The sulphur-poor portions of the dry condensed Cu-Fe-Pd-S system were Studied at 1000 degrees C, 900 degrees C and 725 degrees C by synthesis in evacuated silicate glass tubes, along with textural observations and electron microprobe analyses of equilibrated reaction products. Sulphide melt coexists with Cu-Fe-Pd alloys, bornite, Fe1-xS and iss (intermediate solid Solution, Cabri, 1973) and Pd4S. Compositional data were obtained for the associations bornite-alloy-melt, pyrrhotite-alloy-melt and for immiscible Cu-rich sulphide melts. partition coefficients for all three metals were derived for the association alloy-melt. Formation of the two new Cu-Pd alloy Minerals, skaergaardite and nielsenite, is discussed in terms of the present findings.
