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, interpreted as a possible complex impact crater. The feature, named the Haines Structure, is symmetrical over ~2.5 km and exhibits seismic characteristics of a crater. The data is provided by Geoscience Australia and was last updated in April 2026.

Use Cases

• Training seismic interpretation models based on the described crater morphology features like central uplift and sagging horizons.
• Comparative analysis of impact structures using the seismic character described for the Haines Structure.
• Studying the geology of the Eocene or Early Oligocene period in the Canning Basin based on the age correlation mentioned.

Strengths

• Describes a specific seismic structure with a defined spatial scale of ~2.5 km.
• Provides a detailed geological interpretation based on seismic character comparison with known impact craters.
• Data originates from Geoscience Australia, a national geological survey.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is based on a single 2D seismic line, limiting three-dimensional analysis.
• The impact origin is interpreted from seismic data, as the structure has not been drilled to confirm shock metamorphism.
