<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>

<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>

Geoscience Australia conducted the Yilgarn-Officer-Musgrave 2D Seismic Survey. The survey involves the acquisition of seismic reflection over the Yilgarn Craton, Officer Basin and Musgrave Province of Western Australia. The survey consisted of one line, totalling 484.2 kms. The project is a collaborative project between Geoscience Australia and the Geological Survey of Western Australia and is part of the ongoing cooperation under the National Geoscience Agreement (NGA). Funding of this project is through the Western Australian Government's Royalties for Regions Exploration Incentive Scheme and Geoscience Australia's Onshore Energy Security Program. The primary objective of the project is to image the western Officer Basin, one of the Australia's underexplored sedimentary basins. In addition this survey will gather new data to improve the understanding of the Yilgarn Craton and its boundary with the Musgrave Province.

The Bureau of Mineral Resources, Geology and Geophysics (BMR) did a reconnaissance seismic survey in the central portion of the Bowen Basin in November, 1960. The objectives of the survey were to determine the structure of the Basin and the thickness of sediments by traversing from the western margin of the Basin near Anakie to the eastern margin east of Duaringa. Two other seismic surveys conducted in this Bowen Basin are Cooroorah Anticline seismic survey in 1959 (survey L037) and 254km seismic survey near the towns of Duaringa and Blackwater (survey L129).

Processed Stacked and Migrated SEG-Y seismic data and section images for the Youanmi Deep Crustal Seismic Survey. This survey was conducted under a National Geoscience Agreement with the Western Australia Geological Survey. Funding was through the Onshore Energy Security Program and Western Australia's Exploration Incentive Scheme. The objective of the survey was to image the northwest Yilgarn Craton to the Ida Fault crossing the Meekatharra structural zone, a focus of gold mineralization. Data are supplied as SEG-Y files, TIFF and PDF images. 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>

This report contains the results of a seismic survey on the Nerrima Dome, a major structure within the Fitzroy Basin and near its south-western boundary. The dome is situated near the Fitzroy River about 100 miles south-east of Derby in the West Kimberley district of Western Australia. The Nerrima Dome has been mapped at the surface in Permian sediments and is a complex structure. It was desired to determine if the dome existed at depth and, if not, the structure at depth, with a view to locating a site for a deep drilling test. The target beds for such a test are Devonian and/or Ordovician sediments over which the Permian sediments are believed to lie unconformably. Reflection methods were tried and proved unsuccessful and the survey was carried out using refraction methods. Although the structure underlying the dome has not been clearly shown, the refraction method has indicated that it is complex and does not conform with the domal structure at the surface. There appears to be a major unconformity at comparatively shallow depth (2000 ft). The deep structure (7000 ft) although apparently less complex than that immediately below the unconformity, also bears no obvious relation to structure at surface. The results so far obtained are reasonably conclusive in showing that no simple dome-like structure of large magnitude exists under the Nerrima Dome.

The seismic survey extending over the Poole Range and Price's Creek areas and the Pinnacle Fault, near the north-eastern boundary of the Fitzroy Basin. The survey was corducted during the winter of 1953. The Poole Range Dome has been mapped in outcropping rocks of Permian age, but its western closure is notcertain. It is at the south-eastern end of a line of anticlinal folding which includes the St. George Range Dome and Nerrima Dome. The target beds for an oil test bore would be the Devonian and/or Ordovician rocks, which crop out on tbe north-eastern side of the Pinracle Fault, ard over which the Permian rocks of the Poole Range are believed to lie unconformably. The seismic results indicate a thick section of sediments on the south-western side of the Pinnacle Fault and show a fair defree of conformity between shallow and deep reflections on the northern flank of the dome. Further investigation was made in 1954 around the flanks of the dome, to determine whether or not the domal structure persists at depth, but the interpretation of the results of the 1954 survey is not yet complete. The Ordovician roeks on tbe northeastern side of the Pinnacle fault are shown to have a probable unexposed thickness of about 900 feet.
