Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

Ancient rocks in Australia suggest Earth’s tectonic plates were already moving 3.5 billion years ago, reshaping understanding ...

A unique rock formation in China holds clues that tectonic plates subducted, or went underneath other plates, during the Archean eon (4 billion to 2.5 billion years ago), just as they do nowadays, a ...

Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and ...

In 2016, the geochemists Jonas Tusch and Carsten Münker hammered a thousand pounds of rock from the Australian Outback and airfreighted it home to Cologne, Germany. Five years of sawing, crushing, ...

Utrecht University PhD candidate Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. She reconstructed ...

Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be subducted deep into the mantle. Then comes the Boring Billion, when even mantle ...

A 5.8 magnitude earthquake that struck east Victoria today is not the first, or most destructive, to shake Australia's foundations.

Silfra is a fissure in Thingvellir National Park, Iceland, where visitors can snorkel or dive between the North American and ...
