Data for <b><i>Deep mantle cycle of chalcophile metals and sulfur in subducted oceanic crust</i></b>

This dataset includes (1) contents of Cu, Ag, Au, Re and PGEs and other compositions of Hannuoba alkaline basalts in this study, Cenozoic alkaline basalts from eastern China that compiled from the literature used in this study and standards; (2) major compositions of Cpx separated from Hannuoba alkaline basalts and calculated P-T; (3) Silver mass balances which calculated from the IODP Hole 1256D sulfide population and modeling the behavior of chalcophile elements during partial melting.
