Tara-Surat Area Gravity (P196312), 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 Tara-Surat Area Gravity (P196312) contains a total of 114 point data values acquired at a spacing between 1200 and 1500 metres. The data is located in QLD and were acquired in 1963, under project No. 196312 for None.

Rift Evolution in the Capel and Faust Basins, Offshore Eastern Australia, and Implications for Regional Petroleum Prospectivity

The Capel and Faust basins are located on the northern Lord Howe Rise between eastern Australia and New Caledonia in water depths of 1300-2500 m. Under the Australian Government's New Petroleum (2003-2007) and Offshore Energy Security (2007-2011) programs, Geoscience Australia acquired new geological data including high quality 2D seismic data, high resolution multibeam bathymetry, gravity and magnetic data, and rock dredge samples. These data have been analysed and synthesised for a geological and petroleum prospectivity assessment of the area. Prior to this phase of data collection, geoscientific data was limited to regional seismic profiles acquired during the 1970s to 1990s, shiptrack potential field and bathymetric data, and one DSDP drill hole.
The interpretation of new data has improved definition of depocentres previously indicated by regional
satellite gravity data. The largest depocentres are approximately 150 km long and 40 km wide. Seismic data suggest that the basin fill attains a maximum total thickness of over 6 km and consists of two syn rift and one sag megasequence packages, overlying a pre rift basement. The basement includes an older (?Mesozoic) sedimentary succession and a possible rift precursor volcanic succession. The early syn rift megasequence (Syn rift 1) is inferred to be dominated by Early Cretaceous (or older) volcanics and volcaniclastic sediments. It may also include coaly and lacustrine sediments. The late syn rift megasequence (Syn rift 2) is likely to be dominated by Late Cretaceous non marine clastic sediments, with localised volcanics and coal. The upper part of this megasequence was deposited under increasingly marine influence and is likely to include deltaic and shoreline sandstones. The post rift megasequence is essentially a Late Cretaceous to Recent deepeningupward marine succession that becomes increasingly calcareous and fine grained.

ASTER Mineral Index Processing Manual

ASTER Mineral Index Processing Manual, Complied by Aleks Kalinowski and Simon Oliver, October 2004.
ASTER is the Advanced Spaceborne Thermal Emission and Reflection Radiometer, a multi-spectral sensor onboard one of NASA's Earth Observing System satellites, Terra, which was launched in 1999. ASTER sensors measure reflected and emitted electromagnetic radiation from Earth's surface and atmosphere in 14 channels (or bands). There are three groups of channels: three recording visible and near infrared radiation (VNIR), at a spatial resolution of 15m; six recording portions of shortwave infrared radiation (SWIR) at a spatial resolution of 30m; and five recording thermal infrared radiation (TIR) at a resolution of 90m. The higher spectral resolution of ASTER (compared to Landsat, for example - Fig.1) especially in the shortwave infrared region of the electromagnetic spectrum makes it possible to identify minerals and mineral groups such as clays, carbonates, silica, iron-oxides and other silicates. An additional backward-looking band in the VNIR makes it possible to construct digital elevation models from bands 3 and 3b. ASTER swath width is 60km (each scene is 60 x 60km) which makes it useful for regional mapping.

Petroleum Prospectivity of the East Malita Graben Area, Bonaparte Basin

Release Areas NT92-1 and NT92-2 comprise 138 blocks and 133 blocks respectively, located in the northeastern part of the Bonaparte Basin, approximately 300 kilometres northwest of Darwin. The release areas overlie the eastern part of the Malita Graben, the Sahul Platform to the north, and the margin of the Darwin Shelf to the south. In this study, most of the lines from WMC's 1985 Marie Seismic Survey were used to provide a grid of about 20 x 30 kilometres over most of the two release areas. Three lines from WMC's 1987 Connie Seismic survey and two lines from ARCO Australia Limited (ARCO)'s 1972 Baldwin Bank Seismic Survey were also used to infill some detail. Twenty interpreted lines are included in the prospectivity package. Four key horizons were eventually mapped: top Cretaceous, Turonian marker, Albian/Aptian Unconformity and the Callovian ('Breakup') Unconformity. On some lines, the probable top Permian or Triassic is mapped in part, but this horizon is unreliable as there is no well control. Control for the other horizons was provided by Shearwater I, Heron 1 and Evans Shoal. The Albian/Aptian Unconformity provides a very strong regional marker at about 2 to 2.5 secs (TWT), resulting from a seismic contrast between the overlying basal Bathurst Island Group carbonates and underlying Flamingo Group sands/shales. At least five play types have been identified in the release areas. Most are associated with fault-dependent anticlines or horst blocks within the Malita Graben and Sahul Platform. This study demonstrates that in this area of nearly 23 000 square kilometres, which, by modern standards, has generally inadequate seismic coverage with relatively poor quality data, there are numerous targets remaining to the evaluated, many of which require only minimal work to be brought up to prospect status. As the region has known hydrocarbon occurrences, the results of this study indicate that Areas NT92-1 and NT92-2 should be considered to be highly prospective.

Integration of magnetotelluric and deep seismic data to map crustal architecture in the Mt Isa region, Northern Australia Implications for Mineral Prospectivity

Mount Isa Province in northern Australia is one of the world's most strongly endowed regions for base metals and host to major iron-oxide-copper-gold (IOCG) deposits. The Carpentaria Conductivity Anomaly at the eastern margin of the Province is a major electrical conductivity structure of the Australian continent. We have used magnetotelluric and deep seismic reflection data to image the crustal architecture in this complex region to understand the crustal-scale fluid pathways and potential mineral occurrences. The resistivity models reveal a number of prominent crustal-scale conductors, suggesting that the Carpentaria Conductivity Anomaly is likely caused by a series of isolated or interconnected bodies. These conductors characterise the position and geometry of the ancient Gidyea Suture Zone, interpreted as a west-dipping subduction zone. The conductivity anomaly may record the activity of fluid hydration involved during a subduction event, with the enhanced conductivity likely being caused by deformation or mineralisation of graphitic or sulfidic rocks during orogensis. The distribution of known gold and copper deposits shows a close spatial correlation with the suture zone, suggesting that this structure is potentially a fundamental control on IOCG deposits in its vicinity. The interpretation of the seismic image shows a good correlation with the resistivity models. The implication is that crustal-penetrating structures act as potential pathways for fluid movement to form mineral deposits in the upper crust. The significance of mapping such structures using geophysics is highlighted for mineral exploration.
