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 today in AGU Advances, AGU’s ...
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 ...

Australia racing poleward 3.5 billion years ago is the oldest direct evidence of tectonic plate movement
Direct evidence of the movements of tectonic plates has been found in some of the world’s oldest rocks, in the Pilbara Craton, Western Australia. This evidence dates back 3.5 billion years; the ...
The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...
A Brown University study provides new evidence that the icy shell of Jupiter’s moon Europa may have plate tectonics similar to those on Earth. The presence of plate tectonic activity could have ...
Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...
Mars is known for its volcanoes, some of which dwarf the largest volcanoes on Earth. And, although Mars’ volcanoes have been extinct or dormant for millions of years, there’s growing evidence for some ...
Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of ...
