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

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

Even the oldest and most stable of lithospheric structures can’t withstand geologic machinations deep within the Earth.

With a computer rendering, he helped scientists understand that the earth, with its shifting tectonic plates, is “an ...

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

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

The oldest crust on Earth, known to be unchanging, is actually being altered in real time. The North American continent is ...
