Continental lithosphere is the rigid outer shell of Earth underlying continental regions, comprising continental crust and the uppermost mantle that deform together elastically on short timescales. It is typically 100–250 km thick, much thicker than oceanic lithosphere, and characterized by low-density, silica-rich crust overlying chemically depleted, mechanically strong mantle lithosphere. Its thickness and thermal structure are controlled by tectonic setting, composition, and long-term cooling, influencing isostasy, topography, and intraplate stress. Continental lithosphere plays a central role in plate tectonics, accommodating deformation at plate boundaries, stabilizing cratons, and modulating magmatism, seismicity, and mantle convection patterns.
A new atlas charts the global distribution of unusual, critical-metal-bearing igneous rocks, finding that they often form near the thick and ancient cores of the world's major continents. Researchers from Cambridge's Department ...

When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the familiar geography of today ...
About 56 million years ago, Europe and North America began pulling apart to form what became the ever-expanding North Atlantic Ocean. Vast amounts of molten rock from Earth's mantle reached the ocean floor as the crust stretched ...
