Productive and non-productive intrusive of Oligocene-Miocene age with similar mineralogical composition in Kerman porphyry copper belt exhibited important geochemical differences in terms of trace and rare earth element geochemistry. The productive intrusives are best characterized by low contents of MnO (&le0.1 wt.%), Y(&le18ppm), &SigmaHFSE (&le۱۰۰ppm), heavy rare earth elements (Yb&le1.9 ppm), high Sr content(&ge406-1015ppm), high (Sr/Y&ge30), significant REE fractionation (La/Yb&ge20), as well as positive Eu anomalies(Eu/Eu&ge1), when compared with non-productive intrusives(MnO&ge0.1wt.%,Sr=184-576ppm,Y=12-50ppm, Sr/Y<30, La/Yb<15,Eu/Eu*<1).These signatures are indicative of hydrous and oxidized magmas that formed in a condition which has been different from that of the non-productive intrusives. Based on the present study, the discrimination diagrams which can be used as a tool for identification of productive intrusives, where they are accompanied by nonproductive intrusives, in other copper provinces in Iran, are as follows: MnO-Y, &SigmaHFSE-Y, Sr/Y-Y, Sr/Y-SiO2 , La/Yb-SiO2, La/Yb-Yb, Eu/Eu*-SiO2.
