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 ...

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 ...

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

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 ...

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

“ 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.” ...

A Geological Laboratory The Afar region is home to the East African Rift Valley, a massive crack in the Earth’s surface that stretches through Ethiopia and Kenya. In 2005, a 35-mile-long fissure ...

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.
