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, ...

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 ...

The Earth’s lithosphere is continuously reshaped by the relative motions of rigid and deformable tectonic plates driven by mantle convection, slab pull and ridge push forces. Over hundreds of millions ...

A geologic map of the Pilbara Craton in Western Australia. The rocks exposed here range from 2.5 to 3.5 billion years ago, offering a uniquely well-preserved window into Earth's deep past. The authors ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

A study led by geoscientists at the University of Sydney has revealed why some ancient continental edges became fertile sites ...

Watch the Earth's tectonic plates grow, shrink, and jostle for position in this new model of the last billion years on the ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. A new study, using a combination of old models, new geophysical ...

The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...
