GSWA Broome North Canning 1 ppm Thorium Grid Geodetic

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 radiometric thorium grid has a cell size of 0.00083 degrees (approximately 90m) and shows thorium element concentration of the Broome, WA, 2009 (North Canning 1) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2009 by the WA Government, and consisted of 76474 line-kilometres of data at 400m line spacing and 60m terrain clearance.

The 2018 National Seismic Hazard Assessment (NSHA) - Derived Geo-spatial Product

As part of the 2018 National Seismic Hazard Assessment (NSHA), we compiled the geographic information system (GIS) dataset to enable end-users to view and interrogate the NSHA18 outputs on a spatially enabled platform. It is intended to ensure the NSHA18 outputs are openly available, discoverable and accessible to both internal and external users. 

This geospatial product is derived from the dataset generated through the development of the NSHA18 and contains uniform probability hazard maps for a 10% and 2% chance of exceedance in 50 years.  These maps are calculated for peak ground acceleration (PGA) and a range of response spectral periods, Sa(T), for T = 0.1, 0.2, 0.3, 0.5, 1.0, 2.0 and 4.0 s.  Additionally, hazard curves for each ground-motion intensity measure as well as uniform hazard spectra at the nominated exceedance probabilities are calculated for key localities.

South Australian Gulf and Yorke Cenozoic Basins hydrogeological inventory

This South Australian Gulf and Yorke Cenozoic Basins dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.
The South Australian Gulf and Yorke Cenozoic basins consist of eleven separate basins with similar sediments. These relatively small to moderate-sized basins overlies older rocks from the Permian, Cambrian, or Precambrian periods and are often bounded by north-trending faults or basement highs. The largest basins, Torrens, Pirie, and Saint Vincent, share boundaries. 
The Torrens and Pirie basins are fault-bounded structural depressions linked to the Torrens Hinge Zone, while the Saint Vincent basin is a fault-bounded intra-cratonic graben. Smaller isolated basins include Carribie and Para Wurlie near the Yorke Peninsula, and Willochra and Walloway in the southern Flinders Ranges. The Barossa Basin, Hindmarsh Tiers, Myponga, and Meadows basins are in the Adelaide region. These basins resulted from tectonic movements during the Eocene Australian-Antarctic separation, with many forming in the late Oligocene. Sediment deposition occurred during the Oligocene to Holocene, with various environments influenced by marine transgressions and regressions. 
The well-studied Saint Vincent Basin contains diverse sediments deposited in fluvial, alluvial, deltaic, swamp, marine, littoral, beach, and colluvial settings, with over 30 major shoreline migrations. Eocene deposition formed fluvio-deltaic lignite and sand deposits, before transitioning to deeper marine settings. The Oligocene and Miocene saw limestone, calcarenite, and clay deposition, overlain by Pliocene marine sands and limestones. The uppermost sequences include interbedded Pliocene to Pleistocene limestone, sand, gravel, and clay, as well as Pleistocene clay with minor sand lenses, and Holocene to modern coastal deposits. The sediment thickness varies from less than 50 m to approximately 600 m, with the Saint Vincent Basin having the most substantial infill. Some basins were previously connected to the Saint Vincent Basin's marine depositional systems but later separated due to tectonic movements.

Timing of Mesoproterozoic tectonic activity in the northwestern Gawler Craton constrained by 40Ar/39Ar geochronology

An array of northeast-trending shear zones in the north-west Gawler Craton of South Australia has been implicated in widely disparate Proterozoic continental reconstructions. These shear zones are interpreted to have formed in response to sinistral transpression, and dissect the north-west Gawler Craton into several geological domains, each with contrasting metamorphic histories. New 40Ar/39Ar data provide age constraints for movement along these shear zones, and are interpreted to indicate that the Karari, Tallacootra and Coorabie Shear Zones were last active at not, vert, similar1450 Ma. Despite distinct differences in metamorphic grade, the various geological domains bounded by shear zones exhibit evidence for commonality in event histories prior to deformation at not, vert, similar1450 Ma, albeit at different crustal levels. This is interpreted to indicate that deformation at not, vert, similar1450 Ma was responsible for reshuffling of crustal blocks that were already adjacent, rather than amalgamation of exotic terranes. The new data also provide additional evidence for a widespread metamorphic and deformational event at not, vert, similar1530-1550 Ma across the north-western Gawler Craton. The timing of deformation at not, vert, similar1450 is not, vert, similar100 Ma younger than suggested in several published tectonic reconstructions and, importantly, is also significantly older than Grenvillian-age tectonism in adjacent provinces to the west and north.

Exploring for the Future - NDI Carrara 1 gas geochemistry: Molecular composition, carbon and hydrogen isotopes of hydrocarbon gases and the sources of molecular hydrogen and helium

Six gas samples were collected from the possum belly (PB) of the shaker assembly during the drilling of NDI Carrara 1. The sample depths ranged from 1187 m to 1360 m and were from organic-rich Proterozoic rock units. The molecular composition and carbon and hydrogen isotope compositions of the individual PB gas components (methane, ethane, propane and carbon dioxide) suggest that the gases were sourced from local, thermally mature, organic-rich shales and siltstones. After taking into account the air and excess nitrogen content in the PB gases, the helium content of the PB gases is low while the molecular hydrogen contents is up to over a 100 times higher than the helium content. Both molecular hydrogen and helium likely have a major radiogenic origin. Based on the results, there is potential for a yet-to-be quantified unconventional hydrocarbon resource in the vicinity of the NDI Carrara 1 well.

AUSGeoid98 v.1.0 data files: Malcolm (si51-07)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Tallaringa South - TMI grid (AWAGS)

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.
This Tallaringa South - TMI grid (AWAGS) has a cell size of 0.0004 degrees (approximately 42m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 146285 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

The Maranboy tin field, Northern Territory

The Maranboy Tin-field is situated 40 miles south-east of the township of Katherine, in the Northern Territory of Australia. The field is in a small inlier of Lower Proterozoic sediments surrounded by unmineralized sediments of Cambrian and Cretaceous age. The ore mineral is cassiterite, which occurs in fine-grained quartz-tourmaline fissure-lodes. The lodes are infillings of a conjugate system of shear fractures which strike at 110Â° and 160Â°. Available production figures from the field show that from 1915 to 1952, 49,314 long tons of ore were won, from which tin oxide concentrates containing 800.57 long tons of tin were recovered, giving an average grade (by recovery) of 1.66 per cent. Sn. A detailed assessment of the field has shown that of the numerous cassiterite bearing lodes only three can be considered as likely to yield large tonnages of ore in the future. These are the Main Lode, Stannum King Lode, and Cosmopolitan Lode. The data obtained from detailed mapping, sampling, and production records show that they may contain an aggregate of 2,767 tons of ore, assaying 1.23 per cent Sn, per foot of depth. Selective mining by small operators would, as it has in the past, raise the grade with a concomitant reduction in the aggregate of tons of ore per foot of depth. The continued life of the field is dependent upon testing the probable continuance or repetition of ore-shoot at depth, the institution of more efficient mining methods, and the provision of adequate and efficient milling facilities.

Cooper Basin region: surface water package

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Cooper Basin, including streamflow quality and quantity, inundation, and climatological data.
The Cooper Basin underlies 3 surface water catchments: the Diamantina River, Cooper Creek and Bulloo River. All 3 rivers follow a similar flow pattern, with most of the run-off generated in the higher rainfall headwater areas (outside the Cooper Basin) before flowing down into extensive floodplains and ending up in terminal lake systems.
The data on the catchments overlying the Cooper Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.
