Before large volumes of continental crust emerged, the team argues, tourmaline formation would have been kinetically difficult. The problem was not just chemistry, but crystal growth. Experimental ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents formed during the Archean time, more than 2.5 billion years ago. Their findings ...

Complex numerical simulations show how slivers of continental crust in the ocean were shaved from continental margins and then transported by transform fault complexes. Once continents have started to ...

How did the continents form? Although to a certain extent this remains an open question, the oceanic plateau of the Kerguelen Islands may well provide part of the answer, according to a ...

The formation of the Earth’s continents occurred during a fiery afterbirth known as the Archean Eon, which stretched from 4 billion to 2.5 billion years ago. It was in this bubbling cauldron of ...

Long before forests, fish, or even single cells, Earth may have needed something as unglamorous as growing continents to make life possible. A study in Terra Nova argues that the planet’s earliest ...
