“…Therefore, other residual phases retaining Mo must have been present during sediment melting. (Freymuth et al, , 2015Gaschnig et al, 2017;König et al, 2016;Voegelin et al, 2014;Wille et al, 2018) and MORB average (Gale et al, 2013). Sulfides represent another preferential host phases for Mo (e.g., Li & Audétat, 2012), and the net partitioning effects in these Ca-poor sediment melts (Skora et al, 2017) can produce Ce/Mo values consistent with those required for the TMP magmas (Figure 6c).…”
