Figure 5. He/ He vs. (a-left) buoyancy flux, (b-opposite page, upper) Lithosphere age. (e-opp. page, lower) Plate speed. Points show the highest e/" He ratios at eaeh island with dashed lines extending to the lowest values. Only crushing analyses are used to avoid post-eruptive addition of cosmogenie e and radiogenic ""He. Buoyancy flux is taken direetly from Davies (1988) or ealeulated from Sleep (1990) assuming an excess plume temperature of 200°C. He data are from Kurz et al. (1982a, 1983) for Gough, Tristan da Cunha and Hawaii Hilton et al.

The islands of Tristan da Cunha and Gough in the South Atlantic are notable because they have Pb, Nd and Sr isotope characteristics similar to hypothetical values for the bulk silicate Earth. Kurz et al. (1982a) showed that He/" He was 5-6 Ra at these islands, lower than MORB values (Fig. 10a), indicating that a primitive mantle reservoir is not involved. On this basis, Kurz et al. (1982a) suggested that recycled crust was present in the Tristan and Gough mantle source regions.
