  • Geoscience Australia in collaboration with the Geological Survey of NSW acquired the Yathong Trough Deep Crustal Seismic Survey in 2013. The survey involved the acquisition of seismic reflection and gravity data along two traverses, 13GA-YT1 (98km) and 13GA-YT2 (132km) near Hillston, NSW. The purpose of the survey was to acquire new data to better understand the regional geology and major structured of the Yathong Trough within the Darling Basin, NSW. Funding was from the Geological Survey NSW through the New Frontiers Initative. Raw data for this survey are available on request from clientservices@ga.gov.au

  • The 2005 Tanami Seismic Survey was carried out from May to July for a research consortium consisting of Geoscience Australia, Geological Survey of Western Australia, Northern Territory Geological Survey, Newmont Mining and Tanami Gold. The Australian National Seismic Imaging Resource (ANSIR) was responsible for seismic data acquisition, as well as for field QC and preliminary in-field processing. The survey consisted of 720 line km along four regional deep seismic traverses, aimed at providing orthogonal three-dimensional control on the regional fault geometry.

  • <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>

  • 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

  • Terrex Seismic was contracted by the Australian National Seismic Imaging Resource (ANSIR) to conduct the Department of Minerals and Resources (DMR NSW) Darling Basin 2004 Seismic Survey in New South Wales. Recording commenced on the 15th June 2004 on line DMR04-1 and was completed by the 1st July 2004. The survey operation covered areas north-east and north-west of Ivanhoe, and north of Wilcannia. Three 2D seismic lines, totalling 133.86 kilometres, were surveyed at a 30m station interval. Raw data for this survey are available on request from clientservices@ga.gov.au

  • The preliminary investigation was made when the Bureaut s seismic party was held up by flooded rivers, while on its way t o Christmas Creek in May, 1954. Results show that the seismic aethod is applicable to the Broome area, and that a sedimentary section of the order of 12,500 feet exists. They further show that a syncline and anticline not known from the surface geology may possibly exist at depth.

  • On 12th July 1960, a velocity survey of the A.A.O. Pickanjinnie No. 1 bore was made by the Bureau of Mineral Resources. The bore had been drilled to a depth of 5218 ft and was surveyed to the bottom. The average velocities for the Mesozoic rocks and the Timbury Hills Formation are similar to those measured in the Timbury Hill No. 2 bore. However, it seems impossible to correlate individual units within the Mesozoic sequence according to their velocity.

  • Following a month of preliminary experimental seismic work in the latter part.of 1964 the Bureau of Mineral Resources carried out a reconnaissance seismic survey of the southern part of the Georgina Basin, mainly in the Northern Territory, from April to October 1965. In most areas reflections proved very difficult to obtain. A number of different techniques were tried, including various shot andgeophone pattern arrangements, noise testing,collinear offset shooting, airshooting and multiple coverage, but no technique was found which was generally successful in providing useful reflections. The seismic results tended to confirm gravity indications that there is a shelf area between BMR 12 Bore and Tobermory and provided no indications that there are deep Palaeozoic troughs similar to the Toko -Syncline in the survey area.

  • <p>Geoscience Australia conducted a seismic, gravity and aeromagnetic survey in Central Australia, Northern Territory from July to November, 1985. The objectives of this multidisclipinary experiment were to investigate the structural evolution of the lithosphere in the Central Australian region with emphasis on the formation of the Ngalia and Amadeus Basins, and secondly to aid in the evaluation of the petroleum prospectivity of the basins. 486 km of six-twelve fold common mid-point (CMP) seismic reflection data were collected, from four traverses.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74968</b>

  • The Bureau of Mineral Resources conducted a seismic reflection survey of a small area near Broome, W.A., during 1954 and 1955. It was part of a general investigation of the Canning Basin and was aimed at determining the distribution of sediments south of the Fenton Fault. The seismic work indicated a sedimentary thickness of at least 6000 feet, and probably as much as 10,000 feet could be expected. It also showed that the subsurface formations are probably folded and faulted.
