L029 Heywood Experimental Seismic Survey in Western District Basin, 1956

An experimental seismograph survey near Heywood, Victoria, was conducted in November and December 1956 by the Bureau of Mineral Resources, Geology and Geophysics. Several short traverses tested pattern, air-shooting, and single shot-hole techniques to record reflections through a basalt surface layer. Good reflections were recorded from depths down to eleven thousand feet in areas without basalt, and some poor-quality reflections appeared up to 5 seconds after the shot.

Use Cases

• Compare seismic reflection quality based on different shooting techniques (pattern, air-shooting, single shot-hole) mentioned in the description
• Analyze the feasibility of recording reflections through basalt and tuff layers as discussed in the survey report
• Correlate seismic reflection data with stratigraphic horizons as attempted in the original study
• Evaluate sub-surface information obtainability in the Heywood area for mineral exploration

Strengths

• Survey conducted by a national geological authority (Bureau of Mineral Resources, Geology and Geophysics)
• Describes specific experimental techniques (pattern, air-shooting, single shot-hole) and their comparative results
• Reports reflections recorded from depths down to eleven thousand feet and time delays up to 5 seconds

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is from a single, focused 1956 survey; temporal and geographic scope is limited
