The article discusses recent findings related to the isotopic anomalies in mantle rocks, revealing that the Earthâs mantle has retained chemical heterogeneities since its early formation. The preservation of these anomalies supports the notion of a primordial magma ocean that significantly influenced the Earthâs geological evolution. This solidification process has implications for the seismic foundation of the deep mantle, including phenomena such as large low shear velocity provinces (LLSVPs). The study emphasizes the importance of investigating magma ocean solidification to thoroughly understand the mantle's long-term evolution and its current structure.
The solidification of a deep primitive magma ocean explains early silicate differentiation, current seismic structures, and the dynamics of Earth's mantle and core.
Isotopic anomalies indicate that the Earth's mantle preserves chemical heterogeneities dating back to its infancy, linked to the preservation of early geochemical reservoirs.
