Computer simulations show that mantle material from Theia, a proto-planet theorized to have struck the proto-Earth in the Moon-forming giant impact, may be the source of Earth’s basal mantle anomalies. Seismic images of Earth’s interior have revealed two continent-sized anomalies with low seismic velocities, known as the large low-velocity provinces (LLVPs), in the lowermost mantle^ 1 . The LLVPs are often interpreted as intrinsically dense heterogeneities that are compositionally distinct from…

A crystallizing dense magma ocean at the base of the Earth’s mantle

It is shown that a stable layer of dense melt formed at the base of the mantle early in the Earth’s history would have undergone slow fractional crystallization, and would be an ideal candidate for an unsampled geochemical reservoir hosting a variety of incompatible species for an initial basal magma ocean thickness of about 1,000 km.

Forming a Moon with an Earth-like Composition via a Giant Impact

Computer simulations show that a giant impact on early Earth could lead to a Moon with a composition similar to Earth’s, and simulate impacts involving larger impactors than previously considered that can produce a disk with the same composition as the planet's mantle, consistent with Earth-Moon compositional similarities.

Thermochemical structures beneath Africa and the Pacific Ocean

Numerical models of thermochemical convection in a three-dimensional spherical geometry using plate velocities inferred for the past 119 million years show that Earth's subduction history can lead to thermochemical structures similar in shape to the observed large, lower-mantle velocity anomalies.

Upside-down differentiation and generation of a ‘primordial’ lower mantle

It is suggested that a necessary by-product of whole-mantle convection during the Earth’s first billion years is deep and hot melting, resulting in the generation of dense liquids that crystallized and sank into the lower mantle, which would have ‘primordial’ chemical signatures despite a non-primordial origin.

Immediate Origin of the Moon as a Post-impact Satellite
