Comprehensive dataset for the Hujialin ultramafic body in the Sulu orogen: Mineral proportions, whole-rock geochemistry, Sr-Nd-O isotopes, mineral chemistry, and melt/cumulate modeling

This dataset presents a comprehensive geochemical and petrological record for the Hujialin ultramafic body in the Sulu orogenic belt, a major ultrahigh-pressure terrane in eastern China. The data compilation includes mineral proportions (Table S1), whole-rock major and trace element compositions (Table S2), whole-rock Sr–Nd isotopic ratios (Table S3), major and trace element compositions of olivine (Table S4), spinel (Table S5), garnet (Table S6), and clinopyroxene (Table S7), oxygen isotope compositions of whole-rock and mineral separates (Table S8), and modeled melt–cumulate compositions using the MELTS algorithm (Table S9). The dataset integrates newly acquired analyses with previously published data for several garnet-rich clinopyroxenites, allowing a unified comparison across the Hujialin ultramafic suite.
