Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

A new study suggests that tiny, mineral grains—squeezed and mixed over millions of years—set in motion the chain of events that plunge massive tectonic plates deep into the Earth's interior. The study ...

A team of geoscientists has identified a subtle but powerful force driving mountain building and compression of Earth's crust in Japan and neighboring regions. The so-called same-dip double subduction ...

The dying Mediterranean Sea may have contaminated the Atlantic with a subduction zone. One day, it could help destroy the vast ocean. Oceans come and go over hundreds of millions of years. New ones ...

Earth was mostly devoid of oxygen for much of its 4.5 billion year lifetime. That is, until certain processes started to allow for the eventual buildup of oxygen up to the levels we have now (around ...

A new study suggests that tiny, mineral grains — squeezed and mixed over millions of years — set in motion the chain of events that plunge massive tectonic plates deep into the Earth’s interior. The ...
