“…8a). Both andesites and dacites exhibit high Pt/Pt* (Pt anomaly), (Pt/Ir) N and Re/Os ratios higher than those of chondrites and primitive mantle (Barnes et al, 1988;McDonough and Sun, 1995), but similar to those of the ; (e) Th/La vs. Th (Plank, 2005); (f) Nb/Ta vs. Nb (Rudnick et al, 2000). Upper crust and marine sediments are from Plank (2005), Plank and Langmuir (1998), and references therein.…”

“…To systematically compare the average metal composition of each type of disseminated sulfide mineralization, whole-rock metal contents were recalculated to 100% sulfides ( Barnes et al 1985) are likely indicative of the higher partition coefficient of these metals into the sulfide melt. Recent experimental work (e.g., Francis 1990; Peach et al 1990) and numerical modelling (e.g., Lesher and Campbell 1993; have shown that the partition coefficient of Cu into sulfides (i.e., -1000-2000) appears to be significantly greater than that of Ni (i.e., …”
