The Wollemi National Park is a protected national park and wilderness area that is located in the Central West and Hunter region of New South Wales, in eastern Australia. The 501,703-hectare (1,239,740-acre) park, the second largest national park in New South Wales, contains the 361,113-hectare (892,330-acre) Wollemi Wilderness – the largest such wilderness area in Australia – and is situated approximately 130 kilometres (81 mi) northwest of Sydney.
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.
Barrenjoey is a locality in the suburb of Palm Beach, at the most northern tip of Pittwater. The headland is made up primarily of sandstones of the Newport Formation, the top third is a cap of Hawkesbury sandstone. Around 10,000 years ago the headland was cut off from the mainland due to the rising sea level; subsequent buildup of a sand spit or tombolo reconnected the island to the mainland. It is the location of the Barrenjoey Head Lighthouse, a lighthouse that was first lit in 1881. In 1995 Barrenjoey was gazetted into Ku-ring-gai Chase National Park.
Munmorah Power Station is a demolished coal-fired power station with four 350 MW English Electric steam driven turbo-alternators for a combined capacity of 1,400 MW. The station was located near Doyalson, on the shores of Lake Munmorah, New South Wales, Australia and was owned and operated by Delta Electricity, a company owned by the New South Wales Government.
Lake Munmorah or Munmorah Lake, a lagoon that is part of the Tuggerah Lakes, is located within the Central Coast Council local government area in the Central Coast region of New South Wales, Australia. The lake is located near the settlement of Lake Munmorah and is situated about 110 kilometres (68 mi) north of Sydney.
The Wianamatta Group is a geological feature of the Sydney Basin, New South Wales, Australia that directly overlies the older Hawkesbury sandstone and generally comprise fine grained sedimentary rocks such as shales and laminites as well as less common sandstone units.
The Narrabeen group of sedimentary rocks occurs in the Sydney Basin in eastern Australia. This series of rocks was formed in the Triassic Period.
The Mittagong Formation is a sedimentary rock unit in the Sydney Basin in eastern Australia.
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 Illawarra Coal Measures is a group of sedimentary rocks occurring in the Sydney Basin in eastern Australia. This stratum is up to 150 metres thick. Formed in the Late Permian, it comprises shale, quartz-lithic sandstone, conglomerate rocks, and chert, with sporadically carbonaceous mudstone, coal and seams of torbanite. Coal mining of these measures remains a significant commercial enterprise to the present day. One of the abandoned coal mines in the Blue Mountains is now a tourist attraction.
Bald Hill Claystone is a sedimentary rock found in the Sydney Basin in eastern Australia. It is part of the Clifton sub-group of the Narrabeen Group of sedimentary rocks. It was formed by weathering of the Gerringong Volcanics in the early Triassic. Named after Bald Hill, in the northern Illawarra, where it is 15 metres thick. The claystone is easily noticed at Long Reef, where it is 18 metres thick.
The Newport Formation is a geologic formation outcropping in the Sydney Basin in eastern Australia. This stratum is up to 49 metres thick. Formed in the mid-Triassic, it is part of the Narrabeen Group of sedimentary rocks.
The Garie Formation is a narrow band of sedimentary rocks occurring in the Sydney Basin in eastern Australia. This stratum is up to 8 metres thick, situated below the sandstones of the Newport Formation. Formed in the mid-Triassic, it is part of the Narrabeen Group of sedimentary rocks. Garie formation consists of layers of clay pellet sandstone, dark lithic particles, spotted volcanic deposits and chocolate coloured claystone bands.
Bulgo Sandstone is a sedimentary rock occurring in the Sydney Basin in eastern Australia. This stratum is up to 100 metres thick, formed in the early Triassic (Olenekian). A component of the Narrabeen Group of sedimentary rocks. It consists of layers of fine to medium-grained quartz-lithic sandstone, with lenticular shale interbeds.
Mount York Claystone is a narrow band of sedimentary rocks occurring in the Sydney Basin in eastern Australia. This stratum is up to 13 metres thick. Mount York Claystone consists of red brown claystones, of fine‐grained and coarsely oolitic, kaolinite clayrocks.
Banks Wall Sandstone is a type of sedimentary rock occurring in the Sydney Basin in eastern Australia. This stratum is up to 115 metres thick. Often seen in the Blue Mountains, such as at the Three Sisters at Katoomba.
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.
Scarborough Sandstone is a geologic formation in the Sydney Basin in eastern Australia. Commonly seen in the Illawarra region, this stratum is up to 26 metres thick. Formed in the early Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes quartz-lithic sandstone, sometimes with pebbles.
Stanwell Park Claystone is a geologic formation in the Sydney Basin in eastern Australia. Commonly seen in the Illawarra region, this stratum is up to 79 metres thick. Formed in the early Triassic, it is part of the Narrabeen Group of sedimentary rocks.This formation includes red, green and grey shale with quartz-lithic sandstone.
Wombarra Claystone is a geologic formation in the Sydney Basin in eastern Australia. Commonly seen in the Illawarra region, this stratum is up to 30 metres thick. Formed in the late Permian to the early Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes grey shale, and minor quartz-lithic sandstone.
