Collie Sub-basin

The Collie Sub-basin is a pocket of Permian sedimentary rocks with an area of 225 kmĀ², enclosed within much older Archean rocks of the Yilgarn Craton, near the town of Collie in southwestern Western Australia.,[1][2] Once considered a unique basin, this area, along with the smaller Wilga and Boyup Sub-basins to the south, are now classified as outliers of the Perth Basin, separated from the main area by ancient earth movements and erosion. The Collie Sub-basin contains significant coal reserves, currently being mined mainly for electricity generation.[3]
