Light Fe isotopic fingerprints of serpentinite-derived fluids recorded by metasomatized mafic dikes in the subducted oceanic lithosphere

Tables S1 provides compiled major element compositions of meta-serpentinites in literatures. Tables S2–S3 are detailed data on major element, trace element, and Fe isotope compositions of the reference materials and studied samples, respectively. Table S4 shows representative major mineral compositions of the (meta-)rodingites. Table S5 summarizes the used parameters for the fluid-rock interaction modelling.
