Research news on continental lithosphere

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.

How our planet's history was shaped when the Earth moved

The history of Earth is written on the great tablets of tectonic plates. The motions of plates shaped land masses, formed oceans, and created the varied climates and habitats that set the stage for evolution and the diversity ...

When continents try, and fail, to break apart

Great things can come from failure when it comes to geology. The Midcontinent rift formed about 1.1 billion years ago and runs smack in the middle of the United States at the Great Lakes. The rift failed to completely rupture, ...
