Obvious PGE differentiation of the Emeishan basalts in the eastern rock province is different from that of the primitive mantle.
结果表明,相对于原始地幔,东岩区峨眉山玄武岩的铂族元素发生了较强的分异作用,Os、Ir、Ru、Rh亏损,Pd、Pt则发生富集,相对配分模式为Pd Pt富集型;经球粒陨石及原始地幔标准化的铂族元素配分模式为向左陡倾斜型,具有陡的正斜率,Pd/Ir显著高于原始地幔、球粒陨石、原始上地幔等,而与地幔低度熔融形成的N MORB、大陆拉斑玄武岩等接近,表明峨眉山玄武岩的物质来源为上地幔熔融程度偏低的玄武岩浆。
The fractionation between LREE and HREE and that between Ce, Eu and other rare earth elements are obvious in the profiles.
