Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

Front Matter -- Thermal Structure of Deep Earth. Melting of Fe Alloys and the Thermal Structure of the Core / Rebecca A Fischer -- Temperature of the Lower Mantle and Core Based on Ab Initio Mineral ...

Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a ...

Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of “proto Earth” ...

The lower mantle extends from a depth of approximately 660 to 2,900 km beneath Earth’s surface and is composed primarily of silicate perovskite (bridgmanite), ferropericlase and calcium silicate ...

New research is reshaping how scientists understand the earliest days of Earth’s formation—suggesting that the deep interior of our planet locked in its defining features just 100 million years after ...

For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

A joint research group has identified that the spatial scale of "heterogeneity" in the upper mantle, caused by a large-scale flow called a mantle plume rising from deep Earth, is less than 10 ...

The first continents of our planet arose not from fresh mantle material, but from recycled ocean rocks. This conclusion was ...
