New Norcia traverse, Gravity (P199360), 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 New Norcia traverse, Gravity (P199360) contains a total of 262 point data values acquired at a spacing between 350 and 600 metres. The data is located in WA and were acquired in 1993, under project No. 199360 for Geological Survey of Western Australia (GSWA).

The molluscan fauna and probable Lower Cretaceous age of the Nanutarra Formation of Western Australia

Mollusca from the Nanutarra Formation, a recently defined strata! unit cropping out along the north-eastern edge of the Carnarvon Basin of Western Australia, are described and the age of the' formation is discussed. The fossils occur largely as moulds of the original shells, so that their study has been based mainly on artificially prepared casts. Of about 48 forms recorded in the paper, only one (Pseudavicula anomala) has been definitely referred to a previously described species, four (Maccoyella aff. corbiensis. M. aff. barklyi, M. aff. moorei, and Modiolus aff. ensi/ormis) have been assigned qualified identifications with known species, and 18 are described as new; the remainder have been given only generic identifications, owing to the limitations of the material. The new species are as follows:-Nuculana hoelscheri, Glycymeris mckellari, Pacitrigonia? nanutarraensis, Pterotrigonia australiensis, "[socyprina" fairbridgei, "Corbicellopsis," nanutarraensis, Lucina macroporum, Mutiella? teicherti, Protocardia wapeti, Astarte (Nicaniella) mcwhaei, Eriphyla playjordi, Pleuromya ashburtonensis, Panopea glaessneri. CQrbula nanutarraensis, Muricotrochus? australiensis, Purpurina? yanreyensis, Procerithium (Rhabdocolpus) brunnschweileri, and" Acteonina" australiensis. Apart from the species of Pseudavicula, Maccoyella, and Modiolus, which have been identified, mostly with qualification, with Australian Lower Cretaceous species, the fossils bearing particularly on the age of the formation are those belonging to the genera Pterotrigonia (hitherto solely Cretaceous apart from one record from the Tithonian), Eriphyla (hitherto mainly Cretaceous, but known from the Upper Jurassic), Glycymeris (known from the Cretaceous but not from the Jurassic), and large Panopea (resembling several Cretaceous species and unlike any from the Jurassic). No species belongs to an exclusively Jurassic group. It is concluded that, notwithstanding palaeobotanical evidence of a Jurassic age, the Nanutarra Formation should be most probably referred to the Lower Cretaceous. It has yielded no ammonites or brachiopods.

AUSGeoid98 v.1.0 data files: Maryborough (sg56-06)

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.

Operational report on Broken Hill detailed airborne magnetic and gamma-ray spectormeter survey, 1975

In 1975, to obtain data to assist geological mapping by the Geological Survey of New South Wales and mineral exploration by mining companies, the Bureau of Mineral Resources flew a detailed airborne magnetic and radiometric survey of most of the area of Willyama Complex outcrop in the Broken Hill 1:250 000 Sheet area. This report describes the acquisition, processing, and presentation of the data, and figures the total magnetic intensity and radiometric contours and profiles now available.

Offshore Northern Perth Basin 2D and 3D Models of Depth to Magnetic Basement

During 2009-11 Geoscience Australia completed a petroleum prospectivity study of the offshore northern Perth Basin as part of the Australian Government's Offshore Energy Security Program. A significant component of the program was the acquisition of a regional 2D reflection seismic and potential field survey GA-310 in 2008/09, which has aided in furthering the understanding of basement within the northern Perth Basin.  Geologic basement in the northern Perth Basin, defined here to be Precambrian and older, is deep and generally not resolved in the reflection seismic data. However the GA-310 magnetic anomaly data combined with Geoscience Australia's magnetic ship-track database and magnetic anomaly grid allowed an assessment of depth to magnetic sources, and estimation of sediment thickness, providing new insight into basement depth and trends. New magnetic susceptibility measurements taken from core of offshore wells of the northern Perth Basin, seismic interpretation and depth to magnetic source estimates using the magnetic spectral method have been used to constrain 2.5D magnetic forward models.
These magnetic models indicate that intrusion of the deepest sediments by high-susceptibility bodies is probable. The reflection seismic evidence for these bodies is not clear, though in some cases they may be associated with faults and structural highs. Where the modelled bodies penetrate the sediments they are mostly below or within the Permian strata.  A moderate positive magnetic anomaly along the Turtle Dove Ridge is modelled in 2D by massive bodies whose tops are 5-15 km below sea floor. A depth to magnetic basement map highlights sub-basins and structural highs within the northern Perth Basin, and is shown to be a good first order approximation of sediment thickness and basin geometry.  For instance maximum sediment thicknesses of the Abrolhos, Zeewyck and Houtman sub-basins are shown to be 10, 13.5 and 12 km respectively.

Hydrogeology and groundwater resources of Nauru Island, Central Pacific Ocean

Nauru, in the central Pacific Ocean, is a raised atoll capping a volcanic seamount arising from an ocean floor depth of 4300m. The land area is 22km, and the island rises to 70m above sea level. Drilling has proved dolomitised limestone of upper Miocene or younger age to a depth of 55m below sea level. Gravity and magnetic surveys indicate that the limestone probably overlies volcanic bedrock at a depth of about 500m. 
Reverse-circulation drilling and geoelectrical probes indicate that there is a discontinuous freshwater layer averaging 5m thick beneath Nauru. This is underlain by a mixing zone of brackish water, 60-70m thick. The exceptional thickness of the mixing zone is ascribed to high permeability of the karstified limestone. The forthcoming cessation of phosphate mining will mean a shortfall in water supply which will probably have to be met by the desalination of brackish water. Groundwater beneath the mined-out area, and the settled coastal terrace, is highly vulnerable to pollution, and waste disposal management needs to be considered in relation to groundwater protection.
