Bookmark or Share- Deep continental roots and cratons | NatureHere, we review some physical and chemical properties of the deep lithospheric roots beneath continents and examine their integral role in forming the oldest parts of the continents: the cratons....
- Craton | Structure, Shield, Platform | Britannicacraton, the stable interior portion of a continent characteristically composed of ancient crystalline basement rock. The term craton is used to distinguish such regions from mobile geosynclinal troughs, which are linear belts of sediment accumulations subject to subsidence (i.e., downwarping).
- Cratons – old and strong - Metageologist - All-geoCratons are pieces of continents that have been stable for a over a billion years. As earth's plates drift along, mountains periodically rise and fall, plate boundaries appear and disappear. But cratons are like great-grandmothers at family gatherings, while younger crust moves excitedly around them, they sit quietly, occasionally remarking on ...
- What is a craton? How many are there? How do they relate ... - NASA/ADSA craton is a large, coherent domain of Earth's continental crust that has attained and maintained long-term stability, having undergone little internal deformation, except perhaps near its margins due to interaction with neighbouring terranes.
- Creating Continents: Archean Cratons Tell the StoryCratons preserve an important record of crust formation and growth, provide the oldest record of processes that led to a differentiated Earth, and enable critical geologic observations for testing theoretical models of early Earth evolution (e.g., Korenaga, 2021).
