Napier Downs Gravity (P196239), 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 Napier Downs Gravity (P196239) contains a total of 369 point data values acquired at a spacing between 804 and 2140 metres. The data is located in WA and were acquired in 1962, under project No. 196239 for Alliance Oil Development NL.

Australia's Identified Mineral Resources 1997

In 1996, Australia's Economic Demonstrated Resources (EDR) of cobalt, gold, nickel, phosphate rock and tantalum increased substantially, while EDR of bauxite, lead, lithium, platinum group metals (PGM), silver and zinc rose slightly. There was a significant reduction in EDR of gem and near gem diamond and industrial diamond due to ongoing high levels of production. Magnesite and tin EDR were also significantly reduced as a result of depletion due to production and reassessment of deposits. EDR of all other commodities remained unchanged or had minor reductions.
Australia continues to rank highly as one of the world's leading mineral resource nations. It has the world's largest EDR of bauxite, lead, mineral sands (ilmenite, rutile and zircon), silver, tantalum, uranium and zinc. In addition, its EDR is in the top six worldwide for black coal, brown coal, cobalt, copper, gold, iron ore, lithium, manganese ore, nickel, rare earth oxides, gem and near gem diamond and industrial diamond.
Mineral exploration expenditure rose by 7.5% in 1995-96 to $960.2 million from $893.3 million in the previous year. Increases were recorded in all states and the Northern Territory. Gold was again the main target, accounting for 57% of the total expenditure.
In 1995-96 mineral resources exports increased to a new record of $34.7 billion (thousand million), a rise of 12.7% over the previous fiscal year. These export earnings comprised 60% of Australia's commodity exports, 45% of merchandise exports and 35% of the country's total exports of goods and services. The Australian Bureau of Agricultural and Resource Economics (ABARE) forecast export earnings to set a further record in 1996-97, rising by nearly 4% to over $36 billion.

Seafloor environments of the eastern Timor Sea, Northern Australia: Extractable elements in seabed sediments.

The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises concentrations of Fe, Mn, Co, Cu, Zn, Ge, As, Cd and Pb in seabed sediments (0-2 cm) that were extracted in cold, dilute HCl.

The earthquake near Nhill, western Victoria, on 22 December 1987 and the seismicity of eastern Australia

On 22 December 1987 a shallow magnitude 4.9 earthquake occurred in western Victoria where there is no record of previous seismic activity. It was felt over a remarkably wide area of Victoria and South Australia and caused minor damage in the epicentral area.  There were no foreshocks and only ten aftershocks were recorded on the nearest seismograph, near Willalooka in South Australia.  All ten occurred within five days of the mainshock. The earthquake occurred in a seismic zone that  extends over a 500 km wide belt along the entire eastern coast of Australia linking the Southeast Seismic Zone of South Australia with the Eastern Highlands Zone through Queensland, New South Wales, Victoria and Tasmania.  Its focal mechanism, a thrust with a principal stress directed east-west, is typical of earthquakes in the Lachlan Fold Belt.

Summary of results. 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.

Tennant Creek 2D Crustal Reflection Seismic Survey, NT 2015

The Tennant Creek crustal reflection seismic survey was co-funded by the Northern Territory Government through the Creating Opportunities for Resource Exploration (CORE) initiative and Emmerson Resources Limited. HiSeis Pty Ltd acquired the 60 km 2D seismic line (Line 101) proximal to the Tennant Creek town site and mining facilities, from 14 June to the 21 June 2015. Geoscience Australia, as part of the Exploring for the Future funding, provided specialised hard-rock seismic data processing to image deep crustal structures and sedimentary layers at the near surface. The objective of the 2D survey was to define the regional scale structures contributing to the mineralisation in the area and target previously unidentified areas of prospectivity in the Tennant Creek Mineral Field, as well as demonstrate the value of seismic reflection for the minerals industry and to the geoscience community.

Methodologies for multibeam seabed hardness mapping in the Timor Sea - Topographic Position Index

This dataset contains topographic position index data from seabed mapping surveys on the Van Diemen Rise in the eastern Joseph Bonaparte Gulf of the Timor Sea. The survey was conducted under a Memorandum of Understanding between Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) in two consecutive years 2009 (GA survey number GA-0322 and AIMS survey number SOL4934) and 2010 (GA survey number GA-0325 and AIMS survey number SOL5117). The surveys obtained detailed geological (sedimentological, geochemical, geophysical) and biological data (macro-benthic and infaunal diversity, community structure) for the banks, channels and plains to investigate relationships between the physical environment and associated biota for biodiversity prediction. The surveys also provide Arafura-Timor Sea, and wider northern Australian marine region context for the benthic biodiversity of the Van Diemen Rise. Four study areas were investigated across the outer to inner shelf. Refer to the GA record 'Methodologies for seabed substrate characterisation using multibeam bathymetry, backscatter, and video data: A case study for the Eastern Joseph Bonaparte Gulf, Northern Australia' for further information on processing techniques applied (GeoCat: 74092; GA Record: 2013/11).
