A Chemical Fingerprint in Ancient Rocks Suggests Plate Tectonics Began 2.5 Billion Years Ago
Nautilus · By Janne Liebmann ·
The Brief
- A Nautilus article reports that a chemical fingerprint in ancient rocks suggests plate tectonics began about 2.5 billion years ago.
- The source describes a time when Earth did not yet have plate tectonics.
- The available source is a short excerpt, so the study's methods and details could not be verified.
Why it matters
If the timing of plate tectonics' start is confirmed, it would shape how scientists understand the early evolution of Earth's crust, climate and surface environments.
Who’s affected
- geologists and Earth scientists
