They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the boundary between Earth's mantle and its outer core, some 1,900 miles (3,000 kilometers) beneath the surface.

Lava around the world may come from the same magma ancestor deep in Earth's middle layer, new research finds. The study ...

In this illustration, parts of the ancient planet Theia sink and accumulate at the bottom of the Earth’s mantle. This forms two ‘blobs’ called large low-velocity provinces (LLVPs) deep ...

As the hypothesis goes, from the chaos of this collision coalesced Earth (and the Moon), and pieces of that ancient smash up are still buried deep in Earth’s lower mantle in two large blobs ...

Beneath the Earth's crust, where the mantle meets the outer core, there is a collection of unexplainable rock blobs that are hundreds of miles long. This isn't the exposition for a sci-fi flick ...

For decades, scientists have been baffled by two large, mysterious blobs in Earth’s mantle. These rock formations are thousands of kilometres long and slightly denser than their surroundings ...

Some of Theia's mantle could have persisted in Earth’s mantle and ultimately clumped and crystallized to form the two distinct blobs detectable today at Earth's core–mantle boundary; other ...

In these areas, generally called "blobs", waves travel more slowly than through the surrounding lower mantle. Under Africa, the area known as "Tuzo" is thought to be about 800 kilometers (497 ...
