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 is characterized by a central uplift, depressed upper surface, and deformed intervening package within Eocene or Early Oligocene carbonate units. The data is provided by the Australian Ocean Data Network and was last updated in April 2026.
Use Cases
- Interpret seismic signatures of impact craters based on the described symmetrical structure and central uplift.
- Compare subsurface features with known impact structures based on the absence of links to deeper volcanic pipes.
- Analyze deformation patterns in carbonate units based on the described highly deformed intervening package.
- Model potential impact events in the Eocene or Early Oligocene period based on the age correlation from seismic wells.
Strengths
- The seismic profile describes a symmetrical structure over approximately 2.5 km.
- The interpretation is based on comparison with known complex impact crater features.
- The data is sourced from a specific geological region, the offshore Canning Basin.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The structure has not been drilled, so definitive evidence like shock metamorphism is unavailable.
