Scientific paper

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 + or - 44 Myr is indicated for the lavas, 400 Myr older than intruding granites, and predating gneisses that have been proposed as basement rocks.
