Canning Basin

Entity ID: 22114 Compiled by: Laurie, J.R. and Stewart, A.J. Year: 2002 Status: Defined

Last Revised: 2013

Rank: province Type: sedimentary Subtype: intracratonic Location: WA On-shore and off-shore

Synonyms: NA Symbol: NA

Minimum age: Early Cretaceous Age method: inferred, biostratigraphic correlation

Maximum age: Early Ordovician Age method: inferred, biostratigraphic correlation

Summary: The underexplored, pericratonic Early Ordovician to Early Cretaceous Canning Basin of Western Australia contains over 15 km of marine and nonmarine siliciclastics and marine carbonates. Mory & Hocking (GSWA Record 2011/16, p.6, para 2, last 2 sentences) extended the Basin southwards to include Permian sedimentary rocks 'across a region previously assigned to the Officer Basin...and subsequently the Gunbarrel Basin' (which they redefined as the Cretaceous Bejah Claystone + Samuel Fm only).

Comments: The extra area of Canning Basin added in 2011 (see Summary) is approx 300,000 sq. km. Bejah Claystone and Samuel Fm removed from Canning Basin and assigned to new Gunbarrel Basin in 2011 by GSWA ( R.Hocking email, 20 April 2011). Suitable for CO2 storage.

Overview: The underexplored, pericratonic Early Ordovician to Early Cretaceous Canning Basin of Western Australia occupies about 506,000 (plus 300,000 added in 2011) = 806,000 sq km, of which 730,000 sq km are onshore. It has a maximum sediment thickness of over 15,000 m concentrated in two NW trending depocentres. The northernmost of these is the Fitzroy Trough-Gregory Sub-basin complex, while the southernmost is the Willara Sub-basin-Kidson Sub-basin complex. Deposition in the basin commenced during an Early Ordovician phase of extension and rapid subsidence. Rifting was followed by a prolonged sag stage characterised by widespread evaporitic and playa conditions in the Late Ordovician and Silurian. The second basin phase was initiated by minor folding, regional uplift and erosion in the earliest Devonian, and embraces laterally extensive, aeolian and terrestrial deposits. The third phase incorporates major extension, rifting and rapid subsidence in the mid-Devonian. The sag stage following this extension was interrupted by at least two extensional tectonic pulses marked by influxes of conglomerates along the northern margins of the basin. The fourth basin phase was initiated by mid-Carboniferous compression and inversion of Devonian normal faults. This phase is marked by syntectonic fluvial deposits. The fifth phase is marked by renewed extension and rapid subsidence, coinciding with the onset of glacial conditions in the Early Permian and incorporates a sag stage with widespread transgression following the glaciation. The final tectonic phase was triggered by regional dextral wrench movements in the Late Triassic - Early Jurassic when up to 3km of uplift and erosion occurred, accompanied by extensive molasse deposition. This was followed by deposition of fluvio-deltaic and marine sediments. Only 250 wells have been drilled and 78,000km of seismic shot. Production is currently from Permo-Carboniferous sandstones (Lloyd, Sundown, etc) and Devonian carbonates (Blina) with many shows from Ordovician to Permian. Proven plays include draped bioherms, anticlinal closures and tilted fault blocks. Untested plays include unconformities, fault rollovers, diapirs and stratigraphic traps. Late Carboniferous and Jurassic mafic sills intersected in some wells, both on and offshore. Suitable for CO2 storage (Carbon Storage Taskforce, 2009, Australia's Potential for the Geological Storage of CO2, Dept resources Energy Tourism, Canberra).
