英文摘要The early Earth is one of the frontier topics in Earth Sciences, involving numerous key scientific questions, such as the formation of moon-earth system, core-mantle differentiation, and formation of proto-atmosphere and hydrosphere. The mantle is the main component and the largest chemical reservoir of the Silicate Earth. The evolution of early mantle provides important constraints for revealing major geological events, such as accretion of the early Earth, core-mantle differentiation, and mantle-crust differentiation. Chemical heterogeneity in the early Earth mantle has been gradually discovered in recent years. On the basis of overview of the evidence of rare gas, neodymium and tungsten isotopes for the early mantle heterogeneity, this paper discusses the possible geodynamic processes (i.e., early mantle differentiation, late accretion, and core-mantle interaction) to form the early mantle heterogeneity. Furthermore, it also points out that using the high precision isotopic data, combined with geophysics and experimental petrology, to reveal the structure of core-mantle boundary and the material exchange process between mantle and core is the important issue of the early mantle heterogeneity in the future
