Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Subduction initiation marks the birth of a convergent plate boundary, where one tectonic plate begins to descend beneath another into the mantle. This process underpins the global plate-tectonic cycle ...

A groundbreaking study in Science Advances reveals that Earth's tectonic plates are breaking apart under the Cascadia subduction zone. Geologists from Louisiana State University and the Lamont-Doherty ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be subducted deep into the mantle. Then comes the Boring Billion, when even mantle ...
