GSWA Ravensthorpe percent Potassium 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.
This radiometric potassium grid has a cell size of 0.00083 degrees (approximately 85m) and shows potassium element concentration of the Southern Yilgarn (Newdegate, Ravensthorpe, Bremer Bay), WA, 2004 in units of percent (or %). The data used to produce this grid was acquired in 2004 by the WA Government, and consisted of 99719 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Australia's Maritime Zones/Boundaries Map

This edition has been superseded by the Australia's Maritime Zones Edition 4 map published in October 2013.  Geocat 69822.
It no longer correctly reflects Australia's maritime zones and is kept for historical record only.
This map has been derived from Geoscience Australia's Australian Maritime Boundaries (AMB) version 2.0 data which is a digital representation of Australia's territorial sea baseline and the maritime limits and boundaries as established under the Sea and Submerged Lands Act 1973. 
The map describes the different maritime zones, explains how Australia defines and updates its maritime boundaries, and lists the different maritime boundary arrangements with Indonesia, Papua New Guinea, Solomon Islands, France (New Calendonia and Kerguelen) and New Zealand.
The limits of the extended continental shelf beyond the exclusive economic zone, as shown on this map, are as submitted for consideration of the United Nations Commision on the Limits of the Continental Shelf (CLCS). In accordance with Australia's request the CLCS has indicated that it will not consider the extended continental shelf appurtenant to the Australian Antarctic Territory for the time being.
This map shows the extent of Australia's maritime boundaries, stretching from Heard and McDonald Islands in the west to Norfolk Island in the east, and from the Torres Strait and Arafura Sea in the north to the Australian Antarctic Territory in the south.

MRTAS Mt Lloyd tmi 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 MRTAS Mt Lloyd tmi grid geodetic has a cell size of 0.00051 degrees (approximately 49m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1982 by the TAS Government, and consisted of 774 line-kilometres of data at 500m line spacing and 175m terrain clearance.

A Stratigraphic Reconstruction of Bulk Volatile Chemistry from Fluid Inclusions in: Barnicarndy-1/Waukarlycarly-1

A regional hydrocarbon prospectivity study was undertaken in the onshore Canning Basin in Western Australia as part of the Exploring for the Future (EFTF) program, an Australian Government initiative dedicated to driving investment in resource exploration. As part of this program, significant work has been carried out to deliver new pre-competitive data including new seismic acquisition, drilling of a stratigraphic well, and the geochemical analysis of geological samples recovered from exploration wells.
A regional, 872 km long 2D seismic line (18GA-KB1) acquired in 2018 by Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA), images the Kidson Sub-basin of the Canning Basin. In order to provide a test of geological interpretations made from the Kidson seismic survey, a deep stratigraphic well, Barnicarndy 1, was drilled in 2019 in a partnership between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) in the Barnicarndy Graben, 67 km west of Telfer, in the southwest Canning Basin.
Drilling recovered about 2100 m of continuous core from 580 mRT to the driller’s total depth (TD) of 2680.53 mRT. An extensive analytical program was carried out to characterise the lithology, age and depositional environment of these sediments. Geoscience Australia commissioned a fluid inclusion stratigraphy (FIS) study in 2020 on downhole samples in Barnicarndy 1. Here, volatile components ostensibly trapped with fluid inclusions are released and analysed revealing the level of exposure of the well section to migrating fluids. FIS analysis was performed on a total of 24 cuttings and 156 cores between 240 metres and 2679.1 metres base depth (Grant Group to Yeneena Basin Basement). The results of the study are found in the accompanying documents and can also be accessed through the Western Australian Petroleum and Geothermal Information Management System (WAPIMS) platform (https://wapims.dmp.wa.gov.au/WAPIMS/Search/Wells).

Ages of granites and associated mineralisation in the Herberton tinfield of northeast Queensland

Rb-Sr isotopic data reveal a close temporal association between ore deposits and the emplacement of Upper Palaeozoic granitic intrusions in the Herberton tinfield of northeast Queensland. Three main granite types are present: Elizabeth Creek type, consisting mainly of leucocratic biotite adamellite and ranging in age from 292 or 299 m.y. to 320 m.y.; Herbert River type, mainly granodiorite and isotopically dated at 278 to 315 m.y.; and 280 m.y. old Mareeba type, which consists mainly of biotite adamellite. Six mineralising events have been detected, all but the youngest being related to Elizabeth Creek Granite. The oldest, about 320 m.y. ago, was associated with intrusion of apparently small granite bodies southwest and southeast of Irvinebank. The next, at 314 m.y., accompanied the intrusion of the main mass of Elizabeth Creek Granite in the Emuford-Watsonville-Coolgarra area. A slightly later event, at 309 m.y., was associated with the emplacement of petrographically similar granite near Herberton. Mineralisation in the Wolfram Camp and Bamford Hill areas appears to have taken place about 303 m.y. ago. All of these events were characterised by greisen formation. A subsequent mineralisation in the Herberton area, at about 297 m.y., is related to a fine-grained phase of Elizabeth Creek Granite, and is characterised by chloritic alteration. The youngest dated event, in which hydrothermal alteration led to the production of fine-grained green biotite, occurred at about 284 m.y., and may be related to an intrusion of Mareeba-type granite. None of the major economic products (Sn, W, Cu, Pb, Ag) were confined to a single mineralising event: tin deposits, for example, were formed during at least five of the six episodes, and tungsten during at least four.

AUSGeoid98 v.1.0 data files:  (sl52)

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.

Hydrogeology of Australia

The hydrogeological map of Australia has been compiled at a scale of 1:5 000 000 according to the guidelines of the international legend for hydrogeological maps adapted for the unique conditions of the Australian continent. The map shows aquifer type, lithology, salinity, potentiometry, and groundwater flow directions, and major groundwater abstraction sites. The hydrogeology of the Australian continent is described in terms of principal aquifers, defined as those producing the best-quality water at highest yield from the shallowest depth. Aquifers are defined as porous or fissured, and subdivided in terms of their extent and productivity; these aspects are shown in solid colour on the map. Subsidiary aquifers are indicated for certain layered systems in major sedimentary basins. Groundwater salinity is indicated by a line representing 1500 mg L _ 1 total dissolved solids, the Australian limit for drinking water. Further subdivision of saline waters is shown on an inset map. The potentiometric surface, general directions of groundwater flow, and groundwater discharge features are shown where information is available. Some important man-made features are also shown, including abstraction sites and locations of the emerging problems of groundwater pollution and salinisation. Inset maps show elements of the Australian hydrogeological environment: topography, annual rainfall deficit, and drainage and runoff. Major hydrogeological divisions of the continent are the large sedimentary basins, fractured-rock provinces, and the overlying surficial aquifers. Large unexploited groundwater resources are held in some of the sedimentary basins and surficial aquifers.

Outer Darwin Harbour Marine Survey 2015: Sediment oxygen demand data on seabed sediments

This resource contains surface sediment data for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program 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:

1.   Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay;
2.   Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and 
3.   Collect tidal data for the survey area.

Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. This dataset comprises sediment oxygen demand measurments made on seabed sediments.

A detailed account of the survey is provided in: Siwabessy, P.J.W., Smit, N., Atkinson, I., Dando, N., Harries, S., Howard, F.J.F., Li, J., Nicholas, W.A., Potter, A., Radke, L.C., Tran, M., Williams, D. and Whiteway, T., 2015.
