Ori-normalized CSE systematics in Shatsky Rise magmas as function of Dsulf/sil. Chalcophile element differences between two populations of Tamu Massif and Ori Massif samples ([M]Tamu/[M]Ori; see Fig. 1) are plotted with respect to their Dsulf/sil (values taken from Jenner1, and references therein). With the exception of Re, which shows evidence of degassing43, highly chalcophile (Dsulf/sil > 300) elements show a strong correlation with Dsulf/sil, consistent with the interpretation that the Ori Massif samples are sulfide-saturated. Select incompatible, major and non-volatile elements are distributed around an [M]Tamu/[M]Ori of 1, suggesting that the offset in chalcophile element contents between the Tamu and Ori Massifs at comparable [MgO] cannot be attributed to source heterogeneity and/or variations in the degree of partial melting. VICE = very incompatible elements (see ref. 38)
