Synthetic evolution of Sr-Nd-Pb isotopes in the'' mantle plane''-model and interpretation
地幔Sr-Nd-Pb同位素演化的综合模型与n维同位素空间 “地幔面”的地质意义

In the n-dimension Sr-Nd-Pb isotopic space,almost all the oceanic basalts(MORB+OIB)over the world fit on a pseudo plane,which was called "mantle plane".The " mantle plane" accounts for the characteristics of the majority of the mantle arrays. However,as one of the most important and earliest noticed factors of mantle chemical geodynamic evolution,"mantle plane" are poorly known even now.Here we present a comprehensive model of Sr-Nd-Pb isotopic evolution in the mantle.In the mantle source of magmas,isotopic...
