Fluid metasomatic rocks with extremely low δ26Mg values in the subducted oceanic lithosphere: Implications for mantle Mg isotope heterogeneity and the origin of low-δ26Mg magmas

The files contain: Table1 for Whole-rock Mg-O-Sr-Nd isotope compositions of the studied Ti-clinohumite dikelets, metarodingites and related serpentinites and Table S1 for Whole-rock trace element compositions of the studied samples.
