[[File:North america basement rocks.png|270px|right|thumb|Palaeomap of North American and Scandinavian cratons, basement rocks, and orogenic belts. Slave Craton is in the top left in red and bright green]] The '''Slave Craton''' is an [[Archaean]] [[craton]] in the north-western [[Canadian Shield]], in [[Northwest Territories]] and [[Nunavut]]. It has some of the oldest rocks on Earth.<ref> Bleeker W; Davis B; Ketchum J; Stern R; Sircombe K; Waldron J. 2004. The Slave Craton from on top: the crustal view. ''Geological Survey of Canada''.</ref> It has ~2.73–2.63&nbsp;Ga (billion years-old) [[greenstone belt|greenstones]] and [[turbidite]] sequences. These are the geologic deposits of a [[turbidity]] current. This type of gravity flow put vast amounts of [[Clastic rock|clastic]] [[sediment]] into the deep ocean. Large parts of the craton are underlain by even older [[gneiss]] and [[granitoid]] units. == References == {{reflist}} [[Category:Geology of Canada]] [[Category:Geological formations]]
