A large number of N-body simulations of the giant-impact phase of planet formation, combined with the measured concentrations of highly siderophile elements in Earth’s mantle, reveal that the Moon must have formed at least 40 million years after the con

What is the most abundant element in the Earth's crust? What are the characteristics of the Earth's crust, mantle, and core? What is the state of matter of the Earth's mantle? What elements comprise the largest portion of the Earth's biosphere?
The considered investigation is concerned with a reexamination of the question of the distribution of siderophile elements in the earth's upper mantle, taking into account a more unified data base which is now available. A comprehensive suite of ultramafic inclusions was collected as part of the ...
A theoretical model and numerical simulation(i.e.,Zhu et al.2019)demonstrates that the Earth’s lower mantle was intrinsically stratified for helium(He)by thermal diffusion owing to adiabatic temperature gradient in the Earth.This finding helps to explai
A plate model for the simulation of trace element fractionation during partial melting and magma transport in the Earth's upper mantle We propose a new plate model for the simulation of trace element transfer during magmatic and metasomatic processes taking place in the Earth's upper mantl... ...

Investigations into the compositional model of the Earth, particularly the atypical concentrations of volatile elements within the silicate portion of the early Earth, have attracted significant interest due to their pivotal role in elucidating the plane
