Sm–Nd isotope systematics in mafic–ultramafic lavas from the Norseman–Wiluna greenstone belt, Western Australia, have been reinvestigated. A previous age based on mixing lavas and granites is not confirmed: instead, a Sm–Nd age of 3,262 ± 44 Myr is indicated for the lavas, 400 Myr older than intruding granites, and predating gneisses that have been proposed as basement rocks. |
