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, ...

Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...

Add Yahoo as a preferred source to see more of our stories on Google. The researchers studied the East Pilbara Craton formation in Western Australia’s Pilbara region, seen here. - Roger Norman/Alamy ...

For the first time in history, scientists have observed the rupture of a tectonic plate in a subduction zone in real time. The study, published in the scientific journal Science Advances, was ...

Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and subducting at more than 10 centimeters per year remain sufficiently cold to ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...

This groundbreaking research offers a comprehensive reconstruction of Earth’s tectonic evolution from 1.8 Ga to the present, bridging critical gaps in pre-Pangean plate dynamics. By merging three ...

Made me recall the Biosphere II experiment in Arizona late 80s/early90s. The O2 levels had fallen to below 14% and yet CO2 had not significantly increased. The question was, were was the oxygen going ...
