To investigate this, a team of researchers in Japan performed well-controlled deformation experiments on phase D aggregates ...

A record-breaking deep earthquake registered in May 2015 offshore of Japan likely was not a tectonic event but triggered by a ...

A re-examination of the 2015 Bonin Islands earthquake disproved earlier claims of a record-breaking deep aftershock in the ...

A computer model visualization of material in the lower mantle. This material resembles a sunken plate but cannot come from subducted plates because of the lack of nearby subduction zones.

The fate of carbonate in oceanic crust subducted into earth’s lower mantle. Earth and Planetary Science ... are efficient agents of chemical mass-transfer in the upper mantle and transition zone, and ...

Scientists have discovered the "fossilized fingerprint" of a chunk of seafloor that was hiding beneath the Pacific Ocean in Earth's mantle. A new study shows that this fingerprint corresponds to a ...

A team of geophysicists created a detailed model of Earth's lower mantle using earthquake waves. This indicates the presence of zones of rocks that are colder, or have a different composition ...

The magnitude 7.9 Bonin Islands earthquake sequence, which ruptured deep within the earth near the base of the upper mantle, did not include an aftershock that extended to record depths into the lower ...
