L029 Heywood Experimental Seismic Survey in Western District Basin, 1956

An experimental seismograph survey was carried out near Heywood in south-western 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 if reflections from deeper sediments could be recorded through a surface layer of basalt. Several short traverses were shot to test a variety of surface conditions and shooting techniques, including pattern, air-shooting, and conventional single shot-hole methods.

Use Cases

• Compare seismic reflection quality based on different shooting techniques (pattern, air-shooting, single shot-hole) mentioned in the description.
• Analyze the correlation between seismic reflections and stratigraphic horizons as attempted in the survey.
• Assess the challenge of recording reflections through specific geological covers like tuff with basalt bands on Mt. Clay.
• Study sub-surface information obtainable by seismic exploration in the Heywood area as discussed.

Strengths

• Survey conducted over a defined period (November and December, 1956).
• Reflections were recorded from depths down to eleven thousand feet in areas without basalt.
• Multiple seismic techniques (pattern, air-shooting, single shot-hole) were tested and compared.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
