Yilgarn Seismic Lines - Line 2 (P199912), 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 Yilgarn Seismic Lines - Line 2 (P199912) contains a total of 156 point data values acquired at a spacing of 280 metres. The data is located in WA and were acquired in 1999, under project No. 199912 for Australian Geological Survey Organisation (AGSO).

Guide to Using the Australian Proterozoic Mafic-Ultramafic Magmatic Events Map

To assist the mining industry during the current buoyant times of historically high nickel and platinum-group element prices, Geoscience Australia has produced two web-based map sheets (at 1:5 million and 1:10 million scales) that show the spatial distribution of Proterozoic (2500 Ma to 545 Ma) mafic-ultramafic magmatic events in Australia. The maps illustrate for the first time, the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and their associated mineral deposits. These rocks have been assigned to thirty Magmatic Events (ME) that range in age from the Early Palaeoproterozoic ~2455 Ma (ME 1) to the Early Cambrian ~520 Ma (ME 30).
Record 2008/15 (Geocat 66624) is a user guide for the `Australian Proterozoic Mafic-Ultramafic Magmatic Events' map (Geocat 66114). It compiles all the geological and geochronological data that underpins the information portrayed on the map. The key objectives of this user guide are to:
- summarise the scope, scientific rationale, and methodology of the study;
- describe the digital datasets (e.g., solid geology, geological province, geochronology, mineral resources, geophysics, etc) that underpin the information portrayed on the maps; and
- document the attribution data and publications used for characterising and assigning magmatic events to the Proterozoic mafic-ultramafic units.

Hann River Walsh 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 Hann River Walsh magnetic grid geodetic has a cell size of 0.00083 degrees (approximately 91m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1991 by the QLD Government, and consisted of 61810 line-kilometres of data at 400m line spacing and 100m terrain clearance.

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.

Application of sequence stratigraphic concepts to Middle Cambrian phosphogenesis, Georgina Basin, Australia

The stratigraphic and spatial distributions of phosphatic and organic-matter rich Middle Cambrian sediments of the Georgina Basin are outlined in terms of sequence stratigraphic concepts. This approach has permitted an integrated analysis of Middle Cambrian depositional patterns and their time constraints. It has also provided insights into aspects of the basins structure, the timing of subsidence of its primary Components, and frequency of relative sea level fluctuations. Middle to early Late Cambrian sediments of the Georgina Basin are interpreted to occur in two stratigraphic sequences. In each sequence phosphorites, phosphatic limestones and organic-matter rich shales comprise a suite of repeating lithofacies restricted to retrogradational parasequence sets of the transgressive systems tract. The position of facies within each transgressive systems tract depends on relative sea level, palaeogeography and palaeotectonics. In sequence 1 (early Middle Cambrian), phosphogenesis is related to gradual transgression of a continent with irregular palaeotopography.  Sequence 1a is interpreted to be of local significance, related to early subsidence of the Mt Isa Block during the late Ordian to early Templetonian.  A rapid fall in relative sea level terminated sediment accumulation in sequence 1 and led to the development of a subaerial exposure surface. Sediments of the transgressive systems tract in stratigraphic sequence 2 are of lateTempletonian to early Undillan age. Deposition in sequence2 ceased in the Mindyallan. Rocks of the transgressive systemstract occur in three retrogradational parasequence sets. Recognition of sequence boundaries has helped clarify lateralbiofacies, leading to improved reconstructions of thepalaeogeographic distribution of the phosphorites and organic-matter rich shales.

Deep-water Quaternary Foraminifera from short cores taken between Australia and southeast Indonesia

Twenty short cores were recovered from the northern Scott Plateau (water depths ca 3200 m) and the southern slope of the Java Trench (water depths 4950-5790 m) by R.V. Valdivia in 1977; selected cores have been studied in detail. About 55 species of benthonic foraminifera were identified on the plateau, but only half as many in the trench. Only deep-water forms occur in the trench, suggesting an absence of transport from shallower depths. Fragile agglutinating forms are confined to the surface sediments, or are totally absent. The planktonic foraminifera from the plateau generally belong to tropical associations. The assemblages show that the Holocene-Pleistocene boundary lies at about 60 cm in the cores, and that carbonate solution is more marked above than below the boundary.

Feasibility of underground hydrogen storage in a salt cavern in the offshore Polda Basin

Underground hydrogen storage (UHS) in halite caverns will become an essential technology to supplement energy supply networks. This study examines the feasibility of UHS in the offshore Polda Basin by integrating previous seismic interpretation, well data and regional geology information. The Mercury structure in the central – east Polda Basin has extensive halite accumulations (both vertically and laterally) and has been identified as an area with high UHS potential. The net halite thickness is more than 1000 m, while the total potential area is about 217 km². Well data from the Mercury 1 well show a low thermal gradient (1.7–2.1 °C/100m) and overburden pressure gradient of approximately 18 ppg, providing effective gas operation pressure for UHS. To illustrate the feasibility of UHS, a conceptual design of a halite cavern is provided for a depth range of 1650–2000 m. Caverns with diameters of 60 m and 100 m are estimated to have storage capacities of approximately 240 GWh and 665 GWh, respectively. Multiple halite caverns could be constructed within the extensive Mercury halite accumulation. Further investigation into the potential for salt accumulations in the onshore Polda Basin is recommended.
