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 blobs are both hotter and ...

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 ...

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 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 ...

Massive Blobs Located in Earth's Mantle Could be a 'Diamond Factory,' According to Scientists Scientists believe that there's a diamond factory in our planet's mantle.

The blobs have been observed sending up "mantle plumes" -- columns of magma -- towards the Earth's surface, and have also been linked to the evolution of supercontinents.

This showed that some material from Theia initially sank to the bottom portion of Earth’s mantle and that more of Theia piled up there over time, forming the blobs. The authors reported these ...

A vast, ancient slab of seafloor plunged underneath the Pacific Ocean and has hovered in Earth’s mantle for more than 120 million years, a new study suggests ...

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.
