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. [1] [2]
Newcastle, also commonly referred to as Greater Newcastle is a regional metropolitan area and the second-most-populous district of New South Wales, Australia. It includes the cities of Newcastle and Lake Macquarie and it is the hub of the Lower Hunter region, which includes most parts of the cities of Newcastle, Lake Macquarie, Maitland, Cessnock, and Port Stephens Council. Newcastle is also known by its colloquial nickname, Newy.
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 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 Surat Basin is a geological basin in eastern Australia. It is part of the Great Artesian Basin drainage basin of Australia. The Surat Basin extends across an area of 270,000 square kilometres and the southern third of the basin occupies a large part of northern New South Wales, the remainder is in Queensland. It comprises Jurassic through to Cretaceous aged sediments derived from Triassic and Permian arc rocks of the Hunter-Bowen orogeny. Towns situated above the basin, once dominated by agriculture, are experiencing a boom as mines and infrastructure in the area are expanded.
The Hunter-Bowen Orogeny was a significant arc accretion event in the Permian and Triassic periods affecting approximately 2,500 km of the Australian continental margin.
Cockle Creek railway station is located on the Main Northern line in New South Wales, Australia. It serves the City of Lake Macquarie suburb of Boolaroo. The station is on the eastern side of Cockle Creek and a balloon loop exists west of the creek for the Teralba Colliery.
Speers Point is a suburb of Greater Newcastle, and the location of the council seat of the City of Lake Macquarie local government area in New South Wales, Australia. It is 17 kilometres (10.6 mi) west-southwest of the city of Newcastle on the northern shore of Lake Macquarie, in Cockle and Warners Bays, between the suburbs of Cardiff and Warners Bay.
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.
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.
In lithostratigraphy, coal measures are coal-bearing strata, with the term typically applied to European units of the Upper Carboniferous System.
Belmont Formation may refer to:
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.
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.
Nobbys Tuff is a geologic formation in eastern Australia. Found in Newcastle within the Lachlan Orogen, this stratum is up to 25 metres thick. Formed from volcanic ash in an eruption in the Wuchiapingian age, in the late Permian around 255.02 Ma. This formation includes tuff, tuffaceous sandstone, tuffaceous siltstone, claystone, and chert. Often noticed at Nobbys Head in Newcastle.
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.
The Bundook Beds is a rock formation in the New England Orogen in eastern Australia. The maximum thickness is 2,740 metres, Formed between the Famennian and Frasnian in the late Devonian geological period.
