Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Geologists have discovered remnants of Earth's mantle that have persisted for over 2.5 billion years. The ancient rocks were less oxidized than modern ones, indicating that they were exposed to ...

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 ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

The discovery bolsters the theory that meteorite impacts played an important role in Earth's early geological history Margherita Bassi Volcanologists are closely monitoring the 11,070-foot-tall ...

It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

This cut-away diagram of Earth's interior demonstrates the different rates of rotation of the inner core relative to the mantle and crust, and how those rotations appear to someone on the planet's ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...

The Earth is made up of different layers ... Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and ...
