AUSGeoid98 v.1.0 data files:  (sk54-09)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

GSWA South Officer 1 Jubilee Uranium Grid Geodetic

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 radiometric uranium grid has a cell size of 0.00042 degrees (approximately 44m) and shows uranium element concentration of the Jubilee, WA, 2010 (South Officer 1) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 184296 line-kilometres of data at 200m line spacing and 50m terrain clearance.

SA Exploration Initiative 1995 - Area B17 B (P705), 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 SA Exploration Initiative 1995 - Area B17 survey were acquired in 1995 by the SA Government, and consisted of 36821 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.

Australian Western & Northern Margins Panorama Chart No. 28a & 28b

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.

St Arnaud total count grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This St Arnaud total count grid geodetic has a cell size of 0.00042 degrees (approximately 42m) and shows the terrestrial dose rate of the St Arnaud Infill merge, 1990. The data used to produce this grid was acquired in 1990 by the VIC Government, and consisted of 18970 line-kilometres of data at a line spacing between 200m and 400m, and 100m terrain clearance.

Summary Of Data And Results Carnarvon Basin, Western Australia Wandagee Ridge Seismic Survey Salt Marsh Seismic Survey Of West Australian Petroleum Pty Limited

A reconnaissance seismograph survey of the Wandagee area of the Carnarvon Basin (see Figs 1, 2) was carried out by Geophysical Service International, Party 621, for West Australian Petroleum Pty Limited between November, 1961 and February, 1962. The project area falls within Permit to Explore 28H.
The survey was designed to map the structure and the stratigraphy of the Wandagee Ridge (South) area of the Carnarvon Basin. The survey commenced on 9th November, 1961, and terminated on 7th February, 1962, after covering 115 1/2 miles of reflection traverse and 33 1/.3 miles of refraction traverse.
The results of these reflection and refraction surveys were combined with other geophysical data to produce an overall interpretation.
There are two distinct areas of interest separated by the Wandagee Fault. The Wandagee Fault is a large down-to-the-east normal fault in the pre-Cretaceous section, with reverse movement occurring later than the Cretaceous. Devonian rocks are present at shallow depth on the west side of the fault, but there are probably 10,000 feet of Permian on the east side.
East of the Wandagee Fault the north-south trending Quail Anticline was partly delineated. It is suggested that this anticline closes in Permian and perhaps in Carboniferous Devonian horizons.
The geoIhysical operation undertaken in the Wandagee Ridge area, Carnarvon Basin, Western Australia, was subsidized under the Petroleum Search Subsidy Act 1959.

The effect of uncertainty in earthquake fault parameters on the maximum wave height from a tsunami propagation model

We have run several thousand tsunami propagation models in order to determine the effect of uncertainty in an earthquake's rupture parameters (specifically strike, dip, rake, depth and magnitude) on the maximum wave height of the tsunami that it creates. We have shown that even for the simple case of a tsunami propagating over flat bathymetry, the Coefficient of Variation (CoV) of the maximum wave height was a complex function of the choice of rupture parameter, distance and azimuth. For example, if the strike of the fault was varied, the CoV was at maximum on either side of the tsunami beam, but if the dip was varied the CoV was at a maximum along the strike of the rupture. We then created maps of the skewness of the distribution of the maximum wave height. They also showed a complex dependence on the choice of the rupture parameter, azimuth and distance. Finally, we have examined the effect of a realistic bathymetry on CoV and skewness by mapping them for three hypothetical earthquakes on different types of subduction zones (Kermadec, Java and the Solomon Islands). These examples showed that the areas of shallow bathymetry in either the local or far field can also make a significant difference to both the CoV and skewness of the distribution of maximum tsunami wave heights at a point.

HyLogger - Providing New Insights to IOCG Deposits

As part of the HyLogger campaigns conducted by Primary Industries and Resources South Australia (PIRSA) in 2003-04 and 2004-05 a selection of signature diamond cored drill holes from the Olympic Domain IOCG province in South Australia were scanned to determine spatial patterns in their alteration mineralogy. Using Emmie Bluff SAE6 as a type hole it was empirically determined that Cu mineralisation can be spatially related to white mica chemistry and the distribution of Fe/Mg chlorite. These trends were found to be transferable to other sites. The PowerPoint presentation provides summary diagrams for a number of these drill holes.

Late Triassic conodont and palynomorph biostratigraphy and conodont thermal maturation, North West Shelf, Australia

Late Triassic (Norian-Rhaetian) conodonts recovered from borecores and sea-bottom dredge samples on the North West Shelf off Western Australia are assigned to the Metapolygnathus primitius, Epigondolella triangularis, E. spiculata, E. postera, E. bidentata, Misikella hernsteini, and M. posthernsteini Zones.  Based on previous studies, particularly from North America, these conodont zones can be used to tie with the standard Triassic ammonite zonation. The present record therefore provides the first set of chronologie anchor points for dating the co-occurring dinocyst assemblages and spore-pollen floras from the North West Shelf. Our conodont data show that the Hebecysta (al. Heibergella) balmei, Rhaetogonyaulax (al. Shublikodinium) wigginsii, and Wanneria (al. Suessia) listeri dinocyst zones are younger than suggested previously, and that some zonal ranges overlap. We conclude that further detailed palynological and conodont studies are urgently needed to resolve these problems and extend conodont age control into the early Late Triassic (Carnian) and the Middle Triassic. Key wells investigated include Ashmore Reef 1, Mt. Ashmore 1B, and Sahul Shoals 1.  Conodont thermai maturation data indicate a very low thermal gradient on the Ashmore Platform near the shelf margin, but a more normal thermal gradient on the Sahul Platform and a high heat flow in the onshore Bonaparte Basin.

Palynological analysis of infill samples for selected wells in the South Australian section of the Pedirka Basin.

Palynology preparations from 50 samples from several key wells in the South Australian section of the Pedirka Basin were examined for Geoscience Australia. The sampling was done by Carey Hannaford under inspection number 5358 (see table 1 for sample listing). All resulting slides and remaining residue have been submitted to government. The samples were analysed quantitatively with the first 200 specimens in each sample counted and subsequent species simply recorded as present. In this summary report, the results are provided in tabulated form only. Details of the palynomorph assemblages are recorded on StrataBugs distribution charts, with each taxon expressed as a percentage of the entire assemblage (Appendix B). From this information, assignments are made to the palynostratigraphic scheme of Price (1997), as shown in Figures 1 and 2 and summarised in Appendix A.
Wells included are: Erabena-1, Macumba-1, Mokari-1, Oolarinna-1, Pandieburra-1, Poolowanna-1, Poolowanna-2, Walkandi-1.
