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 ...

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 ...

The tectonic plates are among the most powerful forces on Earth, exerting tremendous influence over every single life that unfolds on this planet. They are both creators and destroyers, capable of ...

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published in the open access journal AGU ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

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 ...

One of Earth’s defining features is its plate tectonics, a phenomenon that shapes the planet’s surface and creates some of its most catastrophic events, like earthquakes, tsunamis, and volcanic ...

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 ...

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, ...

Plate tectonics – the drifting of continents – may have got under way at least 3.2 billion years ago and could have played a part in the evolution of life, a study of the magnetism of ancient rocks ...

The undersea plate boundary beneath the Strait of Gibraltar, known as the Gibraltar arc, is slowly moving into the Atlantic ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. A team of scientists say they have uncovered evidence of a mysterious tectonic plate beneath northern Canada that some ...
