L029 Heywood Experimental Seismic Survey, Victoria, 1956

An experimental seismograph survey was conducted near Heywood in the Western District Basin, Victoria, during November and December 1956 by the Bureau of Mineral Resources, Geology and Geophysics. The work was requested by Frome-Broken Hill Pty. Ltd. to test seismic exploration techniques through a basalt surface layer. Several short traverses were shot, testing pattern, air-shooting, and single shot-hole techniques, with reflections recorded from depths down to eleven thousand feet.

Use Cases

• Test seismic reflection techniques for deep sediment mapping based on the described survey methods.
• Analyze the effectiveness of pattern and air-shooting versus single shot-hole methods based on the experimental results.
• Correlate seismic reflections with stratigraphic horizons as attempted in the original study.
• Assess seismic data quality in areas with basalt or tuff cover based on the survey's findings.

Strengths

• Survey conducted by a national geological authority, the Bureau of Mineral Resources, Geology and Geophysics.
• Reflections were recorded from depths down to eleven thousand feet.
• Multiple seismic techniques were tested, including pattern, air-shooting, and single shot-hole methods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single 1956 survey.
