New simulations reveal that an ancient ocean of magma located above the Earth's core continues to shape the planet's ...

Pillars of hot rock appear to connect continental-size moving blobs at the bottom of Earth's mantle to giant volcanic eruptions at its surface.

Learn more about BLOBS, mantel plumes 1,500 miles into Earth's mantel that contribute to massive volcanic eruptions on the surface.

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

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

Many people envision Earth’s structure as a tidy, layered system: the thin crust on the surface, the thick mantle below, and the core at the center. But beneath our feet lies a world far more ...

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 ...

Water driven toward Earth's center by plate tectonics could lead to the creation of diamonds at the boundary between the core and the mantle.

Geologists Uncover Remnants of Earth’s Mantle That Have Lasted Over 2.5 Billion Years New research suggests that a discrepancy in rocks shows they endured extreme heat, and reveals more about an ...

Researchers say the rocks recovered from the mantle bear a closer resemblance to those that were present on early Earth rather than the more common rocks that make up our continents today.

Two enormous continent-sized "islands" found buried deep inside the Earth's mantle are challenging our ideas about our planet's inner workings. These unexpected regions of the Earth's innards ...

Geoscientists drilled more than 1 kilometer below the ocean's floor to collect an unprecedented amount of rock from the Earth's mantle.
