Sir Samuel 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 0.00083 degrees (approximately 87m) and shows uranium element concentration of the Sir Samuel, WA, 1993 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1993 by the WA Government, and consisted of 47075 line-kilometres of data at 400m line spacing and 100m terrain clearance.

SA Exploration Initiative - Area A1, SA., 1993 (P700), 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 - Area A (A1-A7), SA., 1993 survey were acquired in 1992 by the SA Government, and consisted of 330915 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.

Assessing the impacts of tropical cyclones

Tropical Cyclone (TC) Tracy impacted Darwin early on Christmas Day, 1974. The magnitude of damage was such that Tracy remains deeply ingrained in the Australian psyche. Several factors contributed to the widespread damage, including the intensity of the cyclone and construction materials employed in Darwin at the time. Since 1974, the population of Darwin has grown rapidly, from 46,000 in 1974 to nearly 115,000 in 2006. If TC Tracy were to strike Darwin in 2008, the impacts could be catastrophic. 
We perform a validation of Geoscience Australia's Tropical Cyclone Risk Model (TCRM) to assess the impacts TC Tracy would have on the 1974 landscape of Darwin, and compare the impacts to those determined from a post-impact survey. We then apply TCRM to the present-day landscape of Darwin to determine the damage incurred if a cyclone identical to TC Tracy impacted the city in 2008. 
In validating TCRM against the 1974 impact, we find an underestimate of the damage at 36% of replacement cost (RC), compared the survey estimate of 50-60% RC. Some of this deficit can be accounted for through the effects of large debris. Qualitatively, TCRM can spatially replicate the damage inflicted on Darwin by the small cyclone. The northern suburbs suffer the greatest damage, in line with the historical observations. 
For the 2008 scenario, TCRM indicates a nearly 90% reduction in the overall loss (% RC) over the Darwin region. Once again, the spatial nature of the damage is captured well, with the greatest damage incurred close to the eye of the cyclone. Areas that have been developed since 1974 such as Palmerston suffer very little damage due to the small extent of the severe winds. The northern suburbs, rebuilt in the years following TC Tracy, are much more resilient, largely due to the influence of very high building standards put in place between 1975 and 1980.

AUSGeoid98 v.1.0 data files:  (sk52-10)

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.

Lithospheric velocity beneath the Adavale Basin, Queensland, and the character of deep crustal reflections

Along a traverse across the main depression of the Devonian Adavale Basin in western Queensland, lateral variations in lithospheric velocity are predominantly displayed in the upper 15 km of the crust. In this region, Devonian sediments (up to 7 km thick) underlie the Jurassic- Cretaceous Eromanga sequence (up to 2 km thick) with only minor pockets of intervening Permo-Triassic sediments of the Cooper and Galilee Basins.  P-wave velocity in t he sediments ranges from 2.0 to 5.5 km/s.  Underlying the Devonian sediments is a 2- 3 km thick basement transition zone of highly folded, faulted, and sheared rocks, where metamorphic grade increases and weathering decreases with depth, and velocity increases from 5.6 to 5.85 km/s.  Upper crustal basement extends to 24-25 km with velocity increasing from 5.9 km/s below the basement transition zone to 6.4 km/s above a mid-crustal horizon. Multiply refracted phases suggest the velocity gradient of 0.02 - 0.03 k  s/ km in the upper crustal basement is fairly uniform a long the traverse. The increase in mid-crustal velocity from 6.4 to 6.6- 6.7 km/s is a prominent feature of the lithosphere. It marks the upper boundary of the lower crustal reflection zone evident from continuous reflection profiling. Within this zone, the velocity increases to 6.8-7. 1 km/s at the top of the crust/mantle transition zone at a depth of about 35 km.  Neither the mid-crustal velocity horizon nor the Moho varies greatly in depth.  The upper mantle velocity of 8.15 km/s is reached at 38- 40 km depth, the same as that measured on an east - west cross traverse. The preferred interpretation of the lower crustal velocity gradient and reflections is that they arise from extensive lower crustal magma intrusion during the formation of quasi-continental crust and that subsequent thermal events have enabled isostatic readjustment and basin formation in a compressive regime.

Source rock geochemistry of the offshore northern Perth Basin: Regional hydrocarbon prospectivity of the offshore northern Perth Basin

The Australian Petroleum Source Rocks Mapping project is a study aimed at improving our understanding of the petroleum resource potential of Australia’s sedimentary basins. As part of this project, the offshore northern Perth Basin source rock geochemistry and maturity have been assessed. This report characterises the organic richness, kerogen type and thermal maturity of source rocks in the offshore northern Perth Basin based on a compilation of updated and quality controlled publically available total organic carbon (TOC), Rock-Eval pyrolysis, organic petrological and pyrolysis-gas chromatography data. This record is an interpretive report of the geochemical data presented in the offshore northern Perth Basin well folio (Jorgensen et al., 2011). Maps of present-day TOC and present-day HI were created to show the spatial variation in the amount and quality of source rocks in the offshore northern Perth Basin. Kinetic data that can be used as input parameters for modelling hydrocarbon generation are also provided for Hovea Member and Irwin River Coals Measures source rocks.

Water depth - a critical factor for exhalative ore deposits

If it can be ascertained from sedimentological, palaeontological and/or fluid inclusion evidence that sea water at the site of exhalation was shallow (&lt;500 m) or deep (&gt;1000 m), then predictions can be made on the style of mineralisation expected in the facies present. Shallow-water deposits most commonly contain stratiform Fe-Mn, Ba, Zn-Pb (usually pyritic) ore underlain by, or associated with, a footwall alteration zone of vein, disseminated, or stockwork ore (Cu Â± Au, Sn, quartz, tourmaline, carbonate, fluorite). In deep-water settings, stratiform Fe-Mn-Ba, Cu-Zn-Pb (commonly pyrrhotite-bearing), Sn and W ore is not usually underlain by a footwall alteration pipe, and the stratiform ore contains quartz, tourmaline, carbonate or fluorite. In shallow-water deposits, boiling, fluid mixing, or other mechanisms could cause a temperature decrease and resultant mineral precipitation beneath the sea water/rock interface. In deep water, fluid mixing with resultant temperature decrease takes place primarily in sea water and not beneath the sea water/rock interface.
