The island of Tahiti, the largest in French Polynesia, comprises two major volcanoes aligned
NW‐SE, parallel with the general trend of the Society Islands hotspot track. Rocks from this …

Geological mapping, accurate K/Ar dating and geochemical analyses of lavas allow a
detailed reconstruction of the geological history of Tahiti-Nui Island (French Polynesia). The …

Abstract The Society Island chain is located within a region of the South Pacific
characterized by anomalously enriched isotopic compositions. The islands of Mehetia and …

A plutonic massif is exposed on a 2.1-km 2 area in TahitiNui caldera (Tahiti Island, Society
Archipelago, French Polynesia). All the rock types are emplaced into the caldera-filling …

Piton de la Fournaise (Réunion, Indian Ocean) is a large active volcano which shares many
features with the Hawaiian volcanoes. Its particularly simple elemental and isotopic …

The island of Maupiti is the top of an eroded volcanic shield surrounded by a large lagoon
and coral reef. The most important part of this shield is made up of alkali basaltic lavas …

New chemical analyses for major elements in 76 Hawaiian rocks are presented and bring
the total number of such modern analyses to about 470. Many determinations of minor …

Geochemical and geophysical data can be used to constrain models of Hawaiian lava
generation. Geochemical data, including radiogenic isotopes, major and trace elements …

We report new trace element concentrations and Sr, Nd, Hf, and Pb isotopic ratios for basalts
from the three lava series of Mauritius. Older Series lavas, which represent the shield …
