Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.
A comprehensive examination of the oldest minerals on the planet, microscopic grains of zircon more resistant than diamond, has provided the strongest chemical evidence to date that processes of ...
During the Hadean eon, Earth was a world of constant impacts, molten rock, and a toxic atmosphere. The surface was repeatedly melted by asteroid strikes while intense heat escaped from the planet’s ...
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 ...

An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state. This ...
