The Earth Has Two Mysterious Protrusions On Its Core And They’re Not The Same
The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...
The Earth’s Core Is Not as Solid As We Thought, Yet Another Study Speculates
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

Experts are baffled by structures under Pacific that shouldn't exist
According to current scientific theories, the anomalous material in the lower mantle, about 600 miles (1,000km) beneath the water, 'should not be found' there. Described as a 'major mystery', the ...
Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
In the uppermost lower mantle, seismic anisotropy is ubiquitous near subducting slabs, where shear waves with horizontal ...

MFM simulation of the canonical Moon-Forming giant impact (VIDEO)
Here different colors trace different components of Gaia and Theia. The lower mantle of Gaia, denoted by the dashed circle with a radius of 0.8 Earth radii (RE), is only marginally contaminated by ...
