Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.
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 ...
Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape.
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 ...

Hadean zircons reveal crust recycling and continent formation more than 4 billion years ago
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 ...
Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name "Hadean" comes from the Greek god of the underworld, reflecting the extreme heat that likely ...
The ancient history of Earth has always been hard to read. Most of the planet’s earliest crust has been lost, buried, or melted by geologic processes over billions of years. The rare remnants that ...
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 ...
New ANU research is set to radically overturn the conventional wisdom that early Earth was a hellish planet barren of continents. An international research team led by Professor Mark Harrison of the ...
