  skos:definition "Un craton, appelé aussi aire continentale, est une vaste portion stable du domaine continental, par opposition aux zones instables déformées (les orogènes). Il forme un élément de lithosphère continentale possédant une identité géologique, notamment en termes de nature des roches et de structuration des unités géologiques qui le composent. Un craton est constitué d'une partie crustale de nature continentale, encore appelée croûte cratonique, et d'une partie dite lithosphérique, de nature mantellique. (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Craton\">https://fr.wikipedia.org/wiki/Craton</a>)"@fr, "A craton is an old and stable part of the continental lithosphere, which consists of Earth's two topmost layers, the crust and the uppermost mantle. Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates; the exceptions occur where geologically recent rifting events have separated cratons and created passive margins along their edges. They are characteristically composed of ancient crystalline basement rock, which may be covered by younger sedimentary rock. They have a thick crust and deep lithospheric roots that extend as much as several hundred kilometres into Earth's mantle.
