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 interpreted as a possible complex impact crater. The feature, named the Haines Structure, spans approximately 2.5 km and is situated within carbonate units of Eocene or Early Oligocene age. The data was published by Geoscience Australia Data and was last updated on 2026-05-14.

Use Cases

• Training models for seismic feature classification based on described crater characteristics like central uplift and sagging horizons.
• Comparative analysis of impact crater morphology using the described symmetrical structure and deformed seismic packages.
• Geological mapping and age correlation using the Eocene or Early Oligocene carbonate unit context mentioned in the description.

Strengths

• The dataset is based on a specific seismic profile from a defined geographic location, the offshore Canning Basin.
• The description provides detailed morphological characteristics, including a symmetrical structure over ~2.5 km with a centrally uplifted base and sagging upper horizon.
• The geological age context is provided, placing the structure within Eocene or Early Oligocene carbonate units.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data is derived from a single 2D seismic line, which may not fully represent the three-dimensional structure.
