Paterson complete Bouguer first vertical derivative grid geodetic

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 Paterson complete Bouguer first vertical derivative grid geodetic is a complete Bouguer anomaly grid for the Paterson - WA Gravity Survey (P4025). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  This gravity survey was acquired under the project No. 4025 for the geological survey of WA. The grid has a cell size of 0.0037 degrees (approximately 396m). A total of None gravity stations were acquired to produce this grid.

GSQ Thomson Orogen TMI 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 GSQ Thomson Orogen TMI grid geodetic has a cell size of 0.00083 degrees (approximately 87m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2011 by the QLD Government, and consisted of 298198 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Radiometric grid of Australia (Radmap) v4 2019 - Ternary image (K, Th, U)

This image is a ternary image of the radiometric grid of Australia, 2019. The radiometric grid of Australia is derived by merging over 600 airborne gamma-ray spectrometric surveys by the Commonwealth, State and Territory Governments and held in the national radioelement database of Australia. The cell sizes of the original survey grids range from 50 m through 800 m, but most have a cell size of about 100 m. The original survey grids are levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS). The grids were then re-sampled to generate the Radiometric Map of Australia grids with a cell size of about 100m (0.001 degrees). Since the AWAGS traverses are consistent with the International Atomic Energy Agency’s (IAEA) radioelement datum, the new continental merges are levelled to this datum as well. The data quality varies depending on the survey. 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 final grid is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. 
The ternary image was generated by combining filtered K, Th and U grids. The grids were assigned the three usual hues of red (for potassium), green (for Thorium) and blue (for Uranium). This ternary image is very useful for both mineral exploration and environmental mapping.

First order regional magnetic survey in the Prince Charles Mountains, Antarctica and at Heard Island, 1992

This report describes the results of geomagnetic measurements made at repeat stations in the northern Prince Charles Mountains (PCMs) in January 1992 and at Heard Island in February 1992. The PCM survey covered 7of the 9 stations occupied by Crosthwaite in Jan/Feb 1990. The Heard Island work was a reoccupation of a previous magnetic station and observatory site. Multiple sets of DIF or HDF observations were made at each station and sunshots, pier differences and local F surveys were carried out at most stations for confirmation of the 1990 measurements. Variometer records for the 3-5 day occupation of each station were obtained using two portable fluxgate magnetometers developed by F Chamalaun, Flinders University. One was left installedat the first repeat station, the other was carried and reburied at each repeat station. The area covered by the survey was approximately 160 km by 130 km. Station descriptions based mainly on those provided by Crosthwaite are included to facilitate reoccupation. References to earlier geophysical and surveying occupations are given in Crosthwaite (1992).

Mapping freshwater lenses in the Cooper Creek floodplain using airborne electromagnetics

Cooper Creek is a dryland river system that extends from the western Great Dividing Range in Central Queensland to Lake Eyre in South Australia. The middle course of the Cooper Creek is characterised by anabranching river channels across a wide floodplain that flow intermittently due to monsoonal flooding event higher in the catchment. As floodwaters recede, freshwater stagnates within numerous deeper segments of river channels forming ‘waterholes’ which support ecosystems with significant ecological and cultural value. However, there is little evidence that shallow groundwater discharges into these surface water bodies and the link between surface water and groundwater is not well understood. This study aims to demonstrate how airborne electromagnetics (AEM) and other geoscientific data can be integrated to identify recharge within shallow saline groundwater systems, which are so common in arid inland Australia.

The regional water table underneath the floodplain is shallow (38,000 TDS), with a chemical signature suggesting salts were concentrated by evapotranspiration. Surface swelling clays likely limits the amount of recharge that occurs through the floodplain itself. However, a detailed study by Cendón et al (2010) found that during high flow events, floodwater scoured the base of the waterholes allowing freshwater to recharges into the shallow groundwater system forming chemically distinct freshwater lenses.

AEM is a geophysical technique capable of estimating bulk conductivity for the top few hundred metres of the subsurface. Part of the AusAEM Eastern Resource Corridor survey (Ley-Cooper 2021) crossed the Cooper Creek floodplain with a 20km line spacing. The bulk conductivity models delivered as part of this survey resolved the top of the saline water table regionally. In several locations, we identified resistive lenses sitting on the shallow water table which coincide with river channels that are frequently inundated.

Rockhampton International Map of the World (IMW) 1:1 000 000 topographic map

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

Petroleum systems modelling of the Carrara Sub-basin: 1D and 2D burial and thermal history modelling

This study aims to understand both the burial and thermal history of the Carrara Sub-basin to further develop an understanding of possible geo-energy resources, particularly that for unconventional resources such as shale gas. A 1D and 2D model were developed using data from the above mentioned seismic and drilling campaigns, combined with previously published knowledge of the basin. This work contributes to Australia’s Future Energy Resources (AFER) Project, specifically the Onshore Basin Inventories study, which aims to promote exploration and investment in selected underexplored onshore basins. Inventory reports and petroleum systems modelling are being undertaken in select basins to highlight the oil and gas potential in underexplored provinces and to increase the impact of existing datasets.
