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

Scientists have discovered that a portion of the North American craton is slowly dripping into Earth's mantle, challenging ...

Scientists discovered Earth's first crust had continental chemical signatures. This challenges beliefs about when these ...

Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in continents.

A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today’s continental crust. This suggests the ...

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research ...

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

It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in continents. The research shows this fingerprint existed in Earth’s first ...

A recent study challenges previous geological assumptions, revealing that Earth's initial protocrust closely resembled the ...

This week, researchers reported on nine rivers and lakes in the Americas that defy hydrologic expectations. Geologists report ...
