A study led by geoscientists at the University of Sydney has revealed why some ancient continental edges became fertile sites ...

SYDNEY: Ancient subduction zones played a key role in forming some of the world's richest deposits of copper, zinc and lead, ...

A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's ...

One longstanding enigma in geology is how one tectonic plate can break Earth's rock-hard shell and begin diving under another in the process known as subduction. "We now know how subduction nucleated ...

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 ...

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 ...

Plate tectonics requires the formation of plate boundaries. Particularly important is the enigmatic initiation of subduction: the sliding of one plate below the other, and the primary driver of plate ...

Understanding the origins of the Ring of Fire, the most seismically active place on Earth, is famously difficult as geologic evidence is destroyed in the process. Now a new study suggests that ...

Recent seismic imaging off Vancouver Island has revealed something extraordinary: a tear in the subducting oceanic plate beneath the Cascadia Subduction Zone. The finding briefly raised the public’s ...

Subduction zones have recurrently formed on Earth. Previous studies have, however, suggested that they are unlikely to start in the interior of a pristine ocean. Instead, they seem to be more likely ...
