Newmont Detailed Gravity Survey - Central Arunta, NT, 2006 (P200681), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Newmont Detailed Gravity Survey - Central Arunta, NT, 2006 (P200681) contains a total of 203 point data values acquired at a spacing of 2000 metres. The data is located in NT and were acquired in 2006, under project No. 200681 for Newmont Exploration Pty Ltd.

Upper Cretaceous ammonites from the Carnarvon Basin of Western Australia. 1, The Heteromorph Lytoceratina

This Bulletin is the first part of a monograph on the Upper Cretaceous Ammonoidea of the Carnarvon Basin, and deals with the Heteromorph Lytoceratina of Santon-Campanian and Maastrichtian age. It is proposed to subdivide the Heteromorph Lytoceratina further by removing a number of genera from Turrilitaceae to form a new superfamily Diplomocerataceae. It is shown that Diplomocerataceae are derived from Cicatritidae, whereas Turrilitaceae stem from Macroscaphitidae. Diplomocerataceae are represented in Western Australia by the genera Hyphantoceras Hyatt, Diplomoceras Spath, Bostrychoceras Hyatt, and Eudiplomoceras nov.; Turrilitaceae by Baculites Lamarck, Eubaculites Spath, Giralites nov., Eubaculiceras nov., Cardabites nov., Nostoceras Hyatt, Glyptoxoceras Spath, and Neohamites novo Scaphitaceae are represented by a single specimen of a new species of lndoscaphites Spath. Thirty species of the above 13 genera are described, 17 of which are new.

Northwest Mulgathing Complex - Interpreted PreCambrian Basement Geology map 1:250 000 scale

An interpretation of the Mulgathing Complex, a late Archaean high grade metamorphic complex in the northwest of the Gawler Craton, host to the Challenger Au deposit. This interpretation is based on gravity, drillhole and airborne magnetic datasets, ground reconnaissance and published geological maps.
This map presents an interpretation of basement geology based on ground reconnaissance,interrogation of drill-hole databases, and interpretation of airborne magnetics, gravity data, and previous geological mapping: Benbow, M.C., 1981, COOBER PEDY 1:250 000 Geological Series SH53-6; Daly, S.J., 1985, TARCOOLA 1:250 000 Geological Series SH53-10; Benbow, M.C., 1986, TALLARINGA 1:250 000 Geological Series SH53-5; Benbow, M.C. et al., 1995, BARTON 1:250 000 Geological Series SH53-9; Vitols, V., 1974, COOBER PEDY 1:250 000 Geological Series SH53-6(Preliminary Edition). All the above authors from the Office of Minerals and Energy Resources, South Australia (or predecessors).
The boundaries of some mapped units were modified to be consistent with geophysical data or ground truthing. As the map area is essentially under cover, the interpretation is necessarily broad and many anomalies remain uninterpreted. Granulite facies metamorphism has demagnetised much of the Mulgathing Complex and lithological packages, known to exist, could not be distinguished or differentiated. Areas where Palaeozoic cover has attenuated potential fields are shown.
Gravity data come from 3851 stations out of a combined database of the Gawler Craton compiled by N.G. Direen (AGSO, unpublished data). These data comprise Commonwealth, State, and open file company surveys. Gravity data were converted to Simple Bouguer Anomalies at an S.G. of 2.67, according to the method of Wellman et al. (1985, BMR Record 261). Geodetic data were converted onto WGS84 and projected to MGA53. An ERMapper grid was produced in Intrepid using a multi-pass, variable density minimum curvature technique with a final grid cell size of 200 m. Intermediate gridding parameters included a coarse cell size of 21 km and a 32 cell extrapolation radius.

GSQ Westmoreland ppm 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 90m) and shows uranium element concentration of the Westmoreland, Qld, 2007 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2006 by the QLD Government, and consisted of 60570 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Quantifying social vulnerability: a methodology for identifying those at risk to natural hazards

Australia is exposed to a wide range of natural hazards, including earthquake, cyclone,
landslide, flood, storm surge, severe wind, bushfire, coastal erosion, hail storm and
drought. How each person will fare in the event of a natural hazard is influenced not just
by exposure to infrastructure, but also by personal attributes, community support, access
to resources and governmental management. This network of factors affecting
social vulnerability to natural hazards, combined with the complex linkages found in
cities and the behaviour of the hazard itself, all contribute to the development of a risk
assessment.

