Exact excerpt

The mean µ142Nd at +3.2 of Fani Maoré can be reproduced by including 8–10(±3)% of Hadean bridgmanite in the source, but reproducing its mean ε143Nd of +3.8 would require only 2–3(±1)%. This demonstrates that a simple mixture of Hadean material and ordinary mantle cannot explain all of the observations and that a third component is needed in the source of Fani Maoré volcanics.
