Eromanga Basin
The Eromanga Basin is a large Mesozoic sedimentary basin in central and northern Australia. It covers parts of Queensland, the Northern Territory, South Australia, and New South Wales, and is a major component of the Great Artesian Basin. The Eromanga Basin covers 1,000,000 km2 and overlaps part of the Cooper Basin. The basin is made of sandstone, siltstone, mudstone, coal, shale, and red beds. Two impact structures have been identified in the basin, Mount Toondina crater and Tookoonooka crater. In Queensland and South Australia the Eromanga Basin has been explored and developed for petroleum production. Commercial quantities of gas were first discovered in 1976 and oil in 1978. The basin contains Australia's largest onshore oilfield, the Jackson oil field. Moomba is the centre of South Australia's oil production in the basin. The geology of the portion of the Eromanga Basin in New South Wales remains under-explored. During the middle of the Cretaceous period much of inlan ...

Mesozoic
The Mesozoic Era is the Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of Gymnosperm, gymnosperms such as cycads, ginkgoaceae and Araucariaceae, araucarian conifers; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackson Oil Field
Jackson oil field is the largest onshore oil field in Australia. It is in Durham, Shire of Bulloo in southwestern Queensland, approximately west of Thargomindah. Jackson oil plant is an oil processing facility near the field. It processes oil from several oil fields in the Eromanga Basin and Cooper Basin The Cooper Basin is a Permian-Triassic sedimentary geological basin in Australia. The intracratonic rift basin is located mainly in the southwestern part of Queensland and extends into northeastern South Australia. It is named after the Coop ...s. The field was discovered in 1981 and contains 350 million barrels of oil, of which just under one third is recoverable. Peak production occurred in 2000.

Geology Of Queensland
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 Peninsula, Cape York regions. The Thomson Orogen occurs in the central and southern parts of Queensland, but is mostly covered by younger basins. The North Queensland Orogen is along the coast from Charters Towers to Princess Charlotte Bay. The Bowen Gunndedah Sydney basin can be considered as one system that extends into Queensland. The New England Orogen is on the coastal parts from the border with New South Wales north to Ayr, Queensland, Ayr.

Energy Policy Of Australia
Energy policy in Australia is managed by the states and territories as well as at the federal level. The federal government sets the broad energy framework, including national targets for renewable energy, emissions reduction, and energy security. It is responsible for implementing national energy policies, overseeing the operation of the National Electricity Market, national electricity market (NEM), regulating fossil fuel industries, and managing energy subsidies and tax incentives. Additionally, the federal government plays a key role in coordinating national energy infrastructure projects, including large-scale renewable energy initiatives, and sets legislation that governs energy efficiency standards, and environmental protections. State and territory governments in Australia are responsible for implementing energy policies at the local level, including managing energy infrastructure, overseeing electricity networks, and setting state-specific renewable energy targets.

Albian
The Albian is both an age (geology), age of the geologic timescale and a stage (stratigraphy), stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early Cretaceous, Early/Lower Cretaceous epoch (geology), Epoch/series (stratigraphy), Series. Its approximate time range is 113.0 ± 1.0 annum, Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for Aube (river), River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan ''Hedbergellidae, Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age (geology), age in the geologic timescale or a stage (stratigraphy), stage in the stratigraphic column. It is a subdivision of the Early Cretaceous, Early or Lower Cretaceous epoch (geology), Epoch or series (stratigraphy), Series and encompasses the time from 121.4 ± 1.0 annum, Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western Europe, Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 annum, Ma and lasted approximately 1 to 1.3 million years, being marked by enhanced silicate weathering, as well as ocean acidification. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma. Stratigraphic definitions The Aptian was named after the small city o ...

Ichthyosaur
Ichthyosauria is an order of large extinct marine reptiles sometimes referred to as "ichthyosaurs", although the term is also used for wider clades in which the order resides. Ichthyosaurians thrived during much of the Mesozoic era; based on fossil evidence, they first appeared around 250 million years ago ( Ma) and at least one species survived until about 90 million years ago, into the Late Cretaceous. During the Early Triassic epoch, ichthyosaurs and other ichthyosauromorphs evolved from a group of unidentified land reptiles that returned to the sea, in a development similar to how the mammalian land-dwelling ancestors of modern-day dolphins and whales returned to the sea millions of years later, which they gradually came to resemble in a case of convergent evolution. Ichthyosaurians were particularly abundant in the Late Triassic and Early Jurassic periods, until they were replaced as the top aquatic predators by another marine reptilian group, the Plesiosauria, i ...

Plesiosauria
The Plesiosauria or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous '' Plesiosaurus'', was named in 1821. Since then, more than a hundred valid species have been described. In the early twenty-first century, the number of discoveries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eromanga Sea
The Eromanga Sea was an inland sea across the Australian continent that formed in the Early Cretaceous. The sea extended from the Eromanga Basin northward to the Carpentarian Basin. Its southern extents comprised lagoons and rivers, and to the east it reached Surat Basin, a bay. The sea covered large parts of what is now Queensland and Central Australia at least four times during the early Cretaceous. The present-day Winton Formation represents remnants of the river plains that filled the basin left by the Eromanga Sea. The formation is a major source of dinosaur fossils. Opals The Great Artesian Basin (GAB) was flooded by the Eromanga Sea and filled with volcaniclastic sediments eroded from the Cordillera's volcanic arc. A theory was proposed explaining the abundance of opals in GAB. It was suggested that the Eromanga Sea was shallow, cold, muddy, and stagnant, which have led to little amount of carbonate A carbonate is a salt of carbonic acid, (), characterized by the ...
