Strange features of a collision point between pieces of Earth's crust are evidence that the structure may be nearing its end, ...

The discovery, made just off the coast of Vancouver Island in the Pacific Ocean, shows that a section of the oceanic crust is ...

In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this ...

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, ...

For the first time, scientists have seen a subduction zone actively breaking apart beneath the Pacific Northwest. Seismic ...

Geological processes shape the planet Earth and are in many ways essential to our planet's habitability for life. One important geological process is plate tectonics – the drifting, colliding and ...

Ancient rocks on the coast of Oman that were once driven deep down toward Earth's mantle may reveal new insights into subduction, an important tectonic process that fuels volcanoes and creates ...

BUFFALO, N.Y. — At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from ...

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 ...
