Sydney, NSW, 1990 (P576), 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 Sydney, NSW, 1990 survey were acquired in 1989 by the NSW Government, and consisted of 19364 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.

AUSGeoid98 v.1.0 data files:  (si53-05)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

Macro-scale targeting of magmatic-related uranium mineral systems

Uranium-rich igneous rocks are recognised as an important source of metals in uranium mineral systems. Magmatic-related uranium mineralisation may be orthomagmatic in origin, forming via favourable igneous processes, or may result from the exsolution of uranium-rich fluids from particular magmas. Additionally, it is recognised that igneous rocks also may contribute directly to basin-related uranium mineral systems as a metal source. Thus, mapping of the distribution of uranium in igneous rocks has the potential to highlight prospective regions for uranium mineralisation at a macro-scale.
Geoscience Australia has produced a series of three digital maps showing the uranium content of igneous rocks across Australia, drawing together geochemical and geological datasets from disparate open file sources. Map 1 shows the uranium concentration in whole rock geochemical analyses plotted as point data on a background of igneous rock type, which itself is derived from Geoscience Australia's 1:1 000 000 national surface geology map. Map 2 integrates these datasets, and shows the average uranium content of all intersecting geochemical data point for outcropping individual igneous rock units. In Map 3, a similar approach is employed in mapping the average uranium content of igneous rocks occurring under cover, using interpreted solid geology coverages. Combined, these maps provide a comprehensive picture of the province-scale trends in igneous uranium content across the continent.
Using an applied knowledge of processes leading to uranium concentration in magmatic systems, igneous rocks exhibiting a favourable combination of factors are able to be identified for further analysis of prospectivity for uranium mineral systems.

The late Cainozoic evolution of the Carpentaria Plains, North Queensland: reply

Wasson (1979) discusses our interpretation and correlation of the fluvial sequence in the Carpentaria Plains (Grimes and Doutch, 1978). His main criticisms are: (1) he considers that we have insufficient stratigraphic data to substantiate our division of the fans sequence into five stages and to support our correlation of these stages with the sequence in the southern plains; (2) he criticises the brevity of our discussion of climatic and sea levels controls on the evolution of the fans and our apparent exclusion of tectonic effects, and would seem to consider that the shifts in the depositional areas of the fans are not related to environmental changes; (3) in view of his doubts concerning the above points, he considers that the regional correlations which we suggested are suspect and that the fans provide a poor basis for attempting such correlations. We will discuss these points in sequence.

The sustainability of mineral use

The sustainability of mineral use, like the definition of sustainable consumption patterns, is a function both of the availability of resources and of the environmental impacts of resource use.  The environmental impacts are a major factor in modifying consumption patterns and therefore in moderating demand.  In spite of a number of factors tending to moderate demand, global demand is likely to continue to increase for the foreseeable future, mainly as a result of the continuing increase in global population which is unlikely to be stabilised before the end of the 21st century.  Discussion of the relationship between population, resource use and the environment, using the concepts of the support square and per capita resource use, illustrates the unsustainability of present demand trends and of the consumption patterns that cause them.  It is therefore important that strategies to maintain supply be linked to effective strategies to move to sustainable consumption patterns.  The capacity to meet the demand for minerals is also being reduced, as the global population increases, by concerns about environmental impacts and by competing land uses. It is therefore important that minerals issues should be part of the integrated approach to land management promoted in Agenda 21.  Sustainability is a long-term concept involving inter-generational equity, and the time scales are beyond those of the reasonably foreseeable future.  It is not possible to see beyond a definable horizon of sustainability and the  precautionary principle is therefore important for global management strategies.  The paper identifies a number of steps at the global level which can assist in the management of resources and of environmental impacts during the period of transition to more sustainable consumption patterns.  These relate to improvements in knowledge (1) for assessing the impacts of mineral use in the industrial system as an essential basis for improving efficiency and determining optimum consumption patterns; (2) for monitoring the chemical health of the global land surface; and (3) for assessing resource potential in ways that can be integrated with other land use information, and that can be used to push back the horizon of sustainability.

Australian National Inorganic Geochemistry Data Collection

Data in the GEOCHEM database comprises inorganic geochemical analytical data and associated metadata. Geochemical data comprises concentration data (value, error, unit of measure) measured on a range of analytical instruments, for a range of elements of the periodic table. Associated metadata includes information on analytical techniques, analytical methodology, laboratory, analysts, date of analysis, detection limits, accuracy, and precision. The GEOCHEM database also records results for reference standards. Data is specifically for rocks, soils and other unconsolidated geological material and does not include oils, gases or water analyses. Geochemical data may be total rock (i.e., whole rock analysed) or for a variety of fractions of the total rock, e.g., various non-total acid digests, mineral separates, differing size fractions. It also includes quantitative to semi-quantitative data from field measurements, such as portable x-ray fluorescence (XRF). It does not include geochemical data for individual minerals. 
Value: Geochemical data underpins much geoscientific study, and is used directly to classify, characterise and understand geological material and its formation. It has direct relevance to understanding the formation of the earth, the continents, and the processes that create and shape the surface we live on. For example, this information is used within: both discovering and the understanding of mineral deposits we depend on; the nature, health and sustainability of the soils we live and farm on; as well as providing input into a range of potential geohazards. 
Scope: The collection includes data from over 60 years of Geoscience Australia (GA) and state/territory partner regional geological projects within Australia, as well as continental-scale and regional geochemical surveys like National Geochemical Survey of Australia (NGSA) and Northern Australia Geochemical Survey (NAGS) (Exploring for the Future- EFTF). It also includes data from other countries that GA has worked with, e.g., Papua New Guinea, Antarctica, Solomon Islands and New Zealand.
