Really interesting work! I have two questions - 1) Are there any systematic variations within a single island between d34S and the Mg# of the pyroxene host? It would be nice to catch the differentation/degassing process in the act, and also understand the several per mil variation in any one island. 2) I didn't quite understand the model for the interstitial sulfides - are they residual to degassing, or precipitated from the exsolved vapor/fluid? What is the oxidation state of the magmatic system - this will determine whether the exsolved fluid will be heavier or lighter than the magmatic liquid. - Terry Plank, LDEO

nice work! Why do you think S isotopes hovers around zero in these cumulates? Cin-Ty
