The heat transport and lithospheric dynamics of early Earth are currently explained by plate tectonic and vertical tectonic models, but these do not offer a global synthesis consistent with the ...

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 ...

Temporal evolution for the viscosity (upper row) and compositional (lower row) field of the 3D reference case showing LLSVP-sourced plume-induced subduction initiation. (a–) Model snapshots at 0 Myr ...

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 ...

image: This shows the mechanisms for the recent Virginia and Oklahoma earthquakes that occurred within the North American plate, and the 2010 Haiti Earthquake that occurred on the plate boundary ...

Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

A new study makes the case that the solar system’s hellish second planet once may have had plate tectonics that could have made it more hospitable to life. By Kenneth Chang Venus today is not like ...

It is common knowledge that the Earth's rigid upper layer called lithosphere is composed of moving plates. But just what mechanism first set plate tectonics into motion still remains a mystery.

But Earth's grinding plates, the source of its deadly tectonics, are actually one of the key ingredients that make it only planet with life in the solar system (found so far). Now, a new model seeks ...

Take a hike along the mountain belts scattered around the Adriatic Sea, and you may find yourself clambering across the crumpled leftovers of a long-lost continent. This rocky jumble represents the ...
