DCD 2D Seismic Survey: Deep Crustal and Groundwater Imaging in Southeastern Australia

Acquired from May to August 2022, this 2D reflection seismic survey covers 1256 km across five deep crustal lines and one high-resolution line in South Australia, Victoria, and New South Wales. It was conducted by Geoscience Australia in collaboration with state geological surveys under the Exploring for the Future program. The data includes DMO Stack, Post-Stack Time Migration, and Pre-Stack Time Migration products.

Use Cases

• Imaging deep crustal structures based on five long seismic lines totaling over 1000 km.
• Refining hydrogeological models for groundwater resources based on a high-resolution 56 km line.
• Informing mineral exploration decisions based on precompetitive data from the Curnamona Province and Delamerian Orogen.
• Supporting regional geological mapping based on coverage of the Flinders Range, Murray-Darling basin, and Darling Basin.

Strengths

• Survey spans 1256 km across five distinct seismic lines.
• Data includes both deep crustal (20/8 second) and shallow high-resolution (4 second) processing.
• Project is a collaboration between Geoscience Australia and three state geological surveys.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
