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 ...
Rifting of Australia from India and Africa began in the Permian, resulting in the production of a rift basin and half-grabens of the basal portions of the long-lived Perth Basin. Petroleum was formed in the Swan Coastal Plain and Pilbara during this rifting, presumably in a rift valley lake where the bottom was deoxygenated (akin to Africa's ...
The Yilgarn Craton appears to have been assembled between ~2.94 and 2.63 Ga by the accretion of a multitude of formerly present blocks or terranes of existing continental crust, most of which formed between 3.2 Ga and 2.8 Ga.
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]
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.
An Aurora, Colorado judge granted the 'emergency closure' of The Edge at Lowry Apartments after multiple arrests and rumored gang activity.
The Diamantina fracture zone was first detected by RV Vema and RV Argo in 1960. It is named after HMAS Diamantina (K377), which conducted further exploration in 1961.. Professor Alan Jamieson from The University of Western Australia led a scientific expedition to the eastern margin of the DFZ, which enters the southwest corner of the Australian exclusive economic zo
