Noonkanbah 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

NE Queensland (Charters Towers, Bowen, Proserpine), QLD, 1982-84 (P482), 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 NE Queensland (Charters Towers, Bowen, Proserpine), QLD, 1982-84 survey were acquired in 1982 by the QLD Government, and consisted of 34769 line-kilometres of data at 1500m line spacing and 150m 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.

1996 Vulcan Sub-basin Airborne Laser Fluorosensor Survey Interpretation Report : (WGC Vulcan Graben Survey number 1113)

The Vulcan Graben airborne laser fluorosensor (ALF) survey is located in the Vulcan Sub-basin, Timor Sea. The survey was flown on December 2nd 1996. 149 lines were acquired at 300 m spacing in a NW-SE orientation. A total of 1,569,074 spectra were collected at an average spacing of 1.45 m to 1.65 m.Of the 183 fluors picked during the refined interpretation, 70 were large fluors with a F/R ratio larger then 0.3. Some of the fluor clusters may be related to leakage from the Skua Field and Spruce Prospect although direct correlation between fluor clusters and accumulations are not reliable. The fluorescence peak wavelength tends to move to longer values moving from the NE to the SW.

AUSGeoid98 v.1.0 data files:  (sk53-05)

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.

Reinterpretation of Isotopic Ages from The Halls Creek Mobile Zone, Northwestern Australia

Data presented elsewhere in this issue (Page, Blake, and Mahon, 1976) provide some of the first ages from The Granites-Tanami Block. Unfortunately it did not prove possible to date or even adequately sample the weathered low grade metasediments and metavolcanics of the Tanami complex, clearly the oldest exposed component of the block. For this reason age data pertaining to the Halls Creek Group, the suggested correlative of the Tanami complex in the Kimberley region to the northwest (Page et al., this volume, Fig. 1), are now reinterpreted in an attempt to arrive at a reasonable estimate of the age of these old rocks. In considering the available information on the geochronology of this part of Australia it is also pertinent to review the age of the Whitewater Volcanics, Castlereagh Hill Porphyry and Bow River Granite, which form a Lower Proterozoic comagmatic suite overlying and intruding the Halls Creek Group in the Halls Creek Mobile Zone.

Seabed morphology and geomorphology of Zeehan Marine Park, south-eastern Australia - Version 1

This data product contains seabed morphology and geomorphology information for a subset area of Zeehan Marine Park. A nationally consistent seabed geomorphology classification scheme was used to map and classify the distribution of key seabed features. The Zeehan Marine Park seabed morphology and geomorphology maps were derived from a 2 m horizontal resolution bathymetry DEM compiled from a multibeam survey undertaken for Parks Australia by the University of Tasmania.
Semi-automated GIS mapping tools (GA-SaMMT); (Huang et. al., 2022; eCat Record 146832) were applied to a bathymetry digital elevation model (DEM) in a GIS environment (ESRI ArcGIS Pro) to map polygon extents (topographic high, low, and planar) and to quantitatively characterise polygon geometries. Geometric attributes were then used to classify each shape into discrete Morphology Feature types (Dove et. al., 2020; eCat Record 144305). Seabed geomorphology features were interpreted by applying additional datasets and domain knowledge to inform their geomorphic characterisation (Nanson et. al., 2023; eCat Record 147818). Where available, backscatter intensity, seabed imagery, and survey reports supplemented the bathymetry DEM and morphology classifications to inform the geomorphic interpretations.
The data product and classification schema are fully described in the accompanying Data Product Specification.

Thermomechanical models of the Australian plate

Output Type: Exploring for the Future Extended Abstract

Short Abstract: The thickness and thermal structure of continental lithosphere influences the location of seismic and volcanic hazards and is important for predicting long-term evolution of landscapes, sedimentary basins, and the distribution of natural resources. In this project, we have developed new, continental-scale models of the thermomechanical structure of the Australian plate. We begin by compiling an inventory of >15,000 geochemical analyses of peridotitic xenoliths and xenocrysts from across the continent that have been carried up to the surface in volcanic eruptions. We apply thermobarometric techniques to constrain their pressure and temperature of equilibration and perform steady-state heat flow modelling to assess the paleogeotherm beneath these sites. We subsequently use the paleogeotherms as constraints in a Bayesian calibration of anelasticity at seismic frequencies to provide a mapping between seismic velocity and temperature as a function of pressure. We apply this method to several regional-scale seismic tomography models, allowing the temperature to be continuously mapped throughout the Australian lithospheric and asthenospheric mantle. Our models include assessment of uncertainties and can be used to query thermomechanical properties, such as lithospheric thickness, heat flow through the Moho, and the Curie depth.
