The Bureau of Mineral Resources made an experimental seismic survey in the Otway Basin, Victoria and SA, and in the Sydney Basin, NSW, from April to November 1965 and from mid February to mid March 1966. The survey used explosives as an energy source to obtain seismic reflection data for comparison with the results from an experimental 'Vibroseis' survey carried out for the Bureau by Seismograph Service Ltd during 1964.

Techniques for recording deep crustal reflections were developed on an experimental seismic survey at Mildura, Victoria and Broken Hill, NSW, during September to December 1968. The survey was carried out preparatory to a seismic reflection survey on the 'Geotraverse' project, a project initiated by the Australian Upper Mantle Commitee to study the Earth's crust and upper mantle along a line across the Precambrian shield in Western Australia.

<p>Geoscience Australia conducted the Gunnedah Basin Seismic Survey during January to April 1991. The major aim of the seismic survey was to record deep seismic reflection data across the Gunnedah Basin and bounding margins. The seismic survey would also address several problems relating to the geometry of structural units and major faults. The survey recorded 253 km of eight-fold Common-Middle-Point (CMP) seismic data. The seismic data have been processed, with the data showing good seismic reflection images of the main structural features targeted in the seismic survey.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74952</b>

Terrex Seismic was contracted by ANSIR to conduct seismic recording operations for Ballarat Goldfields NL to acquire approximately ten (10) kilometers of high resolution 2D data within the Ballarat region of Victoria. Recording commenced on the 8th May 2006 and was completed 3 days later on the 11th May 2006. The acquisition area of the Ballarat High-Res 2D was situated approximately eight (8) kilometers south of the township of Ballarat.

A ~400 km long deep crustal reflection seismic survey was acquired in central Victoria, Australia, in 2006. It has provided information on crustal architecture across the western Lachlan Orogen and has greatly added to the understanding of the tectonic evolution. The east-dipping Moyston Fault is confirmed as the suture between the Delamerian and western Lachlan Orogens, and is shown to extend down to the Moho. The Avoca Fault, the boundary between the Stawell and Bendigo Zones, is a west-dipping listric reverse fault that intersects the Moyston Fault at a depth of about 22 km, forming a V-shaped geometry. Both the Stawell and Bendigo Zones can be divided broadly into a lower crustal region of interlayered and imbricated metavolcanic and metasedimentary rocks and an upper crustal region of tightly folded metasedimentary rocks. The Stawell Zone was probably part of a Cambrian accretionary system along the eastern Gondwanaland margin, and mafic rocks may have been partly consumed by Cambrian subduction. Much of the Early Cambrian oceanic crust beneath the Bendigo Zone was not subducted, and is preserved as a crustal-scale imbricate thrust stack. The seismic data have shown that a thin-skinned structural model appears to be valid for much of the Melbourne Zone, whereas the Stawell and Bendigo Zones have a thick-skinned structural style. Internal faults in the Stawell and Bendigo Zones are mostly west-dipping listric faults, which extend from the surface to near the base of the crust. The Heathcote Fault Zone, the boundary between the Bendigo and Melbourne Zones, extends to at least 20 km, and possibly to the Moho. A striking feature in the seismic data is the markedly different seismic character of the mid to lower crust of the Melbourne Zone. The deep seismic reflection data for the Melbourne Zone have revealed a multilayered crustal structure that supports the Selwyn Block model.

<p>The Australian Geodynamics Cooperative Research Centre (AGCRC), through Geoscience Australia conducted a seismic reflection survey in various localities in the eastern Lachlan Orogen of NSW, from October to November 1997. The objectives of the project were to obtain a better understanding of sub-surface geology at a regional and local scale and, in particular, provide more information on: 1. basement control on basin development 2. regional crustal thickness and major features within the basement 3. stratigraphic architecture of the basins 4. structural architecture of the basins 5. the location of fluid flow pathways The seismic survey acquired 105 km of 10 fold CMP (common midpoint) deep (20 second TWT) reflection seismic data along three traverses over a 6 week acquisition period. In addition to the seismic data, gravity observations were made at 300 m intervals along the lines. Drill cutting samples were also collected for analysis.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74883</b>

<p>Geoscience Australia conducted a seismic reflection survey in various localities throughout Tasmania between January and April 1995. This seismic survey formed part of AGSO project `TASGO' (b103201), a National Geoscience MappingAccord (NGMA) project carried out in conjunction with the Tasmanian Geological Survey (within Tasmania Development and Resources). The seismic survey obtained 134 km of 10 to 20 fold common mid-point (CMP) deep reflection seismic data along six traverses over an 8 week acquisition period. In addition, gravityobservations were made by the Tasmanian Geological Survey at 120 m intervals along five of the lines. Statewide aeromagnetic data has been interpolated to provide profiles along eachseismic line, and shot hole cuttings and water samples were taken for later analysis. The reflection crew provided support for AGSO's refraction and tomography data acquisition which is reported separately.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74942</b>

<p>Geoscience Australia conducted a seismic survey in the Denison Trough, in the western part of the Bowen Basin in Queensland in 1978 and 1979. The aims of the survey were to delineate the configuration of the Trough, in particular the lower part of the Permian sequence and basement, and to provide stratigraphic information from the Permian sequence that, in conjunction with current Geological Survey of Queensland (GSQ) stratigraphic studies, would enable reliable stratigraphic correlations to be made throughout the Trough. The survey obtained 457 km of digitally recorded six-fold Common-Depth-Point seismic reflection data.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74974</b>

The 2005 Thomson Lachlan 2D Seismic Survey was conducted by Terrex Seismic Pty, Ltd for ANSIR (Australian National Seismic Imaging Resource) and the New South Wales Department of Primary Industries - Mineral Resources. The survey was situated near the township of Tilpa (on the Darling River) in central NSW. There were three lines totalling 301.88km chained at a 40m station interval. The traverses cross a section of the Thomson Orogen gravity high where it is narrow and where the southern part is expressed by linear magnetic highs that extend as far south as the possible southern edge of the Thomson Orogen. These traverses also cross a narrow part of the Nelyambo Basin and the Mt Jack High to the south. Raw data for this survey are available on request from clientservices@ga.gov.au

<p>This investigation was a joint project between the Department of Geology, University of Melbourne, the Department of Earth Sciences, Monash University, and Geoscience Australia to investigate the suitability of the seismic reflection technique for determining the crustal structure within central Victoria. The project was initiated as a pilot study for a proposed 400 km deep crustal transect across Victoria in 1991-92. Funding for the project was provided jointly by the Victorian Department of Industry, Technology and Resources (ITR) and the BMR. Data acquisition was carried out during the university vacation period from the 17th to 24th June 1989 to enable participation of university staff and students. Two traverses were completed, the first 6 km long (line 89-09), and the second 8 km long (line 89-10), each being up to twelve fold common mid-point (CMP). The traverses were located on the downdip side of the Mt. Ida - McIvor fault approximately 40 km north of Heathcote. Traverse orientation was east-west and perpendicular to regional strike, and was constrained by the requirement to use existing roads and tracks in the area.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74955</b>
