Pacific Ocean): isotope and trace element constraints
TL;DR: Basalts from the Marquesas Archipelago display significant variations according to magmatic type in 143Nd/144Nd (0.512710 −0.4139) and 87Sr/86Sr ( 0.70288−0.70561) suggesting heterogeneities at various scales in the mantle source with respectively the highest and lowest values in tholeiites compared to alkali basalts.