Kalgoorlie seismic profiling 1997 : operations, processing, and interpretation report

The Australian Geological Survey Organisation (AGSO) through the partnership in the Australian  Geodynamics Cooperative Research Centre (AGCRC) and Kalgoorlie Consolidated Gold Mines (KCGM) completed a joint research project to image the crustal structure of the Kalgoorlie region to develop a knowledge of the shallow and deep structures, tectonics, and fluid migration pathways. The Australian  National Seismic Imaging Resource (ANSIR) was contracted to acquire the seismic data. The project's  objectives were to obtain a better understanding of
- sub-surface geology at a regional and mine scale
- provide more information on regional crustal thickness and major features 
- stratigraphic and structural architecture of the mineral system 
- timing and locations of fluid migration pathways  
The seismic survey obtained 25 km of 10 fold CMP (common midpoint) regional reflection seismic data  along two traverses and 8 km of 10 fold CMP high-resolution reflection seismic data along another two  traverses. The data are of good quality and similar to both the 1991 and 1999 Eastern Goldfields reflection  seismic data to the north and south of the survey area. 
The major outcome of imaging the four localities included mapping the Golden Mile and Bolder-Lefroy Faults, and the Boorara Shear at depth. This new information indicates the Golden Mile Mine was fed by a suite of relatively minor faults dangling off the major crustal-scale Boorara Shear. The dangling element relates to percolation theory. The detachment surface was imaged on all seismic traverses. Thrust duplexes were interpreted above the detachment surface.

AUSGeoid98 v.1.0 data files:  (si49-05)

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.

Pythonine snakes (Boidae) from the Miocene of Australia

Two new species of pythonine snake (Boidae) are described from middle to late Miocene local faunas at Riversleigh (Queensland) and Bullock Creek (Northern Territory). To date, they are the oldest records of snakes in Australia, and their age implies that snakes entered Australia in the late Cretaceous or early Tertiary, before the break up of Gondwanaland.

Benthic Nutrient Fluxes in Wallis Lake, NSW - February 2003

Geoscience Australia conducted a survey to measure the benthic nutrient fluxes in Wallis Lake, during February 2003. The objectives were to:
1.  measure the nutrient (and other metabolite) fluxes across the sediment-water interface at sites in Pipers Creek, Muddy Creek, Wallis Creek and in the Central Basin of Wallis Lake;
2.  describe key processes controlling the nutrient fluxes across the sediment-water interface at each of the four sites; and
3.  determine the trophic state and assess the estuarine condition of the four selected sites in Wallis Lake.
The results of this recent summertime survey were compared to the observations made during the winter survey conducted in June, 2000.
Pipers Creek and muddy Creek were similar in that they were both poorly flushed and close to nutrient discharges.  These sites are at risk of experiencing eutrophic conditions.  Wallis Creek had a high carbon loading, however the presence of seagrass and high denitrification efficiencies means this site remains in a 'good condition.  Similarly, the Central Basin remains in a 'good' condition despite an increase in the carbon loading between winter and summer.

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - TMI RTP image (PGrav)

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 2019 Total magnetic Intensity (TMI) grid of Australia has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the sixth edition was released in 2015, data from 234 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. The 2019 national grid was derived from a re-levelling of the national magnetic grid database. The survey grids were levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS), which serves as a baseline to constrain long wavelengths in the final grid. It is estimated that 33 500 000 line-kilometres of survey data were acquired to produce the 2019 grid data, about 2 000 000 line-kilometres more than for the previous edition. 
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. .
 This Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - TMI RTP image (PGrav) is a pseudocolour image of the TMI grid of the Magnetic Anomaly Map of Australia, Seventh Edition, 2019.
This grid has a cell size of 0.00083 degrees (approximately 88m). This pseudocolour image shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The image can also be used to locate structural features such as dykes.
