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.

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 ...

Two Continent-Sized 'Blobs' Hidden Deep Inside Earth's Mantle Continue To Baffle Scientists From Decades Earth and many of its features are still an enigma for experts. The most prominent mystery ...

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 ...

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

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 ...

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 ...

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 ...

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 ...
