As continents continue moving, study suggests effects on biodiversity

Continental drift and plate tectonics—the notion that large chunks of Earth's crust slowly but inexorably shift positions—was proposed in 1912 but not accepted until...

Continental crust thanks to the right mixture

For the first time, ETH scientists have successfully recreated the formation of continental crust in the Archean using a computer simulation. The model helps...

A new interpretation of petrogenesis of Earth’s early continental crust

The Earth's continental crust was mainly formed in the Archean period, ~2.5 to 4.0 billion years ago, and is chiefly composed of tonalite, trondhjemite...
