Haines Structure Seismic Profile for Probable Eocene Impact Crater in Western Australia

A single 2D seismic profile from the offshore Canning Basin, Western Australia, interpreted as a possible complex impact crater. The symmetrical Haines Structure spans approximately 2.5 km and exhibits seismic characteristics like a central uplift and sagging overlying horizon. Geoscience Australia published this interpretation as an external scientific journal paper.

Use Cases

• Validate impact crater seismic signatures based on the described symmetrical structure and central uplift.
• Compare marine geological features with other interpreted impact structures on Australia's North West Shelf.
• Model subsurface deformation in carbonate units based on the described highly deformed intervening package.

Strengths

• Seismic interpretation is based on a specific 2D profile showing a symmetrical structure over ~2.5 km.
• Analysis includes comparison with other known impact structures and the absence of features linked to alternative processes like volcanic pipes.

Limitations

• The structure has not been drilled, so definitive evidence like shock metamorphism is unavailable.
• Data is derived from a single 2D seismic profile, limiting three-dimensional analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
