Subsequent Early Jurassic extension initiated the four main depocentres - the Exmouth, Barrow, Dampier and Beagle Sub-basins.A third extension phase in the Middle Jurassic resulted in the seafloor spreading in the Argo Abyssal Plain to the north and the fourth Tithonian-Valanginian rifting phase culminated in the creation of the Gascoyne-Cuvier abyssal plains to the west and south.Sedimentary rock forms in layers over millions of years.If you look at a cliff made from sedimentary rock, you’ll notice distinct layers that may even be different colors.The Northern Carnarvon Basin encompasses the Exmouth Plateau, Wombat Plateau (on the northern part of the Exmouth Plateau), Investigator Sub-basin, Rankin Platform, Exmouth Sub-basin, Barrow Sub-basin, Dampier Sub-basin, Beagle Sub-basin, Enderby Terrace, Peedamullah Shelf and the Lambert Shelf.The Palaeozoic-Recent Northern Carnarvon Basin, is a large, mainly offshore basin on the northwest shelf of Australia.

The major basin faults trend north or northeast and define a series of structural highs and sub-basins.Triassic to Early Cretaceous deposition is dominantly siliciclastic deltaic to marine, whereas slope and shelfal marls and carbonates dominate the Mid-Cretaceous to Cainozoic section.The carbonate-rich sediments were deposited as a series of northwestward prograding wedges as the region continued to cool and subside.The extensive deep-water (800 - 3000 metres) Exmouth Plateau forms a bathymetric plateau outboard of the main depocentres and developed in response to thermal sag after Valanginian breakup.The main depocentres contain up to 15 km of sedimentary infill.

Scientists can learn exactly how old a rock is by using radiometric dating.
