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 ...

To understand the geologic processes roiling beneath the Earth’s crust, it helps to have samples of what exactly is going on down there. For more than 60 years, scientists have been trying to retrieve ...

Earth's deep mantle stored enough water in rocks to equal one ocean during our planet's early molten days, helping explain ...

This is a preview. Log in through your library . Abstract The C-region of the upper mantle has two transition regions 75 to 90 kilometers thick. In western North America these start at depths of 365 ...

Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

The Indian-Eurasian continental collision is one of the most spectacular geological events since the Cenozoic, forming the Tibetan Plateau, known as the "roof of the world". The non-uniform ...

When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks ...
