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

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 ...

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.

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

The way amino acids are synthesized has changed during the history of Earth. The Hadean eon represents the time from which Earth first formed. The subsequent Archean eon (approximately 3,500 ...
