Early formed high-Mg# olivine phenocrysts during evolution of MORB magmas usually host melt inclusions, which record im-portant information about the early-stage evolution of magma.Five MORB samples from near East Pacific Rise (EPR) 13°N vary little in K/Ti (0.07?0.12), Tb/Lu (1.72?1.84) and Sm/Nd (0.310?0.332) and have similar REEs patterns, indicating that depleted upper mantle has similar mineral composition.Sixty-five initial melt inclusions derived by correcting olivine fractionation and FeO-Loss show ... 相似文献
