Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...
AI models used ancient zircons to reveal Earth’s earliest crust chemistry, solving a long-standing geologic mystery. (CREDIT: CC BY-SA 4.0) In Earth’s early days, more than 4 billion years ago, the ...
An illustration depicting the formation of TTGs in a two-stage mantle plume-sagduction model. Geologists from The University of Hong Kong (HKU) have made a breakthrough in understanding how the ...
Fresh evidence suggests early Earth wasn’t locked under a rigid stagnant lid but was already experiencing intense subduction. Ancient melt inclusions and advanced simulations point to continents ...

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. Subduction and the formation of continents, a ...
In Earth’s early days, more than 4 billion years ago, the surface was a dangerous and unpredictable place. Violent volcanoes, crashing meteorites, and constant tectonic activity repeatedly resurfaced ...
