Appendix for Marine Geology

Appendix data for: Mineralogy and geochemistry of secondary minerals and oxyhydroxides from the Xunmei hydrothermal field, Southern Mid-Atlantic Ridge (26°S). Table S1 The standard minerals for sulfides, oxide and oxyhydroxide during the EPMA analysis. Table S2 The EDS analysis of secondary minerals and oxyhydroxides (wt.%). Table S3 Chemical variations in sulfides, secondary minerals, and oxyhydroxides by EPMA (wt.%). Table S4 Bulk chemical composition (ICP-OES and ICP-MS) of the profile of the weathered sulfides (ppm). Table S5 The trace element variations in pyrite and chalcopyrite using LA-ICP-MS (ppm). Table S6 The pearson correlation analysis of elemets in the oxyhydroxides
