The mantle, a zone between our planet’s thin crust and the molten core, features 1,800 miles (2,900 kilometers) of mostly solid rock, with a consistency like thickened caramel that scientists ...

Recent research, using cutting-edge Full-Waveform Inversion (FWI) technology, has revealed that the Earth’s mantle — a massive layer stretching nearly 2,900 kilometers deep — is a chaotic ...

Here’s how it works. Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these ...

Both supercontinents formed over what is now the African domain A new study reveals that Earth's mantle is divided by the Pacific Ring of Fire, a geological scar reflecting the formation and ...

A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's ...

Long-lost remnants of tectonic plates have been discovered sunken deep inside the Earth's mantle. These plate remains were found lurking underneath the center of other continental plates ...

For example, they may be made of crust-like material left over from the mantle's creation 4 billion ... researchers used a new method, known as full-waveform inversion, which uses computer models ...
