The survey spanned from the north-eastern end of the Yathong-Ivanhoe Trough and extended across the Forbes, Dubbo, and Coonabarabran regions of New South Wales. A total of 15, 090-line kilometres of new AEM and magnetic geophysical data were acquired. This survey was entirely funded by GSNSW and GA managed acquisition, quality control, processing, modelling, and inversion of the AEM data.The survey was flown by Xcalibur Aviation (Australia) Pty Ltd using a 6.25 Hz HELITEM® AEM system. The survey blocks were flown at 2500-metre nominal line spacings, with variations down to 100 metres in the Coonabarabran block. It was flown following East-West line directions. Xcalibur also processed the acquired data. This data package includes the acquisition and processing report, the final processed AEM data, and the results of the contractor's conductivity-depth estimates.

Brief description

Yathong, Forbes, Dubbo, and Coonabarabran Airborne Electromagnetic Survey Blocks.

Geoscience Australia (GA), in collaboration with the Geological Survey of New South Wales (GNSW), conducted an airborne electromagnetic (AEM) survey from April to June 2023. The survey spanned from the north-eastern end of the Yathong-Ivanhoe Trough and extended across the Forbes, Dubbo, and Coonabarabran regions of New South Wales. A total of 15, 090-line kilometres of new AEM and magnetic geophysical data were acquired. This survey was entirely funded by GSNSW and GA managed acquisition, quality control, processing, modelling, and inversion of the AEM data.

The survey was flown by Xcalibur Aviation (Australia) Pty Ltd using a 6.25 Hz HELITEM® AEM system. The survey blocks were flown at 2500-metre nominal line spacings, with variations down to 100 metres in the Coonabarabran block. It was flown following East-West line directions. Xcalibur also processed the acquired data. This data package includes the acquisition and processing report, the final processed AEM data, and the results of the contractor's conductivity-depth estimates. The data package also contains the results and derived products from a 1D inversion by Geoscience Australia with its own inversion software.

The survey will be incorporated and become part of the national AusAEM airborne electromagnetic acquisition program, which aims to provide geophysical information to support investigations of the regional geology and groundwater.

1. A data release package summary PDF document
2. The survey logistics and processing report and HELITEM® system specification files

Notes

Purpose
The Yathong-Forbes-Dubbo, and Coonabarabran survey intends to support and better characterise the salinity, recharge and architecture of the aquifers within the upper few hundred metres of the subsurface. It will also provide data at a reconnaissance scale to allow the study of: a) Trends in regolith thickness variability. b) Variations in bedrock conductivity. c) Electrical conductivity of key bedrock (lithology-related) units undercover. d) Expand the state’s understanding of the groundwater systems of the region.These aerial surveys provide precompetitive information to inform decision-making by government, community, and industry on the sustainable development of Australia's mineral, energy, and groundwater resources. By gathering, analysing, and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential.
