Summary of results. Joint NTGS-GA geochronology project : Rum Jungle, basement to southern Georgina Basin and eastern Arunta Region 2001-2003

This record presents new SHRIMP U-Pb zircon geochronology results from the Rum Jungle area of the Pine Creek Orogen, the northeastern margin of the Arunta Region and basement underlying the southern Georgina Basin. The samples were collected as part of geoscientific studies of these regions by the Northern Territory Geological Survey in 2001–2002, and the data were obtained and interpreted through the NTGS-Geoscience Australia (GA) geochronology project in the period 2001–2003.
Six samples of intrusive rocks from the Rum Jungle Complex all give SHRIMP U-Pb zircon ages in the range 2545 ± 4 Ma to 2521 ± 4 Ma, suggesting that the entire complex comprises Neoarchaean rocks. Some of these rocks show evidence for new zircon growth and/or recrystallisation during a poorly defined event, probably in the early Palaeoproterozoic. A sample of Beestons Formation, the basal unit of the Pine Creek Orogen immediately overlying the Rum Jungle Complex, has a predominantly Neoarchaean provenance and a maximum deposition age of 2506 ± 14 Ma. A sample of Acacia Gap Quartzite Member of the Wildman Siltstone (Mount Partridge Group) also has a Neoarchaean provenance and a maximum deposition age of 2512 ± 13 Ma. 
Three samples were dated from crystalline basement intersected in drillcore beneath the southern Georgina Basin in TOBERMOREY1. A sample of granitic rock from drillhole NTGS99/1 has an age of 1846 ± 6 Ma. Granites intersected at the base of drillholes Hacking-1 and Owen-2 have ages of 1749 ± 7 Ma and 1763 ± 5 Ma, respectively. These are consistent with the ages of three granite samples from outcrop in TOBERMOREY, which have ages ranging from 1766 ± 7 Ma to 1753 ± 7 Ma. In one of these samples, two zircons have early Mesozoic ages, reflecting an event of
unknown significance.

National Geochemical Survey of Australia: Plutonium Isotopes Dataset

Preamble -- The 'National Geochemical Survey of Australia: The Geochemical Atlas of Australia' was published in July 2011 along with a digital copy of the NGSA geochemical dataset (doi: 10.11636/Record.2011.020). The NGSA project is described here: www.ga.gov.au/ngsa. The present dataset contains additional geochemical data obtained on NGSA samples: the Plutonium Isotopes Dataset.
Abstract -- Seventy three fine-fraction (&lt;75 um) Top Outlet Sediment (TOS, 0 – 10 cm depth) NGSA samples from Queensland were analysed for the plutonium (Pu) isotopes 238Pu and 239+240Pu (unresolved 239Pu and 240Pu) to determine: (1) if Pu is detectable in the Australian environment; and (2) what the levels and ranges of Pu retention in selected Queensland catchment soils are. 
Radiochemical analyses were performed by alpha spectrometry at the radioanalytical laboratories of Radiation and Nuclear Sciences, Department of Health, Queensland, and at the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), Victoria. The method yielded a 239+240Pu trace-level detection limit of 0.04 mBq/g (equivalent to 10.4 fg/kg or 0.0056 net counts per minute) with a relative standard deviation (RSD) of 15.1%. The average tracer recovery was 69% (RSD 25%) over a 3-day count. Total analytical uncertainty ranged from 19% to 90% at close to detection limits. Field duplicate repeatability for 239+240Pu activity concentration ranged from 18% to 45%, which in part at least reflects the inherent heterogeneity of soil/sediments containing refractory particles exhibiting variation in Pu activity concentrations. Analytical duplicate repeatability for 239+240Pu activity concentration ranged from 10% to 23%, with the mean activity concentration and error of the replicates reported with propagation of errors. 
The results show a wide range of 239+240Pu activity concentration in the fine TOS NGSA samples across Queensland (N = 73):
239+240Pu: Min = &lt;0.04 mBq/g; Med ± MAD (median absolute deviation) = 0.09 ± 0.07 mBq/g; Mean ± SD = 0.29 ± 0.72 mBq/g; 95th percentile = 1.53 mBq/g; Max = 4.88 mBq/g. In comparison the world average background is estimated at 0.2 mBq/g. Analytical results for 39% of samples were below detection. 
Six samples with 239+240Pu &gt; 0.18 mBq/g (70th percentile) were also analysed for 238Pu by the same alpha spectrometry method. Results ranged from 0.04 to 0.1 mBq/g (N = 6).
The complete dataset is available to download as a comma separated values (CSV) file from Geoscience Australia's website (https://pid.geoscience.gov.au/dataset/ga/144101).

Australia and the Melanesian arcs: a review of tectonic settings

Until about 1950, the southwest Pacific region was thought by many to be the foundered eastern half of Greater Australia, Tasmantis.  The Outer Melanesian arcs defined the northern part of the Tasmantis boundary to the Pacific Ocean basin.  Others considered the Inner Melanesian arcs to be the expanded rim of the Australian craton, the outwardly propagated expression of the Tasman Geosyncline.  With the surge of exploration after World War II, new data showed that the outer islands could not be matched with island-arc models such as the Sunda Arc, and that New Caledonia, of the inner arcs, seemed increasingly to have Tasman Geosyncline affinities.  By 1968, the land and sea data had produced a cluttered and confused picture, ripe for the application of new global tectonic models.  After 1968, the Tasman Sea was shown to be a product of Late Cretaceous seafloor spreading and New Caledonia was accepted as part of the expanded rim of eastern Gondwana.  The sea floor between the inner and outer chains was relatively young and the product of complex seafloor spreading.  Over recent years, the southwest Pacific has in many respects been a showcase of plate tectonic theory.  The region is intensely mobile.  The obliquely convergent northern Indo-AustralianlPacific plate boundary carries great crustal blocks as allochthons to join others in eastern Indonesia.  These crustal blocks also undergo vertical and rotational movement.  The outer island chains do not fit the conventional models of an island arc - they are hybrid entities made up of the byproducts of subduction and of exotic terranes; as arcs, they continually change composition, form and configuration, even as they are being built.  These outer chains are components of what is here called an accommodation boundary .

GSNSW Exploration NSW Area M Kayrunnera magnetic rtp grid geodetic

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.
This magnetic grid has a cell size of 0.00048 degrees (approximately 50m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 1999 by the NSW Government, and consisted of 55448 line-kilometres of data at 250m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

GSWA Paterson South East doserate 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 GSWA Paterson South East doserate grid geodetic has a cell size of 0.00083 degrees (approximately 89m) and shows the terrestrial dose rate of the Paterson Southeast, WA, 2005. The data used to produce this grid was acquired in 2005 by the WA Government, and consisted of 28455 line-kilometres of data at 400m line spacing and 60m terrain clearance.

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.
