Minigwal 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Australian Reflectance Grid 25 (ARG25)

The Australian Reflectance Grid (ARG) is a new generation Earth Observation product suite from Geoscience Australia. These standard data products deliver optical surface reflectance data across the Australian landmass and its coastal fringes. This means the products are representative of the optical reflectance properties of the surface, with the variable effects of the atmosphere removed. The resulting datasets are effectively sensor agnostic and future products in this suite are intended to be readily comparable between scales. The first product in this suite is the ARG25, a medium resolution (25 m) grid based on Landsat imagery.

Large-scale exploration targeting for uranium mineral systems within the Eromanga Basin

The Eromanga Basin has the potential to contain significant sandstone-hosted uranium mineralisation. Publicly available geophysical and geochemical datasets have been integrated into a 3D geological map for the Eromanga Basin. Initial uranium mineral system assessment has highlighted two regions of potential exploration significance: the region east of Mt Isa corresponding to the Euroka Arch and the area southwest of Lake Eyre.

Australia's mineral resources and their global status

Australias known resources of a wide range of mineral commodities are considerable in comparison with rates of production. Australia has the worlds largest economic demonstrated resources of bauxite, lead, zinc, silver, ilmenite, rutile, zircon, tantalum, and uranium. In addition, Australia is ranked in the top three countries in the world for economic demonstrated resources of brown coal, copper, cobalt, gold, iron ore, manganese ore, nickel , gem/near-gem and industrial diamond.  Despite a high rate of discovery of significant new mineral deposits, particularly since the 1950s, there is considerable potential for discovery of further mineral deposits in Australia. This is indicated by the abundance of high-quality known resources and the ange of prospective geological settings. Increasingly, future discoveries are likely to be in regions where there has been little exploration to date because of their remoteness or the presence of concealing regolith or sedimentary cover.  The few widely used mineral commodities for which Australia has low levels of demonstrated resources include chromium, platinum group metals, trona, and some components of fertilisers, such as potassium salts, and elemental sulphur.  Given the acceptance of widespread multiple or sequential land use, which accommodates responsible exploration and mining, Australia is very well placed to maintain its position as one of the worlds major suppliers of a wide range of mineral commodities.

The musculature and vascular systems of two species of Cambrian Paterinide (Brachiopoda)

Two species of Paterinide brachiopod preserving details of the musculature and vascular systems have been studied. Their dorsal valves are shown to have a large quadripartite muscle field not unlike that of the articulates with further scars located on the inner face of the apex of the homeochilidium. The dorsal vascular system is possibly saccate (apocopate).  The ventral muscle field has two short subtriangular scars divided from one another by the proximal portions of main vascular canals. The location of other scars is uncertain. The ventral vascular system is probably saccate.

The effects in Western Australia of a major earthquake in Indonesia on 19 August 1977

The Indonesian earthquake of 19 August 1977, with a magnitude (M), 8 was felt in Western Australia up to distances of 2600 km. The maximum ground intensity felt was MM V in northwest towns up to 1100 km from the epicentre. The ground intensity in Perth, 2300 km from the epic entre, was MM III or less. Resonance of multi-storey buildings resulted in an eight-fold amplification of peak ground acceleration on the upper floors. Only minor damage occurred in Perth. Seismic sea waves up to six metres in height were reported several hours after the earthquake at towns along the northwest coast. There were no reports of damage associated with these waves. They arrived along the coast near low tide, otherwise there could have been some flooding. An examination of data from the Sunda arc region, for the period 1900-1977, suggests that about eight earthquakes of magnitude greater than 7.5 could occur in this region every hundred years. Of these, two or three may be felt in Western Australia. The 1977 earthquake was the largest and closest to Western Australia since 1900 and its effects are the maximum likely to be experienced from this region. Consideration should be given to installing accelerographs in selected buildings in Perth.

Murloocoppie Airborne Magnetic Radiometric and DEM Survey, SA, 2016 (P1280), radiometric line data

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Murloocoppie Airborne Magnetic Radiometric and DEM Survey, SA, 2016 (P1280), radiometric line data were acquired in 2017 by the SA Government, and consisted of 109753 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Tectonic and Stratigraphic History of the Perth Basin

The tectono-stratigraphic development of the southwestern corner of Australia is illustrated in a plate reconstructed setting with a series of palaeogeographic maps based on a newly compiled structural elements map and chronostratigraphic section for the Perth Basin.
The area is complicated by at least two periods of extensional faulting, one in the Late Carboniferous Early Permian and a second in the Late Jurassic  Early Cretaceous, separated by sag basin development in the Late Permian to Middle Jurassic. Depositional centres migrated through time and appear to have suffered oblique extension, with the most structuring associated with the Late Jurassic  Early Cretaceous rifting episode. In addition, extensive volcanism leading up to breakup at about 132.5 Ma in the Valanginian has obscured the continent-ocean transition. The resulting basin structure comprises separate NS to NNW/SSE oriented rifted sub-basins, which were rotated and shifted westwards through time. Barremian/Albian oceanic crust then grew in a northwesterly direction in the Perth Abyssal Plain and was followed after ~100 Ma by fast spreading in a NNW direction in the NE Indian Ocean. Strata deposited during the Barremian to Recent sag phase of the Perth Basin are relatively thin and unstructured.
Known or inferred source rocks in this complex basin include gas and minor oil-prone coals in the Lower Permian (Irwin River Formation), Upper Permian (Sue Group), Lower Jurassic (Cattamarra Coal Measures) and Upper Jurassic (Yarragadee Formation). Marine shales, which developed anoxia at flooding surfaces in the Lower Permian (Carynginia Formation, Holmwood Shale) and basal Triassic (Kockatea Shale) became oil-prone source rocks. In addition, there is the possibility of a further speculative oil-prone source in the Bajocian (Cadda Formation) in deep water areas.

Litchfield North, NT, 1981 (P535), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Litchfield North, NT, 1981 survey were acquired in 1981 by the NT Government, and consisted of 36434 line-kilometres of data at 500m line spacing and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Methodologies for multibeam seabed hardness mapping in the Timor Sea - Bathymetry Local Moran I

This dataset contains bathymetry local moran I data from seabed mapping surveys on the Van Diemen Rise in the eastern Joseph Bonaparte Gulf of the Timor Sea. The survey was conducted under a Memorandum of Understanding between Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) in two consecutive years 2009 (GA survey number GA-0322 and AIMS survey number SOL4934) and 2010 (GA survey number GA-0325 and AIMS survey number SOL5117). The surveys obtained detailed geological (sedimentological, geochemical, geophysical) and biological data (macro-benthic and infaunal diversity, community structure) for the banks, channels and plains to investigate relationships between the physical environment and associated biota for biodiversity prediction. The surveys also provide Arafura-Timor Sea, and wider northern Australian marine region context for the benthic biodiversity of the Van Diemen Rise. Four study areas were investigated across the outer to inner shelf. Refer to the GA record 'Methodologies for seabed substrate characterisation using multibeam bathymetry, backscatter, and video data: A case study for the Eastern Joseph Bonaparte Gulf, Northern Australia' for further information on processing techniques applied (GeoCat: 74092; GA Record: 2013/11).
