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 Birrindudu NT Detailed Gravity Survey (P200580) contains a total of 3729 point data values acquired at a spacing of 2000 metres. The data is located in NT and were acquired in 2005, under project No. 200580 for Geoscience Australia; Northern Territory of Australia (Northern Territory Geological Survey).

The Carlo Sandstone is part of the Toko Group of the Georgina Basin. This basin, which straddles the Northern Territory-Queensland border, comprises carbonate and clastic rocks of Cambrian and Early Ordovician age; the Toko Group forms the uppermost and dominantly clastic part of the sequence. The Carlo Sandstone, which is of possible Early Ordovician age (? latest Arenig), consists of very fine to fine quartzose sandstone containing siltstone and mudstone pellets. Minor siltstone and mudstone interbeds are present. The unit is conformable with the underlying Nora and overlying Mithaka Formations. Sedimentary structures present include: flute marks, current crescents, various other current lineations, ripple-marks, cross stratification, lamination and various biogenic sedimentary structures. The palaeocurrent measurements indicate uni-directional currents. Fossils are rare except in the uppermost part of the unit where gastropods, pelecypods, nautiloids, trilobites, brachiopods and fish are present. A study of geometry, lithology, sedimentary structures, palaeocurrents and fossils indicate subtidal to intertidal depositional conditions. Of various depositional models, a barrier model is favoured. The Nora Formation represents the offshore, below wave base sediments; the Carlo Sandstone the barrier, either dunes or bars; and the Mithaka Formation the lagoon-bay sediments. The sediments were deposited in an elongate epicontinental sea that also covered the Amadeus, Wiso and Canning Basins.

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 92m) and shows thorium element concentration of the Tiwi Islands, NT, 2006 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2006 by the NT Government, and consisted of 30001 line-kilometres of data at 400m line spacing and 80m terrain clearance.

This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized.

This Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur (CSCBA grid) is a complete spherical cap Bouguer anomaly grid for the Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur Barkley, Northern Territory, 2019. This gravity survey was acquired under the project No. 201901 for the geological survey of NT, QLD. The grid has a cell size of 0.00461 degrees (approximately 500m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 5855 gravity stations were acquired to produce this grid.
