New measurements of Nb and other trace elements in fertile peridotite xenoliths are reported. The data show that the Nb/Ta ratio is chondritic, whereas Nb/Tb ratios are higher than chondritic. High Nb/Tb ratios are characteristic of sources and/or residues of divergent-margin and intraplate magmatism. Compared with primitive mantle, these peridotites show a systematic and uniform depletion of the highly incompatible elements. The depleted patterns are apparently inconsistent with these peridotites being sources or residua from convergent-margin magmatism. These data may indicate that the continental lithospheric mantle does not possess a Nb enrichment to complement the depletion found in the continental crust and island-arc basalts.
