Timbury Hills No.2 Bore: Seismic Velocity Survey

On 30 March 1960, a seismic velocity survey was conducted on the A.A.O. Timbury Hills No.2 bore near Roma, Queensland. The dataset documents subsurface formations, primarily Mesozoic sandstone and shale down to 3845 feet, where the harder Timbury Hills Formation was encountered. It was a joint investigation by the Bureau of Mineral Resources and Associated Australian Oilfields N.L., supported by detailed lithological and electric logs.

Use Cases

• Calibrating seismic interpretations based on direct velocity measurements from a borehole.
• Analyzing the lithological transition from Mesozoic sediments to the underlying Timbury Hills Formation.
• Studying the geological structure of the Great Artesian Basin near Roma, Queensland.

Strengths

• Provides specific, dated field measurements from a 4400-foot-deep borehole.
• Includes supporting lithological and electric logs for context, as noted in the description.
• Represents a foundational historical survey for the region, hosted by Geoscience Australia.

Limitations

• Key metadata such as row count, specific column names, and license information is unavailable across all sources.
• The dataset's format is listed as PDF/HTML, which suggests it may be a scanned report rather than structured, machine-readable data.
• Conflicting 'last updated' dates (2026-05-14 and 2026-05-07) on the same platform indicate potential metadata inconsistency.
