Bendigo elevation grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Bendigo elevation grid geodetic is elevation data for the Bendigo, Vic, 1994 (GSV2688). This survey was acquired under the project No. 606 for the geological survey of VIC. The grid has a cell size of 0.00083 degrees (approximately 84m).  This grid contains the ground elevation relative to the geoid for the Bendigo, Vic, 1994 (GSV2688). It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Geophysical interpretation of Proterozoic mafic-ultramafic intrusions in the Arunta Region, central Australia

The purpose of this study was to follow on from previous work by Hoatson &amp; Stewart (2001), who summarised the field relationships and mineralisation features of 16 Proterozoic mafic -ultramafic intrusions in the Arunta Region of central Australia. The major aims of this study were to investigate various geophysical datasets in order to define the total sub-cropping extent of the outcropping intrusions, as well as to identify other previously unknown mafic-ultramafic intrusions concealed beneath alluvial cover.
Various data enhancements and imaging processes were applied to grids of the magnetic, gravity and gamma-ray spectrometric data, while 2-D computer modelling was carried out on the magnetic data. From these manipulations of the data it was possible to define various features of the outcropping intrusions. These feautures included: total sub-cropping extent; depth of burial beneath alluvial cover; internal structure; spatial association with faults and; the orientation of the intrusions.
The larger outcropping intrusions exhibited a high gravity response, but the internal structure of the intrusions could not be determined due to the sparse gravity station spacing. However, the magnetic response of the the intrusions were variable and were more sensitive to the composition, metamorphic grade and post emplacement deformation. Generally the lower the metamorphic grade, the easier it was to determine magnetic signatures originating from primary igneous features such as macroscopic layering and contrasting rock compositions. The high-grade, intensely deformed intrusions exhibit more complex magnetic signatures and are less readily differentiated from country rock. The majority of the 14 outcropping intrusions investigated have sub-cropping extents far exceeding the outcropping component. The depth of burial for the sub-cropping intrusions was less than 120m.
A number of previously unknown concealed mafic-ultramfic intrusions were identified based on their gravity and magnetic signatures. A series of bodies were identified on a prominent east-west trending gravity ridge on which the Andrew Yound Hills mafic intrusion outcrops. These bodies have similar magnetic character to the Andrew Yound Hills intrusion and are probably related. A series of ovoid shaped magnetic highs, located east of the Mount Hay Granulite, were also identified as possible plug-like mafic intrusions.
The study highlighted the defeciency of the existing gravity data, which consists mostly of 11 km station spacing. This sparsity of gravity data does not allow the determination of internal composition based on density variations for the larger bodies, while smaller bodies are generally not imaged.

Geology of the MacDonald

These data are a digital representation of information depicted on the printed map of the MacDonald 1:250 000 Geological Series produced by AGSO and the Geological Survey of Western Australia (GSWA) in 1968.
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

Australian Mineral Exploration - A Review of Exploration for the Year 2005: Extended edition

Australian mineral exploration spending in 2004-05 rose by 31% to $1028.3 million of which 39.3% was spent on the search for new deposits. 
Total global non-ferrous mineral exploration budgets rose 38% to an estimated US$5.1 billion in 2005. 
Western Australia received 59% of Australian mineral exploration spending in 2004-05 as spending rose in all States except Victoria. 
Gold remained the main target but its share of spending was eroded by increased spending on nickel, copper, iron ore, coal and uranium. 
Exploration resulted in significant increases in resources at known deposits and a substantial number of drill intersections of economic interest, the most notable being the discoveries of copper-gold mineralisation at Carrapateena (Gawler Craton), mineral sand in the Eucla Basin, and gold at the Trident deposit (Yilgarn Craton).

Lost in Space? Setting a new direction for Australia's space science and industry sector

Australia had a long and illustrious association with 'space science'. The first Australians used the patterns of the stars to guide them to seasonal food sources. Captain Cook arrived here on the way home from a voyage to chart the transit of Venus, with the goal of improving navigational technology. When Governor Phillip founded the first European settlement, he brought with him the astronomer William Dawes. Australia was the fourth nation to build and launch a satellite from its own territory. The 'big dish' at Parkes played an important role in the Apollo missions and the discovery of the first quasar.

Ground surface movement in the northern Surat Basin derived from campaign GPS measurements

This Geoscience Australia Record summarises the collection, analysis and results of three Global Positioning System (GPS) campaign surveys conducted in 2015, 2016 and 2019 in the northern Surat Basin, Queensland, Australia. During each campaign, we collected at least seven continuous days of GPS observations at each of the 65 sites of a geodetic network established by Geoscience Australia in 2014. Our analysis of the collected GPS data reveals statistically significant downward vertical ground surface movement between 2015 and 2016, 2015 and 2019, or both, at 18 of the 65 geodetic sites. Two of the 18 sites have recorded downward vertical ground surface movement of more than 100 millimetres: SB36 near Miles (125 mm) and SB49 near Wandoan (218 mm). Further work is required to help better resolve the temporal and spatial pattern of ground surface movement in the northern Surat Basin. This could include further GPS campaign surveys, analysis of GPS data from continuously operating reference sites in south-east Queensland, and a detailed comparison of surface deformation observed with GPS and interferometric synthetic aperture radar (InSAR) data; extending on the work described in McCubbine et al. (2022).

This resource contains multibeam bathymetry data collected as part of the Darwin and Bynoe Harbour Habitat Mapping Project undertaken by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources). The data were acquired during the period from 3 to 27 May 2016 on the RV Solander (survey SOL6432/GA04452). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) project is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions.
The specific objectives of the survey were to:


Obtain high-resolution geophysical (multibeam bathymetry) data for Bynoe Harbour;


Characterise seabed substrates (multibeam acoustic backscatter properties, seabed sediment grainsize, sediment chemistry) for Bynoe Harbour; and


Collect tidal data for the survey area. 
Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, seabed still images and video footage of grab sample locations, and oceanographic information including tidal data and water column sound velocity profiles.


This V1 dataset contains two 2m resolution 32-bit geotiff of the SOL6432 survey area produced from the processed Kongsberg EM2040C bathymetry data.

Application of aeromagnetic surveys to sedimentary basin studies

While aeromagnetic surveys have been mainly used in the past for mapping depth to magnetic basement of sedimentary basins and for delineating igneous units within the sedimentary section, the advent of high-resolution surveys flown close to the ground with close line spacing has revealed the existence of significant magnetic anomalies arising from sedimentary layers and their structure.  As a result of these developments, aeromagnetic surveys now have greater relevance to sedimentary basin studies.  The aim of this paper is to explain the types of aeromagnetic responses that arise from the various geological features associated with sedimentary basins and how these responses can be interpreted in the context of basin studies.  The discussion is directed to petroleum exploration, but features relevant to mineral exploration are mentioned and, in any case, the generalities presented apply to virtually any study of sedimentary basins.

Mt Anderson - McClarty Hills, WA, 2009 (North Canning 3) (P1212), 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 Mt Anderson - McClarty Hills, WA, 2009 (North Canning 3) survey were acquired in 2009 by the WA Government, and consisted of 99192 line-kilometres of data at 400m line spacing and 60m 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.
