143Nd/144Nd ratios have been determined on 37 samples of oceanic basalt, with a typical precision of +/- 2-3 * 10**-5 (2 sigma). Ocean island and dredged and cored submarine basalts are included for which reliable measurements of 87Sr/86Sr ratios exist in the literature or have been measured as part...
