“Our research shows that the chemical signatures we see in continental crust were created in Earth’s earliest period - regardless of how the planet’s surface was behaving,” says Professor Turner.

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

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

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

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

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 ...
