Gravity 1997, Kooline, Wannery Creek, Andes, Brumby Creek A54282 (P199763), 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 Gravity 1997, Kooline, Wannery Creek, Andes, Brumby Creek A54282 (P199763) contains a total of 1480 point data values acquired at a spacing between 500 and 1000 metres. The data is located in WA and were acquired in 1997, under project No. 199763 for CRA Exploration Pty Ltd.

AUSGeoid98 v.1.0 data files: Barrow Creek (sf530-06)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

Australian Petroleum Blocks 2001a - Geodatabase

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts.
The international, scheduled areas and coastal waters used in this dataset are those found in the historical Australian Maritime Boundary Dataset 2006 (AMB2006). This version contains a number of technical amendments made on the basis of user feedback. These include:

Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51
The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.

The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset.
The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.
Existing production licences AC/P17, AC/RL4, and AC/RL5 are included in the dataset.
The blocks are attributed with fields containing information on:
- Parent 1 Million Mapsheet
- Offshore Area
- Epoch of the boundaries used to cut the data  AMB2001
- Datum
- Origin of the mapsheet in AGD66
- The position of all vertices in the block
- The number of vertices in the block
- The area of the block in acres
- The area of the block in hectares
The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

Ringarooma deep leads seismic refraction survey, Tasmania 1957

A seismic refraction survey was made by the Bureau of Mineral Resources in the Ringarooma district over four traverses chosen by Rio Tinto Australian Exploration Pty Ltd to test for the presence of buried channels in the bedrock, which may contain deep leads carrying cassiterite in economic amounts. The results gave no reliable indications of the presence of such channels, and it appears that geophysical methods are not likely to provide useful indications in this area. The Only possibility of using geophysical methods effectively to assist in prospecting the Ringarooma deep lead would be to make surveys as far to the south as possible.

ALF Compatible Laboratory UV Fluorescence Spectra of 120 Offshore Western Australia Oils Vol 1,2a,2b and CDROM

As part of AGSO's commitment to advancing exploration technology, the Petroleum and Marine Division has been conducting studies into the use of fluorescence signatures as a means of detecting, mapping and typing hydrocarbon seeps to their sources.  AGSO's aim is to provide data that will allow sea surface hydrocarbon anomoloies, detected during Airborne Laser Fluorosensor (ALF) surveys, to be correlated with oils and ultimately characterise the anomolies directly to their source.
This report concludes the first stage of AGSO's 'remote sensing' multi-client study and comprises ultra-violet fluorescence (UVF) emission spectra of 120 open file western Australian oils.  Aliquots of oil samples diluted with n-hexane were analysed by UVF to evaluate the type and quantity of aromatic hydrocarbons present in the samples.  The laboratory UVF data were collected by scanning the 280-500 nm emission response of oils using an excitation wavelength of 266 nm as employed by the ALF system currently being operated by World Geoscience Corp. Ltd.
The purpose of this report is to enable industry to make a comparison of UVF spectra of known oils with ALF surveys carried out off western Australia.  The oils included in this report represent all known offshore western Australian petroleum systems (Table 1) as defined by Bradshaw (1993) and Bradshaw et al.  (1994, 1997) and are compatible with those oils analysed in The Oils of Western Australia study (AGSO and GeoMark Research, 1996).
This report is designed as a stand alone product, with supplementary geological and geochemical information being incorporated from The Oils of Western Australia study (ibid) and published papers.

