Olivine, orthopyroxene, clinopyroxene, and spinel major and trace element data for peridotites from the forearc of the Tonga Trench
Major element data for olivine, orthopyroxene, and spinel within peridotites from the Tonga Trench, used to calculate oxygen fugacity. Major element data was collected by EPMA. Fe3+/tFe values for spinel were determined by stoichiometry and corrected using a suite of calibration spinels previously run by Mössbauer (following the technique presented in Davis et al., 2017).
Trace element data for clinopyroxene, orthopyroxene, and olivine within peridotites from the Tonga Trench. Data was collected using LA-ICPMS.
