英文摘要<正>Chemical and isotopic data of the lava samples dredged in the southern Bach Ridge and the northern Italian Ridge of the Musicians Seamounts province,northeast of Hawaii.Although most of the samples analyzed are generally altered,a few are fresh.The latter exhibits similar geochemical and isotopic characteristics to normal MORB (Mid-Ocean Ridge Basalts).There are systematic geochemical trends from hotspot to mid-ocean ridge in the province.Incompatible element and isotopic variations suggest that the flow field had at least two distinct parental magmas,one with higher and one with lower MgO concentrations.The two parental magmas could be related by a magma mixing model.The major and trace element modeling shows that the two parental magmas could not have been produced by different degrees of melting of a homogeneous mantle source,but they are consistent with melting of a generally depleted mantle containing variable volumes of embedded enriched heterogeneity enriched interbeds.
