Scientists are observing a new ocean forming in Africa's Afar region, a unique geological hotspot. Early magnetic surveys ...

An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction ...

The recycling of the Earth's crust in volcanoes happens much faster than scientists have previously assumed. Rock of the oceanic crust, which sinks deep into the earth due to the movement of tectonic ...

The formation and composition of oceanic crust remain central yet unresolved questions in plate tectonics. While seismic data suggest a globally uniform crustal thickness (~6 km), petrological ...
