#Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny #mineral #crystals called #zircons to study plate #tectonics billions of years ago. The research sheds light on the conditions that existed in early #Earth, revealing a complex interplay between Earth’s crust, core, and the emergence of #life.
