Researchers were once unsure whether mantle earthquakes existed. Now they have a global map of this mysterious phenomenon.

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

First global map of mantle earthquakes reveals seismic activity far beneath continents, challenging old ideas about Earth’s ...

A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. A new study from a University of Chicago scientist suggests there may be ...

WASHINGTON (Reuters) - Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and ...

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

The boundary zone between the mantle, the planet's rocky middle layer, and the molten metal core might be a diamond-producing region! According to a recent laboratory experiment, the elements such as ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth's crust. The discovery could help scientists learn more about the movements of Earth's tectonic plates, ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...
