Evolution of continental lithospheric mantle beneath Hainan Island, China: Evidence from Os-Hf-Sr-Nd isotopes and PGE systematics of peridotite xenoliths

Petrography, whole-rock major and minor elements, temperature of Hainan mantle xenoliths, determined by ICP-OES. Major element and trace element concentrations of clinopyroxene and orthopyroxene separates from Hainan mantle peridotites are analyzed by EPMA and LA-ICP-MS, respectively.Highly siderophile element abundances and Re-Os isotopic compositions of whole-rock and olivine separates, analyzed by HR-ICP-MS and N-TIMS, respectively.Sr-Nd-Hf isotopic compositions of clinopyroxene and coexisting orthopyroxene separates, as well as calculated whole-rock compositions, determined by MC-ICP-MS.Major oxides of olivine and spinel separates from Hainan mantle xenoliths.These dataset can help to precisely characterize the deep processes (melting and metasomatism) and constrain the timing of melt extraction.
