Off the coast of Chile and Peru, along the entire western length of South America, the seafloor takes a sharp, steep plunge ...

Researchers uncover how tectonic forces eroded the North China Craton, reshaping views on craton stability over time.

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's ...

The North China Craton (NCC) is a very old and stable geological structure, experiencing deformations since the Mesozoic era.

A new study hints that the mantle may be more uniform than scientists thought. Oceanic crust being subducted into the mantle at plate boundaries, the traditional argument goes, introduces new ...

which is ultimately subducted into the mantle source regions of island arc magmas and then incorporated into the resulting island arc basalts. Bucholz studies how different reservoirs on Earth ...

“The general idea is that mantle blobs are likely pushed around by subducted slabs. The two main blobs are surrounded by ‘graveyards’ of subducted slabs,” Cottaar says, referring to the ...

After more than 300 million years, these subducted slabs could be transported back to the upper mantle via mantle upwellings. "This process may have fundamentally altered the composition of the ...

"This thickened area is like a fossilized fingerprint of an ancient piece of seafloor that subducted into the Earth approximately 250 million years ago," Wang said. "It's giving us a glimpse into ...
