Larrimah, Daly Waters, NT, 1987 (P527), 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 Larrimah, Daly Waters, NT, 1987 survey were acquired in 1987 by the NT Government, and consisted of 29760 line-kilometres of data at 1500m line spacing and 150m 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.

Carbonatite-related rare earth element mineral potential maps

Maps showing the potential for carbonatite-related rare earth element (REE) mineral systems in Australia. Each of the mineral potential maps is a synthesis of three or four component layers. Model 1 integrates three components: sources of metals, energy drivers, and lithospheric architecture. Model 2 integrates four components: sources of metals, energy drivers, lithospheric architecture, and ore deposition. Both models use a hybrid data-driven and knowledge driven methodology to produce the final mineral potential map for the mineral system. An uncertainty map is provided in conjunction with the mineral potential map for Model 2 that represents the availability of data coverage over Australia for the selected combination of input maps. Uncertainty values range between 0 and 1, with higher uncertainty values being located in areas where more input maps are missing data or have unknown values. An assessment criteria table is provided and contains information on the map creation.

AUSGeoid98 v.1.0 data files:  (sc55-15)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Geology of the Amadeus Basin, central Australia

The area mapped lies in the southern part of the Northern Territory and in Western Australia between latitudes 23 Â°S. and 26Â°S. and longitudes 127Â°30'E. and 136Â°30'E. (Pis 45, 46). It is 575 miles long and 205 miles wide and occupies 118,000 square miles. Sedimentary rocks of the Amadeus Basin crop out over an area of about 60,000 square miles; the remainder of the area is underlain by basement rocks or sedimentary rocks of the Great Artesian Basin in the southeast and of the Canning Basin in the west. The mapping of the Amadeus Basin by the Bureau of Mineral Resources was completed in 1964. The basin was mapped in stages: Joklik and others in 1949-51; Prichard, Quinlan, and others in 1956; Wells, Forman, Ranford, and others in 1960-64. The results of these surveys have been published by Joklik (1955), Prichard, Quinlan (1962), Wells et al. (1964, 1965, 1966, 1967), Ranford et al. (1966), Forman (1966c), and Forman et al. (1967). This Bulletin is a summary and synthesis of the entire survey. Figure 1 shows the areas covered by the various publications; previous investigations have been described in detail in them, and only an outline of earlier work in the region is given here.

Geodynamic Synthesis of the Phanerozoic of eastern Australia. Second Edition

This report presents the second edition of a 'Geodynamic Synthesis of the Phanerozoic of Eastern Australia', the first edition being published in 2009. The original Record was undertaken with two aims: (1) to better understand the tectonic and geodynamic setting of known mineral deposits within eastern Australia, and (2) to provide a predictive capability for extending potential regions of known mineralisation and delineating regions with potential for new mineral styles and commodities. This was achieved by synthesising geological and metallogenic data on a regional, largely orogenic, basis. This allowed the identification of geological and metallogenic events and geodynamic cycles, and the production of regional geological syntheses and accompanying time-space-event plots. These regional syntheses were used to produce an interpreted geological, metallogenic and geodynamic synthesis of eastern Australia. This synthesis provided the geodynamic framework to constrain known mineralisation and allow a predictive capability for potential new mineralisation. 
Since the first edition, significant new geological information and tectonic models have appeared for most parts of eastern Australia, along with the definition and/or redefinition of many geological provinces, sub-provinces and igneous associations. This new information, tectonic models and names have been incorporated into this second edition.

Preliminary report on geophysical survey of the Janina lease, Barrona county, New South Wales

Gravimetric and magnetic investigations have been carried out by the Bureau during October and November 1950 in order to find favourable locations for artesian water bores on lease No. 5893, known as Janina and situated in Barrona County. The geophysical survey was requested because two bores recently drilled on the lease failed to produce artesian water, although artesian water bores previously completed in the area adjacent to Janina lease proved the existence of certain aquifers yielding sufficient quantities of good water. Results of the geophysical fieldwork as correlated with data obtained from boring indicated a gentle uplift of basement rocks and water bearing strata, trending from NE to SW and occupying more or less all of the center part of Janina lease. No indications could be derived however from geophysical data as to a relatively steep uplift of basement rocks in the vicinity of bore No. 8153. Hard strata of sandrock and quartzite encountered by this bore at approximately 470 to 480 feet therefore must be classified as probably being of local character. Further drilling operations for suitable water supply naturally should avoid the aforementioned structural high, which is apparent from both boring data and gravitational work.

A national-scale vulnerability assessment of seawater intrusion: literature review, data review and method development

Fresh water stored in Australian coastal aquifers constitutes an important resource for humans and the natural environment. However, many Australian coastal aquifers are vulnerable to seawater intrusion, which is the landward encroachment of seawater into coastal aquifers. This report is one technical report in the National Seawater Intrusion Project. The overarching project aims to assess the current and future vulnerability of Australian coastal aquifers to seawater intrusion associated with groundwater extraction and sea level rise.
This report is the literature review, data review and method development component of the project. It analyses existing literature and data associated with seawater intrusion in Australia and internationally. It also develops a method to be implemented in subsequent phases of the project to assess seawater intrusion nationally.

Basin Biozonation and Stratigraphic Chart - Bowen, Gunnedah and Surat Basins  Chart No. 10

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

Research Cruise Proposal : Light Hydrocarbon Geochemistry of the Bass, Otway, Stansbury and Gippsland Basins, and Torquay Sub-basin, Southeastern Australia : Project 9131.20

The measurement of the concentrations and molecular compositions of light hydrocarbon gases within the water column overlying offshore sedimentary basins can provide, under suitable circumstances, significant information on hydrocarbon source rock maturity and/or type, and the most likely locations for petroleum accumulation within basins. These measurements are usually made using a hydrocarbon 'sniffer', which comprises a submersible fish which is towed near the seafloor, and from which water is pumped to the surface and continuously analysed via gas chromatography. Compared with overseas, relatively few 'sniffer' surveys have been carried out around Australia, and hence the applicability and usefullness of this technique to the Australian situation is as yet undetermined.
As a continuation of its geochemical research program, the Division of Marine Geosciences and Petroleum Geology (Australian Bureau of Mineral Resources) will conduct a co-operative geochemical research survey withTransglobal Exploration and Geoscience (TEG) of Leucadia, California, USA, in southeastern Australia between February 1 and March 2, 1989. The cruise will be of 30 days duration and will involve work in the Gippsland, Bass, Otway and Stansbury Basins and the Torquay Sub-basin. A detailed proprietary program will be carried out in the Bass and Stansbury Basins in co-operation with Amoco Production Company. Two regional lines will be run from the Torquay Sub-basin, across the Cape Otway-King Island High, to the Crayfish Platform in the west of the Otway Basin (see Fig. 2). Regional lines will also be run in the Gippsland Basin, with an additional detailed program over several known oil and/or gas accumulations. In addition to the water column geochemistry, a limited sampling program will investigate the light hydrocarbon geochemistry of sediments over known oil and gas fieldsin the Gippsland Basin.
