Archaean cratons are composite fragments of the early Earth's continental crust. During their evolution, cratons were stabilised by the process of cratonisation, typified by craton-wide magmatism. However, the nature of cratonisation remains ambiguous. Here, it is shown that formation of the Yilgarn Craton of Western Australia involved three magmatic stages and a secula revolution in magma compositions and tectonic settings. A model for cratonisation is invoked involving lithospheric thickening at c. 2740 Ma, followed by intraplate anatexis of the lower crust at c. 2680 Ma, then middle crust at c. 2630 Ma, cratonising the lithosphere and forming an Archaean continent.
