Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...

The opening and closing of the Rocas Verdes Basin, a back-arc basin in Patagonia, as described by researchers at The University of Texas at Austin in a study published in Geology. Panels B and C ...

Scientists have identified an unusually thick rock layer deep beneath the Bermuda Triangle, revealing a geological feature unlike anything previously documented. The structure, measuring about 20 ...

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 ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...
