Haddon Downs in South Australia was surveyed in October and November 1957. The experimental seismic survey recorded two important refractors and mapped subsurface structure within the Eromanga Sub-basin. The data was likely collected by Santos Ltd. and is hosted by the Australian Ocean Data Network.
Use Cases
- Mapping subsurface geological structure based on recorded seismic refractors.
- Estimating thickness of sedimentary sections based on interpreted depths.
- Correlating seismic data with surface anticline structures mentioned in the description.
- Analyzing seismic velocities to infer rock types, such as dense elastic or crystalline limestone.
Strengths
- Survey recorded two specific refractors with velocities of 10,250 ft/sec and 17,000 ft/sec.
- Interpreted depths for geological boundaries, such as a Mesozoic base at 7,250 feet.
- Survey area is described as having at least 5,500 feet of Mesozoic section.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
