Australia: The Land Where Time Began
The Canning Basin covers an area of 595,000 km2 in north-western Western Australia. It was uplifted at the end of the Cretaceous, dev eloping a river system of its own, that drained to the northwest.
In the Gregory sub-basin, the deepest depocentre, there is an accumulation of sediment about 18 km. To the north, the onshore section of the basin is bounded by the Kimberley Block, to the south by the Pilbara and Musgrave Blocks. To the east it is separated from the adjacent Amadeus Basin by an arch of Upper Proterozoic Sediments To the south-east it is separated from another adjacent basin, the Officer Basin, by the Warri Arch, a belt of shallow basement rocks.
About 1/3 of the basin lies offshore, up to 1000 m below the surface. The Loveque Shelf separates it from the Browse Basin to the north, and in the south from the Carnarvon Basin by the Pilbara Shelf, the North Turtle Arch and the fault north of the arch.
