Fig. 2: Trace element compositions of samples investigated in this study.

Trace element patterns normalized to primitive mantle concentrations (a, c, e), and rare earth element patterns normalized to chondritic values (b, d, f) for melt inclusions and their host whole rocks. Normalized-primitive mantle and -chondrite values are from ref. 94. There are two different groups of melt inclusions in NSP-21 and NSP-24, respectively.
