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, ...
A study led by geoscientists at the University of Sydney has revealed why some ancient continental edges became fertile sites ...
An exceptionally well-preserved skull from a fish which lived 384–382 million years ago helps explain how plate tectonics played a key role in the evolution of ancient bony fish which eventually led ...
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 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 ...
Rifted margins mark the transition from continental to oceanic realms and preserve a rich archive of lithospheric deformation, magmatism and sedimentary processes. Initiated by plate divergence, ...
Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

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 ...
