A new geochronology of Mesozoic magmatism along the eastern margin of North America shows that continental breakup involved ...

A hot blob of rock beneath New Hampshire may be helping the Appalachian Mountains stand so tall. The rock mass is slowly on ...

Officially dubbed the Northern Appalachian Anomaly (NAA), this subterranean slimeball sits 125 feet deep underground and ...

Earth’s continents may look fixed on a globe, but they’ve been drifting, splitting and reforming over billions of years – and ...

In continental rifting, there’s a mix of stretching and breaking that reaches deep into the Earth, said geophysicist D. Sarah Stamps. Continental rifting involves the stretching of the ...

A hot blob currently beneath the Appalachians may have peeled off from Greenland around 80 million years ago and moved to ...

Continental rifting involves the stretching of the lithosphere -- the outermost, rigid layer of the Earth. As the lithosphere stretches thin, its shallow regions experience brittle deformation ...

“ These features begin their formation before continental rifting and develop into wide magmatic rift systems capable of isolating slivers of continental crust within the new igneous crust.” ...

Scientists estimate it will take at least 5 to 10 million years for the Afar region to be fully submerged. When that happens, the Gulf of Aden and the Red Sea will flood into the rift, creating a ...

On the other hand, continental subduction/collision in the Paleo-Tethys orogenic system would occur at 250–220 Ma, and continental rifting would occur at 140–120 Ma.
