The research revealed that Earth’s first crust, formed about 4.5 billion years ago, likely had chemical features similar to those of today’s continental crust. The finding challenged widely held ...

Earth’s earliest crust, formed over 4.5 billion years ago, has long been thought to have lacked the complex chemical features ...

New research suggests that Earth's first crust, formed over 4.5 billion years ago, already carried the chemical traits we ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs ...

It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in ...

“This argument suggests that helium-3 was incorporated into the iron-rich core during Earth’s formation, some of which leaked from the core to the mantle,” Hirose explains. It could be that the ...

This primordial element was already known to exist inside Earth ... with the solid phase of the core," Olson said. "But because the core almost certainly formed in a liquid state, there is ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially ... that surrounds the iron core of rocky planets. The structure and dynamics ...
