Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents formed during the Archean time, more than 2.5 billion years ago. Their findings ...

Subduction, a crucial geological process on Earth, may have begun hundreds of millions of years earlier than traditionally believed. This surprising discovery comes from a new study published by ...

When Earth first formed, around 4.5 billion years ago, it was an extremely hot, largely molten planet. As it cooled, heavier ...

The 6,000-year claim faces evidence from several places that have little to do with one another. What those independent ...

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 ...

Geologists took a new look at a sequence of old rocks in southwest Greenland and discovered the earliest example yet of plate tectonics. Until March, when the findings were published in Science, ...
