Taltingan 1 100k magnetic grid geodetic

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 Taltingan 1 100k magnetic grid geodetic has a cell size of 0.00021 degrees (approximately 21m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1994 by the NSW Government, and consisted of 56310 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

AREMI Buildings (Web Mercator) MapServer

This web service shows areas or locations occupied by an existing high-density urban development or known individual building structures in peri-urban and remote locations. Data used in this service is of varying levels of coverage and quality since it is aggregated from a variety of sources. 
The intended purpose of the service is to provide preliminary, first-pass information about urban environment, building structures and their distribution in landscape, as one of constraints on future development. Users should carry out further and more detailed investigations because this information is not meant to be a definitive source or support engineering phase planning. 
The service has layer scale dependencies.

Kurnalpi 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.

Cooper Basin region: Hydrogen potential package

The potential for hydrogen production in the Cooper Basin region is assessed to provide a joint information base for hydrogen generation potential from renewable energy, groundwater, and natural gas coupled with carbon capture and storage (CCS). Hydrogen generation requires water, whether using electrolysis with renewable energy or steam methane reforming (SMR) of gas with CCS. The data package includes the regional renewable energy capacity factor, aquifers and their properties (potential yield, salinity, and reserves or storativity), and geological storage potential of carbon dioxide (CO2). This data guide gives examples of how the compiled data can be used.
The renewable hydrogen potential is assessed based on renewable energy capacity factor and groundwater information (potential yield, salinity, and reserves or storativity). Three aquifers from overlying basins (Eromanga and Lake Eyre basins) are included in the assessment. The Cooper Basin region has high renewable hydrogen potential. The presence of good aquifer throughout the basin combined with high renewable energy capacity factor resulted in significant areas with high hydrogen potential.
The Cooper Basin has significant hydrocarbon resources, primarily for gas (Geoscience Australia, 2022). Although most known hydrocarbon resources have depleted since production began in the 1960s (Smith et al., 2015), a large amount of gas remains, including conventional gas (1,058 PJ reserves and 1,598 PJ resources) and unconventional basin-centred gas (2,265 PJ resources). An assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin are prospective for potential CO2 geological storage (Bradshaw et al., 2023). Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from SMR coupled with CCS.

L050&L057 Giles-Carnegie seismic reflection and refraction survey, SA_WA, 1961

Seismic refraction velocities were measured in the Archaean or crystalline basement rocks at Mount Davies (SA) and Giles (WA) where the rocks are near the surface. Refraction velocities were measured in the Proterozoic outcrops of the Rawlinson Range and Lake Hopkins. Refraction velocities were measured in the Palaeozoic and Mesozoic rocks at Lake Christopher, and in the Mesozoic rocks at Iragana Turnoff.
Those velocities were used as a basis for a suggested correlation between refractors recorded at traverses between Signpost and Mount Beadell. Reflection tecniques, as tried 9 yielded fair reflections at Mount Beadell, and doubtful reflection alignments at trig. point NMF 19. It is likely that the sedimentary basin shows an increasing thickness of sediments from Signpost to Mount Beadell, At Mount Beadoll there is at least 6000 ft of apparently post-Proterozoic sediments. The thickness and degree of metamorphism of Proterozoic ratio below this have not been determined. Present evidence suggests an area of uplift under Lake Breaden.

Cooper Basin regional geology

Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide gives examples of how the compiled data can be used. It supports a data package that presents core photographs, existing knowledge of the stratigraphy, and structural elements for the Cooper Basin and the overlying Simpson, Eromanga and Lake Eyre basins.
Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Cooper Basin region. The Cooper Basin includes 2 stratigraphic groups. From deepest to shallowest, these are the Gidgealpa Group and the Nappamerri Group. The overlying Cuddapan Formation is considered part of the Simpson Basin instead of the Cooper Basin. Overlying the Cooper Basin are the geological formations of the Eromanga and Lake Eyre basins.
The frameworks include the stratigraphic intervals used by the Trusted Environmental and Geological Information (TEGI) Program. From the base of the Cooper Basin to the top of the Lake Eyre Basin, the sedimentary sequence is categorised into 16 play intervals for resource assessment mapping and 9 hydrostratigraphic intervals for characterising groundwater systems (Wainman et al., 2023).
Structural elements maps summarise where the sedimentary sequence has been deposited and later deformed by crustal movements. Structure information is used in assessing the geological potential for resources and interpreting groundwater flow and connectivity at the basin scale. The stratigraphic frameworks and structural elements provide the basic geological context for the Cooper Basin region geological, resource and environmental assessments.

Source Rocks of the Birrindudu Basin, perspectives from new sampling program

The Paleo- to Mesoproterozoic Birrindudu Basin is an underexplored frontier basin straddling the Northern Territory and Western Australia and is a region of focus for the second phase of Geoscience Australia’s Exploring for the Future (EFTF) program (2020–2024). Hydrocarbon exploration in the Birrindudu Basin has been limited and a thorough assessment of the basin's petroleum potential is lacking due to the absence of data in the region. To fill this data gap, a comprehensive analytical program including organic petrology, programmed pyrolysis and oil fluid inclusion analysis was undertaken on cores from six drill holes to improve the understanding of the basin’s source rock potential and assess petroleum migration. Organic petrological analyses reveal that the primary maceral identified in the cores is alginite mainly originating from filamentous cyanobacteria, while bitumen is the most common unstructured secondary organic matter. New reflectance data based on alginite and bitumen reflectance indicate the sampled sections have reached a thermal maturity suitable for hydrocarbon generation. Oil inclusion analyses provide evidence for oil generation and migration, and hence elements of a petroleum system are present in the basin.

Depth to Basement of Northwest Queensland map

The depth to basement map consists of a compilation of point located depth values, in meters below the topography. The depth values are sourced from drill hole data, magnetic depth estimates and seismic refraction data. The point depths were gridded using the minimum curvature technique with a cell size of 1000 m. 
The depth to basement map shows the depth of burial of basement geology beneath younger flat-lying cover material. A companion map "Basement Geology of North Queensland" (GEOCAT No. 68592) shows the basement features for which this depth to basement is referring. 
Drill hole data was compiled from a number of sources and consists of holes that entered basement only. The data consists of:
- Mineral, Stratigraphic and Coal drill holes sourced from the Queensland Department of Mines and Energy's Interactive Resource and Tenure Maps system (http://www.dme.qld.gov.au/mines/tenure_maps.cfm)
- Drill holes included with a GIS of the North Queensland Gold and Base Metals Study (Georgetown) sourced from the Queensland Department of Mines and Energy web site (http://www.dme.qld.gov.au/mines/seqgis.cfm#Georgetown)
- Drill holes from the North-West Queensland Mineral Province Report.
Seismic depth estimates were generated from refracted first break seismic data for the North Queensland seismic lines 06GA-M4, 06GA-M5 and 07GA-IG1.
Magnetic depth estimates were sourced from the following:
- Magnetic depth determinations from the North-West Queensland Mineral Province Report.
- Estimated depths to magnetic basement Springvale and Boulia 1:250 000 sheet areas.
- Depth to magnetic source estimates from airborne magnetic profile data using the Naudy method. 
- Depth estimates from forward modelled profiles extracted from a magnetic grid using a dipping dyke as the source body.
