Birrindudu, WA, 1991 (wa241mr_b) (P871), 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 Balgo-West Tanami-Billiluna-Birrindudu merge, 1991-2002 survey were acquired in 1991 by the WA Government, and consisted of 176812 line-kilometres of data at a line spacing between 200m and 200m, and 60m 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.

Aquifer remediation in Australia - current regulatory guidelines, evaluation of treatment technologies, and future directions (panel discussion)

Aquifer remediation is becoming increasingly important in Australia owing to the tightening up of environmental and health standards, and increasing stresses on groundwater resources. A panel discussion at the conference  Aquifers at Risk focussed on current regulatory guidelines for remediation in Australia, the evaluation of treatment technologies, and on likely future directions. Current issues were highlighted and comparisons drawn with the situation in the United States.

Otway Basin: Regional Seismic Horizon Maps for the Onshore Areas at the 1:500 000

During the period 1991-94, a co-operative study of the early development of the Otway' Basin was
undertaken as part of a National Geoscience Mapping Accord project. The partners in the project
were the Australian Geological Survey Organisation (AGSO), the Geological Survey of Victoria
(GSV), the Department of Mines and Energy, South Australia (MESA), and the Victorian Institute
of Earth and Planetary Sciences (VIEPS) at Monash and La Trobe Universities. As part of the
project, four subsurface horizons were mapped across the onshore parts of the basin using
exploration industry and AGSO seismic data. MESA undertook mapping in the South Australian
sector of the basin, GSV in the central (western Victorian) part of the basin, and AGSO and VIEPS
in the eastern part of the basin. This is the first time such mapping has been published on a basinwide
scale in the Otway Basin.
This Record accompanies a folio of ten 1:500 000 scale maps compiled by AGSO from the data
provided by NGMA partners from the western, central and eastern parts of the onshore basin. Four
of these maps are presented as two-way times (in milliseconds) to four mega-sequence boundaries
together with interpreted structural information. The four mega-sequence boundaries are: -
1) - base Wangerrip Group,
2) - top Eumeralla Formation,
3) - top Crayfish Group,
and 4) - top Palaeozoic basement.
Time thickness (isochron) maps (in milliseconds two-way time) for the Crayfish Group, the
Eumeralla Formation and the Sherbrook Group, complete the horizon mapping. Also included are
maps of seismic line information and tectonic elements, and geophysical maps of gravity and
magnetic data. The maps are designed to improve the overall understanding of Otway Basin
subsurface geometry and tectonic evolution as a guide to possible hydrocarbon resources.

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.

Geothermal gradients and heat flow in Australian sedimentary basins

Geothermal gradients in Australian sedimentary basins have been calculated from data obtained from water bores in the Great Artesian Basin and oil exploration wells. The data are subject to several types of systematic error, but statistical trends have been extracted, using values of thermal conductivity obtained from sediment compaction models. Estimates of heat flow from the Great Artesian Basin are consistent with the configuration of the major aquifer systems. Oil well data confirm the regional trends obtained from previous investigations, but previously recognised anomalies in southeast Australia are no longer evident. Temperatures at a depth of 40 km range from 320Â°C to 380Â°C for the Precambrian terrain and from 470Â°C to 550Â°C for the Phanerozoic . These results are modified by sediment cover. A 1 km thickness causes additional heating, with temperatures raised by 16-40Â°C.

An Empirical Fatality Model for Indonesia Based on a Bayesian Approach

Many earthquakes in Indonesia have caused a large number of fatalities. Disaster risk-reduction of fatalities requires a representative fatality model derived from fatality data caused by historical earthquakes in Indonesia. We develop an empirical fatality model for Indonesia by relating macroseismic intensity to fatality rate using compiled subdistrict level fatality rate data and numerically simulated ground shaking intensity for four recent damaging events. The fatality rate data are compiled by collecting population and fatality statistics of the regions impacted by the selected events. The ground shaking intensity is numerically estimated by incorporating a finite fault model of each event and local site conditions approximated by topographically-based site amplifications. The macroseismic intensity  distribution of each event is generated by using ShakeMap software with a selected pair of ground motion predictive equation (GMPE) and ground motion to intensity conversion equation (GMICE). The developed fatality model is a Bayesian generalized linear model where the fatality rate is assumed to follow a mixture of a Bernoulli and a gamma distribution. The probability of zero fatality rate and the mean non-zero fatality rate is linked to a linear function of shaking intensity by the logit and the log link functions, respectively. We estimate posterior distribution of the parameters of the model based on the Hamilton Monte Carlo algorithm. For validation of the developed model we calculate fatalities of the past events from the EXPO-CAT catalog and compare the estimates with the EXPO-CAT fatality records. While the developed fatality model can provide an estimate of the range of fatalities for future events it needs on-going refinement by incorporation of additional fatality rate data from past and future events.

Application of magnetic resonance data for groundwater prospectivity in the Fitzroy Basin, Western Australia

In the Fitzroy Basin of Western Australia, both ground and borehole Nuclear Magnetic Resonance (NMR) techniques have been applied during a groundwater prospectivity assessment of the Cenozoic sediments, and the Palaeozoic and Mesozoic sandstone aquifers. Ground magnetic resonance (GMR) data was acquired at ten sites from the within the basin and the data was inverted to obtain estimates of the one-dimensional water content for the top 100m. Where these sites were co-located with boreholes, the results were consistent with inverted borehole NMR data and other litho-stratigraphic information although with a reduced horizontal resolution.
Both the GMR and borehole data suggest that the Palaeozoic Grant Group and Poole Sandstone have high water content and have the potential to be highly productive aquifers. Furthermore GMR can be used estimate the depth to water table for unconfined aquifer, using 5 volume % as the threshold for saturated zone.
