Seismic tomography of Tasmania: data processing report

During the TASGO Project in 1995, offshore deep seismic reflection profiles were recorded by AGSO?s R/V Rig Seismic along a series of traverses around Tasmania totalling 1758 km in length. Thirty-three portable AGSO seismic recording systems and six University of Tasmania Observatory fixed stations operated continuously onshore during this survey recording seismic arrivals from the ship?s air-guns. They  provided wide-angle and refraction data with a range of source-receiver distances and azimuths. The arrivals have travel paths which pass through the major tectonic elements of Tasmania, and penetrate to below the crust-mantle boundary. They form a substantial new data set for imaging the detailed two-dimensional structure (when combined with the reflection profiles), and the regional three-dimensional structure of the State using tomographic techniques.This record documents the procedures used for processing and displaying the data and the structure of the archived data. The initial processing procedures were different for the analogue data and the digital data. The final processing, signal enhancement and display are common to both types of data.

This GSNSW Exploration NSW Area A3 Bancannia Trough potassium grid geodetic is an airborne-derived radiometric potassium window countrate grid for the NSW DMR, Discovery 2000, 1994-95, AREA A3, Bancannia Trough survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This GSNSW Exploration NSW Area A3 Bancannia Trough potassium grid geodetic radiometric potassium window countrate grid has a cell size of 0.00063 degrees (approximately 65m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 21000 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Georgina NE, NT, 2002 (P1022), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Georgina, NT, 2002 survey were acquired in 2002 by the NT Government, and consisted of 108159 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Australia's uranium resources, geology and development of deposits

Virtually all of Australia's significant uranium deposits were discovered between 1969 and 1980 during the period of high expenditures on exploration for this commodity. This was followed by a long period of low exploration expenditures from 1982 onwards, during which only one deposit (Kintyre) was discovered. Estimates of Australia's uranium resources continued to increase after 1982 only because of on-going delineation of resources at the known deposits.
Australia's uranium resources at December 2000, within the Reasonably Assured Resources (RAR) category recoverable at US$40/kg U, were estimated by AGSO - Geoscience Australia to be 654 000t U. These resources are more than any other country has reported, to date, in this category. Most of these resources are in six deposits:

Olympic Dam (South Australia)
Ranger, Jabiluka, Koongarra in the Alligator Rivers region (Northern Territory)
Kintyre and Yeelirrie (Western Australia).

Australia has the world's largest (29%) resources in RAR recoverable at &#8804;US$80/kg U (includes resources in &#8804;US$40 category) with 667 000t U in this category. According to uranium resource figures published by the mining companies (as distinct from the OECD/NEA and IAEA resource categories defined in Appendix 1), more than 80% of Australia's uranium resources occur in two main types of deposits and about 97% are in four types of deposits:

Breccia complex deposits contain about 65% of Australia's total uranium resources and nearly all of these resources are at Olympic Dam, which is the world's largest uranium deposit.
Unconformity-related deposits account for about 20% of Australia's total resources, mainly in the Alligator Rivers field (Ranger, Jabiluka, Koongarra), and in one deposit in the Rudall Province, Western Australia (Kintyre).
Sandstone uranium deposits account for about 7% of Australia's total resources, mainly in the Frome Embayment field, South Australia (Beverley, Honeymoon, East Kalkaroo, Goulds Dam) and the Westmoreland area, Queensland (Redtree, Junnagunna, Huarabagoo). Other significant sandstone type deposits include Manyingee, Mulga Rock and Oobagooma in Western Australia, and Angela in Northern Territory.
Surficial (calcrete) deposits have about 5% of Australia's resources, most of which are in the world class Yeelirrie deposit. Other calcrete deposits include Lake Way, Lake Maitland and Centipede (Western Australia).

Other types of uranium deposits in Australia include metasomatite deposits (Valhalla, Skal and Anderson's Lode, Queensland) with approximately 1.5% of Australia's total uranium resources. Australia has only small resources within metamorphic (remnant resources at Mary Kathleen, Queensland), volcanic (Ben Lomond, Maureen, Queensland) and intrusive deposits (Crocker Well, Mount Victoria, South Australia). Australia has no significant deposits of the quartz-pebble conglomerate type, vein type and collapse breccia pipe type.

Electrical Conductivity Structure Derived from Magnetotelluric Data in the South-Eastern Mount Isa Region

Geoscience Australia in partnership with State and Territory Geological Surveys has applied the magnetotelluric (MT) technique to image Australia’s resistivity structure over the last decade. As part of the Mount Isa Geophysics Initiative program, MT data were collected at 138 sites along a 690 km transect in the South-Eastern Mount Isa. Geoscience Australia undertook data analysis and data inversion to create the most plausible resistivity model. 2D and 3D data modelling were undertaken using well-verified algorithms. The 2D and 3D resistivity models derived from the MT data show some consistent features that are likely to be the real subsurface geology. The near-surface conductive layer resolved by the MT models represents the Carpentaria and Eromanga sedimentary basins reasonably well, in terms of resistivity and thickness. The MT models reveal a predominant crustal-scale conductor, which is interpreted to be part of the Carpentaria Conductivity Anomaly. A number of localised zones of enhanced conductivity are also detected within the crust. These conductors correspond to known major faults identified by seismic and geological data. One of the faults, i.e. the Cork Fault, marks the tectonic boundary between the Mount Isa terrane and the Thomson Orogen. The geometries of these conductive bodies suggest that the enhanced conductivity may be caused by deformation or mineralisation associated with faulting. Some of these faults linking into the middle and lower crust are considered as the primary factors in the partitioning of mineralisation in the region.
Results from the magnetotelluric data provide new insights into the understanding of the complex crustal structure where little geological history is known.
