Variation of Pd and Ni contents of the disseminated sulfide mineralization from (A) East Lake, (B) Zone 3, (C) Zone 2, (D) Katinniq, (E) Zone 5-8, (F) Zone 13-14, (G) West Boundary, (H) Boundary, and (I) Donaldson zones of Raglan deposit. Pd and Ni contents are presented on a 100% sulfide basis. Data are traced by nonparametric density contour quantiles. The red line denotes the sulfide compositions that would be at equilibrium with the sulfide-saturated silicate magma at different temperatures with infinite R factor. The red circles along the blue model trend line represent modeled sulfide compositions at temperature (T) = 1,301°C under variable R factors (labeled in the diagram). The silicate melt composition at a given temperature is modeled by thermodynamic modeling software AlphaMELTS. The offset of some zones (e.g., Zone 2, Boundary, Donaldson) to higher Ni contents suggests that they formed by reaction of sulfide melt with the komatiite at earlier stages of magma evolution.
