Dubbo Detail NSW 1991 (P569), radiometric line data, AWAGS levelled

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 Dubbo Detail NSW 1991 (P569), radiometric line data, AWAGS levelled were acquired in 1991 by the NSW Government, and consisted of 63636 line-kilometres of data at a line spacing between 200m and 400m, and 100m 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.

The 2018 National Seismic Hazard Assessment: Model overview

Geoscience Australia, together with contributors from the wider Australian seismology community, has produced a National Seismic Hazard Assessment (NSHA18) that is intended as an update to the 2012 National Seismic Hazard Maps (NSHM12; Burbidge, 2012; Leonard et al., 2013).  This Geoscience Australia Record provides an overview of the development of the NSHA18.  Time-independent, mean seismic design values are calculated on Standards Australia’s AS1170.4 Soil Class Be (at VS30=760 m/s) for the horizontal peak ground acceleration (PGA) and for the geometric mean of the spectral accelerations, Sa(T), for T = 0.1, 0.2, 0.3, 0.5, 1.0, 2.0 and 4.0 s over a 15-km national grid spacing.  Hazard curves and uniform hazard spectra are also calculated for key localities.  Maps of PGA, in addition to Sa(0.2 s) and Sa(1.0 s) and for a 10% probability of exceedance in 50 years (Figure A).  Additional maps and seismic hazard products are provided in a separate Geoscience Australia Record (Allen, 2018).
The NSHA18 update yields many important advances over its predecessors, including:
-   the calculation in a full probabilistic framework (Cornell, 1968) using the Global Earthquake Model Foundation’s OpenQuake-engine (Pagani et al., 2014);
-   the consistent expression of earthquake magnitudes in terms of moment magnitude, MW;
-   inclusion of a national fault-source model based on the Australian Neotectonic Features database (Clark et al., 2016);
-   the inclusion of epistemic (i.e. modelling) uncertainty:
-   through the use of multiple alternative source models;
-   on magnitude-recurrence distributions;
-   fault recurrence and clustering models;
-   on maximum earthquake magnitudes for both fault and area sources through an expert elicitation workshop; and
-   the use of modern ground-motion models, capturing the epistemic uncertainty on ground motion through an expert elicitation workshop.

Australia's Identified Mineral Resources 2005

Geoscience Australia provides information on the nation's future capacity to produce mineral resources. Australia's Identified Mineral Resources is an annual nation-wide assessment of Australia's ore reserves and mineral resources. All major and a number of minor mineral commodities mined in Australia are assessed.
Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2004 - bauxite, black coal, copper, gold, iron ore, ilmenite, lead, manganese, rare earth elements, tantalum, tin, uranium and zinc. EDR of cobalt, diamonds (both gem and industrial), lithium, phosphate, rutile, silver, tungsten and zircon decreased during the year. EDR for brown coal, magnesite, molybdenum, nickel, niobium, platinum group metals, shale oil, and vanadium remained at levels similar to those reported in 2003.
Increases in EDR were due to on-going drilling and evaluation of known deposits resulting in the transfer (re-assessment) of resources from inferred or sub-economic categories into EDR, and discoveries of new deposits or extensions of known deposits. Newly delineated resources of 1 256 t added to gold's total national inventory, with growth in all east coast mainland states and South Australia. A few mining companies re-estimated ore reserves and mineral resources more conservatively for some commodities to comply with the requirements of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code).

Regolith in the Central Gawler, through and through

The Central Gawler Gold Province is poorly known and poorly explored, principally because of the extensive development of regolith. CRC LEME is collaborating with Geoscience Australia and the Minerals Resources Group in the South Australian Department of Primary Industry and Resources to reduce the risk attached to exploration through the regolith in this terrain. We have integrated the interpretation of geological, geophysical, and calcrete geochemical data at known prospects in order to develop a strategy for generating ranked drilling targets.
This ranking strategy carries the assumption that Au anomalies in calcrete formed in in-situ regolith materials are associated with Au mineralisation at depth. However, this assumption ignores the possibility that Au is moving laterally through the regolith in groundwater. It has been established that groundwater is mobilising significant quantities of Au in areas of the central Gawler Craton. Au may be precipitated within the regolith when the chemical or physical conditions governing mobilisation change. This process could generate "false" Au anomalies.
Our research suggests that regolith geochemistry (surface and sub-surface) should be interpreted against the groundwater chemistry and an understanding of groundwater flow paths. Whereas groundwater chemistry can only be established by assaying samples from drillholes, groundwater flow paths can be mapped using a combination of geology and geophysics. At prospect scale, these results can be used as vectors to primary mineralisation, thereby refining targeting strategies.
