A tectonic plate that disappeared under North America millions of years ago still peeks out in central California and Mexico, new research finds. The Farallon oceanic plate was once nestled between ...

The driving force behind Yellowstone’s long and explosive volcanic history may not be as deep as once thought. A new study suggests that instead of a plume of hot mantle that extends down to Earth’s ...

Researchers have discovered that the North American continent is slowly losing rock from its underside in a process called "cratonic dripping." This is caused by the remnants of the Farallon Plate, an ...

PROVIDENCE, R.I. [Brown University] — Large chunks of an ancient tectonic plate that slid under North America millions of years ago are still present under parts of central California and Mexico, ...

An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

As the Pacific-Farallon spreading center approached North America, the Farallon plate fragmented into a number of small plates. Some of the microplate fragments ceased subducting before the spreading ...

It’s long been held that North America’s rugged and mountainous west was formed by the movement of the undersea Farallon plate, and that the process was roughly similar to the way groceries pile up at ...

Scientists have discovered tectonic plates hidden deep within the Earth's mantle, which they say rewrite 40 years of history about the evolution of western North America. It has long been thought that ...

PROVIDENCE, R.I., March 18 (UPI) -- A geologic anomaly 60 miles under central California is a remnant of an ancient oceanic plate pushed under North America 100 million years ago, scientists say.

A tectonic plate that disappeared under North America millions of years ago still peeks out in central California and Mexico, new research finds. The Farallon oceanic plate was once nestled between ...

The Isabella anomaly -- the seismic signal of a large mass of cool, dehydrated material about 100 kilometers beneath central California -- is in fact a surviving slab of the Farallon oceanic plate, ...
