The Perth Basin is a thick, elongated sedimentary basin in Western Australia. It lies beneath the Swan Coastal Plain west of the Darling Scarp, representing the western limit of the much older Yilgarn Craton, and extends further west offshore. Cities and towns including Perth, Busselton, Bunbury, Mandurah and Geraldton are built over the Perth ...
The Darling Scarp originated as the local expression, in the Perth area, of the extensive Darling Fault, a major and ancient geological discontinuity separating the Archaean Yilgarn Craton in the east from the younger Pinjarra Orogen and overlying Phanerozoic Perth Basin to the west.

Basic geological regions of Australia, by age. The large brown region in the lower left of the continent constitutes the Yilgarn Craton. The Yilgarn Craton is a large craton that constitutes a major part of the Western Australian land mass.
The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean.The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia regions.
The Australian plate is a major tectonic plate in the eastern and, largely, southern hemispheres. Originally a part of the ancient continent of Gondwana , Australia remained connected to India and Antarctica until approximately 100 million years ago when India broke away and began moving north.
The quantity of Perth basin oil production rose substantially in 2001 when the Cliff Head field (10 km off the coast near Dongara in 15 m of water) was brought into production., [31] about 320 km north of Perth. The refinery mostly produced petrol and diesel, along with jet fuel, bitumen and liquid petroleum gas (LPG). [2]
They are part of the Perth Basin, and are a sequence of non-marine, probably fluvial sandstones, shales and silts including bituminous coal, and are up to 300 m thick. The Cattamarra Coal Measures conformably overly the Eneabba Formation. [2] The Cattamarra Coal Measures constitute an unconventional tight gas reservoir. [3]
