Experimental Constraints on the Sulfide

Calculated sulfide-silicate melt D Re are 3.3 to 5.2 10 4, and experiments yielded lower bounds for D Os /D Re of 3, indicating that sulfide-silicate melt equilibrium can fractionate Re from Os. Minimum sulfide melt-chromite partition coefficients are 1,000 or more, indicating that coexisting sulfide melt will be the dominant host for the PGE. Get price
