A sideways flow of hot mantle rock, not a deep plume rising from near Earth’s core, may be feeding one of the planet’s most ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Many seismologists and researchers have long believed the Earth possesses a fast flowing and well-mixed mantle. But that theory may require some revisions according to new findings from researchers at ...

A research team from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) has developed a ...

Researchers created a seismic map of Earth's interior beneath the southeastern Pacific Ocean and discovered an ancient slab of oceanic crust that appears to be stuck midway through the mantle. When ...
