Earth's continents are slowly moving across the planet's surface due to plate tectonics, culminating in regions of crustal ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

For geologists, a continent is a large area of thick continental crust composed of granite or similar igneous rocks, forming the continental base, in combination with metamorphic rocks ...

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's continental crust, cratons have remained largely unchanged for billions of years.

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...

The evolution and differentiation of the continental crust pose fundamental questions that are being addressed by new research concerning melting, melt extraction and transport through the crust, and ...
