Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

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 ...

This study is led by Prof. Yong-Fei Zheng at University of Science and Technology of China. It focuses on the development of tectonic processes along convergent plate margins through inspection of ...

As an undergrad at MIT in the 1950s, Lynn Sykes ’59, SM ’60, became interested in the theory of continental drift, which held that the world’s great landmasses had wandered across Earth over time. The ...

Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. Her colleagues in ...

"There's a lot of work that seems to suggest that early in Earth's history plate tectonics wasn't actually the dominant way in which the planet's internal heat gets released as it is today through the ...

We’ve known for a while that Mars was once a wet world. But there’s always been a geological puzzle regarding how and where that water moved. On Earth, rivers are largely driven by plate tectonics.
