Nd- and Sr- isotope ratios of oceanic basalts

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...已对37件大洋玄武岩样品测定143Nd/144Nd比值，典型测量精度为±(2~3)×10^-5（2σ）。所分析样品涵盖洋岛样品、拖网采集及岩心取心的海底（原文未完整收尾）。
