Victoria is an Australian state, situated at the southern end of the Great Dividing Range. The Great Dividing Range stretches along the east coast of the continent and terminates near the Victorian city of Ballarat west of the capital Melbourne, though the nearby Grampians may be considered to be the final part of the range. The highest mountains in Victoria are the Victorian Alps, located in the northeast of the state.
The Sydney Basin is an interim Australian bioregion and is both a structural entity and a depositional area, now preserved on the east coast of New South Wales, Australia and with some of its eastern side now subsided beneath the Tasman Sea. The basin is named for the city of Sydney, on which it is centred.
The geology of the Australian Capital Territory includes rocks dating from the Ordovician around 480 million years ago, whilst most rocks are from the Silurian. During the Ordovician period the region—along with most of eastern Australia—was part of the ocean floor. The area contains the Pittman Formation consisting largely of quartz-rich sandstone, siltstone and shale; the Adaminaby Beds and the Acton Shale.
The geology of Australia includes virtually all known rock types, spanning a geological time period of over 3.8 billion years, including some of the oldest rocks on earth. Australia is a continent situated on the Indo-Australian Plate.
The Hill is an inner city, residential suburb of Newcastle, in the Hunter Region of New South Wales, Australia, located immediately south of Newcastle's central business district. The Hill is filled with historic Victorian terraces and is the site of a historic convict prison block. As of January 2021, the average house price in The Hill was A$1.92m.
Nobbys Head is a headland located on the southern entrance to Newcastle Harbour, New South Wales, Australia. The headland is situated above the Hunter River and the Tasman Sea of the South Pacific Ocean.
The Lachlan Fold Belt (LFB) or Lachlan Orogen is a geological subdivision of the east part of Australia. It is a zone of folded and faulted rocks of similar age. It dominates New South Wales and Victoria, also extending into Tasmania, the Australian Capital Territory and Queensland. It was formed in the Middle Paleozoic from 450 to 340 Mya. It was earlier known as Lachlan Geosyncline. It covers an area of 200,000 km2.
Nobbys Head Light is an active lighthouse on Nobbys Head, a headland on the south side of the entrance to Newcastle Harbour, New South Wales, Australia. An image of the lighthouse is included in the coat of arms of the City of Newcastle.
Geologically the Australian state of New South Wales consists of seven main regions: Lachlan Fold Belt, the Hunter-Bowen Orogeny or New England Orogen (NEO), the Delamerian Orogeny, the Clarence Moreton Basin, the Great Artesian Basin, the Sydney Basin, and the Murray Basin.
The geology of Queensland can be subdivided into several regions with different histories. Along the east coast is a complex of Palaezoic to Cainozoic rocks while much of the rest of the state is covered by Cretaceous and Cainozoic rocks. A Precambrian basement is found in the north west and Cape York regions. The Thomson Orogen occurs in the central and southern parts of Queensland, but is mostly covered by younger basins.
The Clarence Moreton Basin is a Mesozoic sedimentary basin on the easternmost part of the Australian continent. It is located in the far north east of the state of New South Wales around Lismore and Grafton and in the south east corner of Queensland. It is the part of the Great Artesian Basin that extends to the east coast in Australia's central eastern lowlands.
Nobby is a diminutive form of the name Norbert or a nickname.
The Whitehill Formation, alternatively written as White Hill Formation and formerly known as White Band or Whitehill or White Hill Member, is a regional Early Permian geologic formation belonging to the Ecca Group in the southeastern ǁKaras Region of southeastern Namibia and Eastern, Northern and Western Cape provinces of South Africa.
Munmorah Conglomerate is a geologic formation in the Sydney Basin in eastern Australia. This stratum is up to 140 metres thick. Formed in the early-Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes medium to coarse-grained sandstone and conglomerate. With minor amounts of siltstone and claystone. Below the Munmorah Conglomerates are Newcastle Coal Measures, originating from the Permian.
The Terrigal Formation is a geologic formation in the Sydney Basin in eastern Australia. Commonly seen in the Central Coast region, this stratum is up to 330 metres thick. Formed in the early to mid Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes interbedded fine to medium-grained sandstone and siltstone, with minor deposits of claystone. Hawkesbury Sandstone occasionally overlies the Terrigal Formation. Numerous fossils are known from this area, including the temnospondyl amphibian Arenaerpeton supinatus.
The Allyn River Member is a geologic formation in the New England Orogen in eastern Australia.
The Minyon Falls Rhyolite Member is a geologic formation in the far north east of New South Wales, Australia. This formation is up to 500 metres thick. Formed from a volcanic lava flow some 20 million years ago in the Cenozoic, it is part of the Nimbin Rhyolite group of the Lamington Volcanics. Constituents include porphyritic and non porphyritic rhyolite, obsidian, pitchstone, tuff, and agglomerate. It may be viewed at Minyon Falls.
Newcastle Coal Measures is a major geologic formation in eastern Australia. Found in the Sydney Basin and Lachlan Orogen, this stratum is up to 1200 metres thick, consisting of dozens of different sub types. Formed between the Changhsingian and Wuchiapingian ages, around 256 to 252 Ma in the Permian. This formation includes coal seams, tuffaceous claystone, siltstone, sandstone, and conglomerate. Medium to coarse-grained sandstone is present, often noticed by bathers at the Bogey Hole. Volcanic constituents of the Newcastle Coal Measures include Nobbys Head, which features Nobbys Tuff.
Reids Mistake Formation is a geologic formation in the Sydney Basin in eastern Australia. It may be seen at the Swansea Headland Petrified Forest, near Swansea, New South Wales. Formed in the late Permian, it is part of the Boolaroo Subgroup of the Newcastle Coal Measures.
Boolaroo Subgroup is a geologic formation in the Lachlan Orogen in eastern Australia in the Hunter Region. Formed in the late Permian, it is part of the Newcastle Coal Measures. This formation includes sandstone, conglomerate, tuff, and black coal. Belmont Conglomerate Member, part of the Boolaroo Subgroup can be seen at Caves Beach, New South Wales.
