This interpretation forms part of an assessment of the underground hydrogen storage potential of salt features in the Canning Basin region based on integration and interpretation of AEM and other geological and geophysical datasets. A main aim of this work was to interpret the AEM to develop a regional understanding of the near-surface stratigraphy and structural geology. This regional geological framework was complimented by the identification and assessment of possible near-surface salt-related structures, as underground salt bodies have been identified as potential underground hydrogen storage sites. This study interpreted over 20,000 line kilometres of 20 km nominally line-spaced AusAEM conductivity sections, covering an area approximately 450,000 km2 to a depth of approximately 500 m in northwest Western Australia. These conductivity sections were integrated and interpreted with other geological and geophysical datasets, such as boreholes, potential fields, surface and basement geology maps, and seismic interpretations. This interpretation produced approximately 110,000 depth estimate points or 4,000 3D line segments, each attributed with high-quality geometric, stratigraphic, and ancillary data. The depth estimate points are formatted for Geoscience Australia’s Estimates of Geological and Geophysical Surfaces database, the national repository for formatted depth estimate points. Despite these interpretations being collected to support exploration of salt features for hydrogen storage, they are also intended for use in a wide range of other disciplines, such as mineral, energy and groundwater resource exploration, environmental management, subsurface mapping, tectonic evolution studies, and cover thickness, prospectivity, and economic modelling. Therefore, these interpretations will benefit government, industry and academia interested in the geology of the Canning Basin region. {"type": "Polygon", "coordinates": [[[120.0, -24.0], [127.5, -24.0], [127.5, -16.0], [120.0, -16.0], [120.0, -24.0]]]} 120.0 127.5 -24.0 -16.0 AFER ARF Airborne electromagnetics Archean AusAEM Australia’s Future Energy Resources Australia’s Resource Framework Basins Canning Basin Cenozoic Cover thickness Depth to basement Diapir EFTF – Exploring for the Future Electrical and electromagnetic methods in geophysics Energy Geophysical interpretation Groundwater Groundwater hydrology Hydrogen storage Mesoproterozoic Mesozoic Minerals Neoproterozoic Paleoproterozoic Paleozoic Published_External Resource geoscience Salt intrusion Sedimentology Stratigraphy (incl. biostratigraphy Structural geology and tectonics Western Australia sequence stratigraphy and basin analysis) Download data package (zip) [13.21 MB] documentDigital Download data package (zip) [13.21 MB] ZIP Download metadata statement (pdf) [1.1 MB] documentDigital Download metadata statement (pdf) [1.1 MB] PDF
