3.1-Billion-Year-Old Rocks Rewrite the History of Earth’s Early Tectonics

Earth may have been recycling surface water through its deep interior more than three billion years ago. In the Pilbara region of Western Australia, volcanic rocks more than three billion years old preserve traces of a journey once considered unlikely. Their chemistry suggests that water from Earth’s surface had already traveled deep into the planet, […]
