Hydrogeochemistry of basalt aquifers: Multi-isotope analysis for better understanding of groundwater recharge, flow-paths and surface water interactions of the McBride and Nulla Basalt Provinces - northern Queensland, Australia

Basalt aquifers of the Upper Burdekin region are utilised for stock and domestic purposes and farming as well as contributing to springs, wetlands and rivers. However, the underlying dynamics of the groundwater system are poorly understood. In this study, as part of the Australian Government ‘Exploring for the Future’ Program, targeted hydrogeochemical sampling was undertaken to identify aquifer system processes controlling groundwater recharge, flowpaths and surface water interactions in the McBride and Nulla Basalt Provinces.
Groundwater was sampled from existing and new monitoring bores, and surface water and springs were sampled from selected sites for a wide suite of hydrogeochemical parameters to fingerprint and trace groundwater dynamics. Analytes included: physicochemical parameters (EC, pH, Eh, DO and T); major anions and cations; and isotopes of water (δ18O and δD), DIC (δ13C), and dissolved strontium (87Sr/86Sr) as a tool.
Hydrogeochemical signatures identified in this study support groundwater recharge and groundwater flowpaths being largely restricted to within the basalt provinces. Groundwater typically occurs in a main basal groundwater system and multiple shallow groundwater systems. Groundwater flowpaths of the main basal system were traced from higher elevations in the mountains through to the Burdekin River, showing interaction between the basal and shallow systems. Groundwater recharge to the basal system is indicated from δ18O and δD as being largely from higher elevation and higher rain-out in the mountains. In contrast groundwater recharge to the shallow systems is indicated as being from localised rainfall, as well as local input from rivers and the basal aquifer. Springs across the study area are largely sourced from the main basal groundwater system and form the tributaries that discharge into the Burdekin River. Likewise, some springs contribute to tributary rivers along flowpath. Groundwater signatures also suggest the basalt aquifers discharge directly to the Burdekin River linking groundwater to surface waters in places. 
This study demonstrates how hydrogeochemistry, including isotope analysis, can be used as a tool to reveal fundamental controls on groundwater system processes. The results of this study identify the principal processes of groundwater recharge processes, flowpaths and surface water interactions, which can be used to better understand the basalt aquifer systems in the Upper Burdekin region.

AUSGeoid98 v.1.0 data files:  (sk49-08)

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.

Barkly - Horse Creek, NT, 2001 (P1018), radiometric line data, AWAGS levelled

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 Barkly - Horse Creek, NT, 2001 (P1018), radiometric line data, AWAGS levelled were acquired in 2001 by the NT Government, and consisted of 301463 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Best Practice in Gravity Surveying

Gravity surveys are used to measure small changes in the Earth's gravity field. These changes are due to density variations in the Earth's crust and can be used for a range of investigations such as studies of deep tectonic structures or finding caves in urban engineering studies. The physical property being measured, density variation, is the same in these investigations; it is just the survey parameters and precision required that differ.
This manual serves to give a brief outline of the theory behind gravity surveying and discusses the considerations that need to be addressed when conducting gravity surveys. Gravity survey design and field techniques are discussed including both gravity and positioning equipment. Survey reduction and processing techniques are also discussed.
This manual is not a definitive text on gravity surveying but rather a guide to techniques that have proved to be successful. As such, it is hoped it will be updated as techniques and instrumentation improve. Feedback or suggestions are welcome.

This magnetic grid has a cell size of 0.00039074 degrees (approximately 40m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

Adavale 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 Adavale Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Adavale Basin, including streamflow quality and quantity, inundation, and climatological data.
The Adavale Basin underlies 3 main surface water catchments that contribute to Cooper Creek, including the Barcoo, Bulloo and Warrego rivers. The Adavale Basin geological boundary also intersects the upper parts of the Paroo River catchment and a small part of the Condamine-Balonne catchment.
The data on the catchments overlying the Adavale 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.
