Recent research indicates that Earth's mantle contains two large blobs, remnants of Theia, the ancient planet whose collision with Earth led to the moon's creation. This discovery offers fresh insights into the moon's formation and Earth's early history. In the 1980s, geophysicists made a startli

The remnants of an ancient planet that collided with Earth to form the Moon lie deep within the earth, according to a new model from Caltech researchers and collaborators.

Tuscaloosa AL (SPX) Apr 10, 2023 - Through global-scale seismic imaging of Earths interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floo

Researchers from The University of Alabama discovered a dense layer of ancient ocean floor, or ultra-low velocity zone (ULVZ), between Earth's core and mantle using seismic imaging. These underground "mountains" could play a key role in heat escape from the core and the planet's magnetic field. T

A layer between Earth's mantle and core—approximately 2,000 miles underground— likely dense and thin, submerged under the ocean floor has been identified using large-scale seismic imaging, according to a new study published in Science Advances, on April 5.

Through global-scale seismic imaging of Earth’s interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published today in Science Advances.
