The contents of such platinum-group elements as Ir, Ru, Rh, Pt and Pd in Jianguo basalts and Wulahada Mg-high andesites were determined using ICP-MS after a nickel sulfide fire assay preconcentration. They display positive slope in the mantle-normalized pattern. The Pd/Ir values higher than those of the primitive mantle suggest the fractionation of PGE in Fuxin volcanic rocks. PGE fractionation in the basalts is attributed to the fact that Ir can be potentially fractionated in spinel and alloys but Pd resides in sulfides during partial melting. The PGE in Wulahada Mg-high andesites might be affected by the phases separated from earlier melts during fractionation. The negative Pt anomaly in Fuxin volcanic rocks probably results from Fe-Pt alloys residing in the mantle.
