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 SP - 461 EP - 482 AU - Shafiei, B.
