Haines Structure: Seismic Profile of a Probable Eocene Impact Crater in Western Australia

A single 2D seismic profile from the offshore Canning Basin, Western Australia, images a symmetrical structure spanning approximately 2.5 km. The Australian Ocean Data Network hosts this data, which was last updated on 2026-04-10. The profile is interpreted as a probable complex impact crater within Eocene or Early Oligocene carbonate units.

Use Cases

• Training models for seismic feature classification based on the described symmetrical structure and centrally uplifted basal surface.
• Comparative analysis of impact crater morphology using the described key elements that characterise known complex impact craters.
• Geological mapping of the offshore Canning Basin based on the seismic correlation to petroleum exploration wells mentioned in the description.

Strengths

• Data is sourced from the authoritative Australian Ocean Data Network.
• The seismic structure is described with specific morphological details, including a symmetrical shape over ~2.5 km and a centrally uplifted basal surface.
• Last update timestamp is precisely recorded as 2026-04-10 22:05:16.316120.

Limitations

• Row count, column definitions, and sample data are unavailable, which may limit suitability assessment.
• The structure has not been drilled, so distinguishing characteristics like shock metamorphism are not available for verification.
• Description metadata is limited; actual data quality and format require manual inspection after download.
