Water, major and trace element systematics of mantle xenoliths from Savai‘i and Ta‘ū islands (Samoa)

Abstract: Major (by electron microprobe), trace element (by Laser Ablation ICPMS) and structural hydrogen (i.e. “water”; by polarized FTIR) concentrations of nominally anhydrous minerals and spinels from peridotite xenoliths of Savai‘i and Ta‘ū (Samoa). The goal of this data set is to constrain the effects of metasomatism and depletion on water systematics of the oceanic lithosphere.
