DOI: 10.1007/s00410-017-1388-3
Abstract: The extreme depletion of the Earth’s mantle in sulfur is commonly seen as a signature of metal segregation from Earth’s mantle to Earth’s core. However, in addition to S, the mantle contains other elements as… read more here.

DOI: 10.1016/j.chemgeo.2021.120350
Abstract: Abstract The numerous chemical and isotopic studies of oceanic basalts have shaped our perception of mantle geochemistry over the last six decades. As partial melts of Earth’s mantle, basalts are indirect tracers of mantle composition.… read more here.

DOI: 10.1016/j.epsl.2017.04.029
Abstract: Abstract The Moon and the Earth's mantle share many chemical and isotopic traits, leading to the prevailing theory that they were formed from similar material. Iron is one element that shows apparent differences between the… read more here.

DOI: 10.1038/ngeo2902
Abstract: The extent to which water and halogens in Earth's mantle have primordial origins, or are dominated by seawater-derived components introduced by subduction is debated. About 90% of non-radiogenic xenon in the Earth's mantle has a… read more here.

DOI: 10.1038/s41561-019-0446-z
Abstract: Partial melting of Earth’s mantle generates oceanic crust and leaves behind a chemically depleted residual mantle. The time-integrated composition of this chemically depleted mantle is generally inferred from basalts produced at mid-ocean ridges. However, isotopic… read more here.

DOI: 10.1073/pnas.1809060115
Abstract: Significance With the exception of volatile elements, which are strongly depleted and isotopically fractionated, the Moon has chemical and isotopic signatures that are indistinguishable from Earth’s mantle. Reconciliation of these properties with Moon formation in… read more here.

DOI: 10.1073/pnas.2209399119
Abstract: Significance There is no direct access to the deep Earth mantle. Therefore, insights into the deep mantle composition rely on indirect observations from geophysics. We exploit seismic datasets of compressional and shear waves reflected at… read more here.
