In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

Geoscientists have long puzzled over the mechanism that created the Tibetan Plateau, but a new study finds that the landform's history may be controlled primarily by the strength of the tectonic ...

Convergent plate margins are currently distinguished as ‘accretional’ or ‘erosional’, depending on the tendency to accumulate sediments, or not, at the trench. Accretion and erosion can coexist along ...

Classical plate tectonic theory was developed in the 1960s. It proposed that the outer layer of our planet is made up of a small number of rigid plates separated by narrow boundaries. The surface of ...

The puzzle pieces of tectonic plates are not rigid and don't fit together as nicely as we were taught in high school. A new nstudy quantifies deformation of the Pacific plate and challenges the ...

There's something weird going on in the Atlantic Ocean. Off the coast of Portugal, a tectonic plate may be peeling apart, with the top layer separating from the bottom, a scientist has proposed. João ...

Researchers at Monash University’s School of Geosciences have developed a three dimensional model that uses physics to predict the behaviour of tectonic plates. The model was developed by examining ...
