PERIDOTITES found on the sea floor are widely believed to be residues left by mid-ocean-ridge basalt (MORE) melting. As such, their composition should provide insights into the nature of the sub-oceanic depleted mantle. But although these abyssal peridotites occur in mid-ocean ridge fracture zones1,2, there is little other evidence in support of their genetic link with MORB, and doubts about it have been raised3–5. Radiogenic isotopes should be able to provide a powerful test of the hypothesis… CONTINUE READING
