Researchers uncover source rocks of the first real continents

Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. ...

Superdeep diamonds provide a window on supercontinent growth

Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research from a team of scientists led by Suzette Timmerman—formerly of the University ...

Ancient diamonds shine light on the evolution of Earth

The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth.

Study presents new clues about the rise of Earth's continents

Continents are part of what makes Earth uniquely habitable for life among the planets of the solar system, yet surprisingly little is understood about what gave rise to these huge pieces of the planet's crust and their special ...

Seeing through sediment reveals Red Sea tectonics
