(Table 3) Isotope ratios of Sr, Nd and Ce and LREE concentrations in Pacific ...

Isotope ratios of Ce, Nd and Sr, and light rare-earth elements (La, Ce, Nd and Sm) concentrations were measured for sixteen N-type MORB samples from DSDP Sites 420, 421, 429,...对取自深海钻探计划（Deep Sea Drilling Project, DSDP）420、421、429等站位的16个正常型洋中脊玄武岩（N-type MORB）样品，测定了其铈（Ce）、钕（Nd）、锶（Sr）的同位素比值，以及轻稀土元素（light rare-earth elements，La、Ce、Nd和Sm）的浓度。
