Honeysuckle Creek 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 Honeysuckle Creek doserate grid geodetic has a cell size of 0.00021 degrees (approximately 21m) and shows the terrestrial dose rate of the SMMSP - MagSpec - Honeysuckle Creek, Vic, 2001. The data used to produce this grid was acquired in 2001 by the VIC Government, and consisted of 14795 line-kilometres of data at 100m line spacing and 60m terrain clearance.

Geochronology of metasedimentary and granitic rocks in the Tanami Province: 1880–1790 Ma geodynamic setting of the North Australian Craton

Dating of detrital zircons from the Paleoproterozoic Tanami Group shows that Archean detritus dominates the lower part of the succession, and c. 1865 Ma detritus with a minor c. 2500 Ma component dominates the upper part. Detrital zircon ages for the upper Stubbins Formation in Western Australia are consistent with a correlation with the upper Dead Bullock Formation in the Northern Territory, whereas previously collected data for the Mount Charles Formation are consistent with a correlation with the lower Dead Bullock Formation. Metasedimentary rocks with a dominant c. 1865 Ma detrital zircon age component were deposited over much of the North Australian Craton between c. 1865 and 1840 Ma, possibly within a back-arc setting related to a plate margin north of the currently preserved craton. Tectonism at c. 1865 Ma in the northeastern part of the craton may represent remnants of a larger orogen that acted as the dominant source of sediment. The widespread occurrence of metasedimentary rocks with this distinctive provenance signature suggests craton assembly was largely complete prior to deposition. Dates of 1807–1800 Ma for granitic rocks in the western part of the orogen confirm that they were emplaced during the 1810–1790 Ma Stafford Event. These granitic rocks form part of an &gt;800 km-long west-northwesterly trending magmatic belt, the development of which was coeval with bimodal magmatism, extension and sedimentation in other parts of the craton. This magmatism may have been a consequence of intraplate extension, possibly driven by processes along the southern craton margin. Folding and orogenic Au mineralization in the Granites–Tanami Orogen during the Stafford Event may reflect transient compression punctuating a more prolonged period of extension.

Geochemical characteristics of oil and gas accumulations used to define the petroleum systems of the Browse Basin.

The Browse Basin lies offshore from Western Australia's Kimberley region and hosts vast accumulations of natural gas, some of which are rich in condensate, making it Australia's next major liquefied natural gas (LNG) producing province on the North West Shelf. This presentation discusses the four Mesozoic petroleum systems that are currently defined in the Browse Basin. There is a dry-gas-prone petroleum system, presumably sourced from the LowerMiddle Jurassic Plover Formation, which is pervasive across the entire basin. Three other petroleum systems are presently only recognised within the Caswell Sub-basin, being sourced by more liquid-prone source rocks within Jurassic and Lower Cretaceous sedimentary rocks. These petroleum systems are summarised as follows;
    EarlyMiddle Jurassic Petroleum System (Westralian 1, or W1); represented by accumulations on the BrecknockScott Reef Trend, mostly reservoired within the Plover Formation.
    Jurassic Petroleum System (Westralian 1 to 2, or W1W2); represented by the Crux gas accumulation, reservoired in Nome, Plover and Vulcan formations.
    Late Jurassicearliest Cretaceous Petroleum System (Westralian 2 and 3, or W2+W3); probably represented by the Ichthys (Brewster) accumulation reservoired in the Brewster Member of the upper Vulcan Formation.
    Early Cretaceous Petroleum System (Westralian 3, or W3); represented by the Cornea and Gwydion oil accumulations, and the Caswell 2 oil accumulation reservoired within either the Heywood or Jamieson formations. However, gas in the greater Cornea structure is typically biodegraded and may originate from the Plover Formation (W1) as determined by geochemical evidence from the carbon isotopic signature of neo-pentane.
Further work is in progress to confirm these petroleum systems and redefine their extent by correlating the wet gases and oils with their source rocks.

The occurrence of Thylacinus in Tertiary Rocks from Papua New Guinea

Collecting at the Pliocene Awe fauna type locality (Plane 1967) on the west bank of the Watut River, in the Morobe District of Papua New Guinea during 1962 and 1963 produced a number of fine mandibles and maxillae of Protemnodon otibandus. Although these were the highlights of the collecting in this quarry the bulk of the collection were isolated teeth of P. otibandus, Kolopsoides cultridens and lesser number of Kolopsis rotundus. Among the collection a half tooth passed unnoticed during the sorting and subsequent study of the fauna. This tooth has now, thanks to L. Marshall of the Department of Palaeontology, University of California, Berkley, been brought to my attention. It is the posterior half of a Thylacinus lower second premolar. The specimen documents the earliest record of this genus beyond the mainland of Australia.

Joint NTGS-AGSO age determination program 1999-2001

This Record is a source document listing new zircon U-Pb isotopic ages measured for key rocks units in Australia's Northern
Territory. The samples are critical reference points in the conduct of, and interpretations made by, the Regional Geoscience
Program of the Northern Territory Geological Survey (NTGS) and the dating was conducted within the Geochronology group
of AGSO-Geoscience Australia. The relationships between these ages, their regional significance, and the event chronologies
they constrain will be discussed in other NTGS outlets and is not developed here. The source listing of ages is being made
available early as a reference document, with brief details of the locations and geological context of each sample and comments
on each age interpretation, as a service to all geoscientists and mineral explorers with interests in the geology of the Northern
Territory. The analytical data are plotted on Concordia diagrams (see Figures) and are summarised in Appendix Tables A1-
A43. These tables are not reproduced here, but are available from NTGS upon request.

AUSGeoid98 v.1.0 data files:  (sc53-12)

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.

Gravity and Granites: Technical notes on mapping relationship between known granites and gravity

Gravity anomalies over granite bodies are often negative polarity and rounded polygons. These characteristics were used to trial a method to map possible locations of subsurface granite bodies.
Two approaches were used to outline the geometry of rounded gravity anomalies:
a) Contouring of the residual Bouguer gravity field after removal of a regional field computed by filtering of the gravity field.
b) Detection of edges defined by maximum horizontal gradient of the residual Bouguer gravity field.
The resulting polygons are coloured according to whether granite outcrop, or encounter in wells, falls within the gravity polygon, is near such outcrop, or not proximal to outcrop.
The processing was done using software developed by the author in the Perl programming language and stored in the Energy Division software repository. The processing was organised to run in batch mode on any system on which Perl is installed, MS-Windows, Unix, Linux or NCI systems.
The input and output data files are ERMapper ASCII vector format and exported to ArcGIS shape files. The visualisation tool was ER-Mapper.

Horsham-Hamilton, VIC, 1974 (GSV0118) (P414), 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 Horsham-Hamilton, VIC, 1974 (GSV0118) survey were acquired in 1974 by the VIC Government, and consisted of 3047 line-kilometres of data at 10000m line spacing and 460m 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.
