Northeast Coalfields (ECCP) (P197851), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Northeast Coalfields (ECCP) (P197851) contains a total of 401 point data values acquired at a spacing between 750 and 1000 metres. The data is located in TAS and were acquired in 1978, under project No. 197851 for Mineral Resources Tasmania (MRT).

GSSA p1280tmig

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 GSSA p1280tmig has a cell size of 0.00042 degrees (approximately 44m). 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 109753 line-kilometres of data at 200m line spacing and 60m terrain clearance.

AUSGeoid98 v.1.0 data files:  (sd57-01)

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.

Known Thick Underground Halite Deposits - Version 1 (2021)

Underground halite, or salt, deposits can potentially be used for large scale storage of hydrogen. This dataset maps the spatial distribution of known, thick underground halite deposits across Australia. Halite sequences included in this map are at least 100 metres thick (to ensure sufficient storage capacity) and are located onshore. Known, thick halite deposits are located in the Carnarvon, Amadeus and Adavale basins. 
Underground halite deposits have not been extensively explored for across Australia and additional halite deposits suitable for large scale hydrogen storage may exist. Geoscience Australia, through the Exploring for the Future (EFTF) program, is therefore exploring for underground halite deposits to further our understanding of sub-surface halite distribution for potential hydrogen storage. This map may be updated periodically to reflect new halite discoveries found during the EFTF program. 
This dataset is published with the permission of the CEO, Geoscience Australia.

EOMAP_20220329.0835 Cocos (Keeling) Marine Park Satellite-Derived Bathymetry Acquisition (20220020S)

Parks Australia - Indian Oceans Territory (IOT) Grants Project: Satellite-Derived Bathymetry and Seafloor Habitat Classification Mapping of Cocos (Keeling) Island Marine Park
 
This project mapped Satellite-derived Bathymetry (SDB) and seafloor habitats at 2m horizontal spatial resolution, for the shallow waters (~0-25 m) of the Cocos (Keeling) Islands Marine Park. SDB data was processed using EOMAP's proprietary software and algorithm package Watcor-X, which generates SDB using multi-spectral satellite data. The SDB is based on the physics-based inversion method of the radiative transfer equation which models the pathway of light and its interaction through different media (e.g. atmosphere and water column). The thematic classification of the seabed was based on multispectral satellite image analytics. Satellite imagery was pre-processed by applying a set of image correction procedures to reduce environmental noise, resulting in a standardised reflectance surface of the subsurface and seafloor. The information on seafloor reflectance at different wavelengths was used to run an object-based classification procedure which groups objects of similar spectral characteristics, shape and texture into different classes of major seafloor habitat type.
 
These critical geospatial data layers provide the essential environmental baseline information for the long-term monitoring and management of the IOT Marine Parks. Having access to digital, georeferenced, high-resolution, satellite-derived maps of bathymetry and benthic habitats of shallow water areas, is of fundamental use in the areas of navigation and safety-at-sea, ecological research, environmental modelling, management and conservation, and monitoring the impacts from climate change. This dataset is not to be used for navigational purposes.

Hyperspectral Mapping of Mineral Assemblages Associated with Gold Mineralization in the Central Pilbara, Western Australia

The Indee district, located in the Central Pilbara tectonic zone of the North Pilbara terrain in Western Australia, contains Archean lode gold deposits and epithermal gold systems. Hydrothermal alteration assemblages associated with these deposits contain the minerals pyrophyllite, white mica, chlorite, and tourmaline. Known prospects are surrounded by flat areas of poorly exposed calcretised bedrock, calcretes, rock float, and sandy soils. Two adjacent lines of airborne hyperspectral data (HyMapÂ®) were acquired. To produce mineral abundance maps, these data were processed to correct for atmospheric and illumination conditions and then calibrated to reflectance data using field spectra. This analysis successfully mapped the distribution of pyrophyllite, white mica, Mg chlorite, Fe chlorite, calcite, dolomite, kaolinite, tourmaline, hematite, and goethite. Alteration assemblages associated with the Camel 2 deposit, which is located along the Mallina shear zone, were found to be characterized by pyrophyllite and Al-rich white mica, the latter having an AlOH absorption feature at 2.194 Âµm. In contrast, alteration assemblages associated with epithermal deposits south of the Mallina shear zone are characterized by Al-poor white mica with a longer wavelength absorption feature at 2.210 Âµm, the shift reflecting the change in Al chemistry (Tschermak substitution). Tourmaline is also present near the epithermal-like deposits, suggesting that it may be an integral part of these systems. Fe chlorite is associated with both the mesothermal and epithermal systems but is also pervasive as a regional metamorphic mineral. Regolith-related carbonates are common throughout the area and their compositions are determined by the hyperspectral processing. Mineral abundance images were verified by PIMAÂ® (portable infrared mineral analyser) analysis of ground samples, and assays of rocks in previously unknown areas of pyrophyllite and white mica confirmed the presence of anomalous gold. These results show that mineral maps and compositional information derived from hyperspectral analysis are extremely valuable for exploration, even in poorly exposed, regolith-dominated districts such as Indee.

Australian Mineral Exploration - A Review of Exploration for the Year 2006: Extended edition

Australian mineral exploration spending in 2005-06 rose by 20.6% to a record $1240.7 million, 36.9% of which was spent on the search for new deposits. 
Western Australia dominated with 47.6% of Australian mineral exploration spending while South Australia, New South Wales, Victoria and Queensland had record expenditure. Tasmanian spending rose by 172%. 
Gold remained the main target, but its share of spending was eroded by growth in nickel, copper, iron ore, coal and uranium exploration. 
Exploration results were announced for a wide range of commodities from across the country including:
Mineral sands (Gullivers, South Australia, and Cooljarloo North, Western Australia) 
Nickel (Saxon, Tasmania) 
Gold-copper (Tekapo, Northern Territory) 
Gold (Tandarra, Victoria, and Tropicana, Western Australia) 
Base metals (Cuttaburra, New South Wales) 
Copper (Rocklands, Queensland)

Vlaming Sub-Basin Marine Environmental Survey (GA-0334/S. Supporter GP1373)(NCIP Program) - Sidescan grids

Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone). This dataset comprises sidescan grids.

For each deposit (or, in some cases, district) the dataset includes information on:
1.  Name (including synonyms), location and GA identifying numbers;
2.  Tectonic province that hosts the deposit;
3.  Type(s) and age(s) of mineralising events that produced/affected the deposit (including metadata on ages);
4.  The metal/mineral endowment of the deposit;
5.  Host rocks to the deposit;
6.  Spatially and/or temporally associated magmatic rocks;
7.  Spatially and temporally associated alteration assemblages (mostly proximal, but, in some cases, regional assemblages);
8.  The Fe-S-O minerals present in the deposit and relative abundances where known;
9.  Sulfate minerals present;
10. Peak metamorphic grade;
11. Data sources; and
12. Comments.
This document presents more detailed descriptions of the metadata presented in the compilation. The dataset is presented in Appendix A. Appendix B presents a national classification of geological provinces based mostly on existing State survey classifications; Appendix C presents a deposit classification based on the classification proposed by Hofstra et al. (2021); and Appendix D presents mineral abbreviations used in the dataset.
