Heywood Experimental Seismic Survey, Western District Basin, 1956

An experimental seismograph survey was conducted 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 basalt layer. Several short traverses tested various surface conditions and shooting techniques, with reflections recorded from depths down to eleven thousand feet.

Use Cases

• Compare seismic reflection quality based on different surface conditions mentioned in the description
• Evaluate the effectiveness of pattern and air-shooting techniques versus single shot-hole methods
• Correlate seismic reflections with stratigraphic horizons in the Western District Basin
• Study subsurface information obtainable by seismic exploration in areas with basalt cover

Strengths

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

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Data may reflect geographic and temporal bias inherent to a single 1956 survey in Victoria