Geological Framework of the Southern Lord Howe Rise/West Norfolk Ridge Region: Cruise Proposal

The Lord Howe Rise region is an enormous area of complex seabed lying 500-1500 km east of
Australia. It includes relatively shallow water features such as the Lord Howe Rise, and the
Norfolk, West Norfolk and Dampier Ridges, and intervening deeper water areas such as the LordHowe, Middleton and New Caledonia Basins. Based upon the UN Law of the Sea Convention,
Australia has a large seabed claim in this region because of Lord Howe, Norfolk and PhilipIslands, which are Australian territory and would all generate 200 nautical mile Exclusive
Economic Zones and related 'legal' Continental Shelf areas. There is a negotiated seabed boundaryin the north separating French and Australian territory, but as yet there is no negotiated seabed
boundary separating New Zealand and Australian territory in the south.
Owing to its vast size, many features within the Lord Howe Rise region remain sparsely covered
by seismic data. Analysis of available data has defined several areas that may have long-termpetroleum potential. The most significant of these are the rift system beneath the western Lord
Howe Rise, the New Caledonia basin and the Taranui Sea Valley area of the southern NorfolkRidge.
The Australian Geological Survey Organisation (AGSO - formerly the Bureau of MineralResources, BMR) Project 121.30 (Lord Howe Rise and Norfolk Ridge 'Law of Sea' Study) seeks
to improve our understanding of the geological framework of the southern part of the Lord HoweRise region in the vicinity of the Australia/New Zealand seabed boundary zone. Its major
objectives are:
1) To investigate the structure, stratigraphy and basin development of the southern Lord Howe
Rise, southern New Caledonia Basin, and West Norfolk Ridge in the Australia/New Zealandseabed boundary zone.
2) To assess the resource potential of the major structural features within the region.
3) To determine the tectonic framework, crustal characteristics and evolution of the region, andattempt to understand the processes that have produced narrow strips of thinned and extended
continental lithosphere ("ribbon continents"), separated by narrow ocean basins.
4) To acquire data to assist with the definition of Australia's 'legal' Continental Shelf on thesouthwestern margin of Lord Howe Rise.
To address these objectives it is proposed that RV Rig Seismic be used to acquire approximately 3250 km of multichannel seismic and associated geophysical data, and conduct dredging
operations, during a cruise in the southern Lord Howe Rise/West Norfolk Ridge region (Survey114). The seismic data will be recorded on eight lines (including four very long regional lines)
using a 3000 m streamer (120 x 25 m groups), 49 litre sleeve gun arrays, 16 second records, and
30-fold coverage.

Clarence Richmond magnetic 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 Clarence Richmond magnetic grid geodetic has a cell size of 0.0005 degrees (approximately 52m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1996 by the NSW Government, and consisted of 48370 line-kilometres of data at a line spacing between 200m and 1600m, and 80m terrain clearance.

Forbes total count 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 Forbes total count grid geodetic has a cell size of 0.00083 degrees (approximately 85m) and shows the terrestrial dose rate of the Forbes Detail, NSW, 1993. The data used to produce this grid was acquired in 1993 by the NSW Government, and consisted of 49055 line-kilometres of data at a line spacing between 200m and 400m, and 100m terrain clearance.

Deep Seismic Reflection Profiling in the NE Yilgarn: Imlications for the Yilgarn's Crustal Architecture and Mineral Potential

Deep-seismic reflection data have provided information on the crustal architecture of several highly mineralised regions within the Archaean northeastern Yilgarn Craton, Western Australia.  These seismic data are characterised by several prominent features and include 1) a change in the thickness of the crust across the northeastern Yilgarn Craton, 2) subdivision of the crust into three broad layers, 3) a prominent east dip to the majority of the reflections, and 4) the identification of three east-dipping crustal-penetrating shear zones.  These east-dipping shear zones divide the region into four terranes and are surprisingly similar in geometry.  In the hangingwalls of the shears, there is evidence of a marked increase in deformation adjacent to the shear zone.  This region is underlain by another low-angle shear zone at depth.  Major orogenic Au deposits in the northeastern Yilgarn are spatially associated with major structures.  The Laverton Tectonic Zone, for example, is a highly mineralised corridor that contains several world-class Au deposits plus many other smaller deposits.  Other non crustal-penetrating structures within the area do not appear to be as well endowed as the Laverton structure.  We infer that the complex deformed region within the hangingwall and underlain by a low-angle shear zone forms a wedge-shaped trap with upward and/or sub-horizontal moving fluids being focused into the apex of the wedge.
