MRTAS Weymouth Cape Portland uranium 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 uranium grid has a cell size of 0.001 degrees (approximately 98m) and shows uranium element concentration of the NETGOLD - Weymouth-Cape Portland, TAS, 1993 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1993 by the TAS Government, and consisted of 4309 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Regional crustal setting of iron oxide Cu-Au mineral systems of the Olympic Dam region, South Australia: insights from potential-field modeling

Detailed analysis and modeling of regional gravity and magnetic data from the Stuart Shelf around the Olympic Dam iron oxide copper-gold (IOCG) deposit, constrained by geologic observations obtained from deep drill cores, show that the eastern Gawler craton basement at 1.61 to 1.59 Ga consisted of an Archean core with two sequences of successively younger supracrustal rocks stepping out eastward from it. These were overprinted by the tectonothermal Hiltaba event. Forward models of potential-field data show no convincing evidence for the presence of widespread mafic rocks or extensional basin systems developed immediately prior to, or during, IOCG mineralization. The high intrusive level and sill-like geometry of Hiltaba Suite plutons emplaced immediately prior to IOCG mineralization is difficult to explain in terms of a genetic association with a dominantly extensional tectonic setting. Instead, the tectonic setting inferred from the basement architecture during mineralization is one of low-strain shortening, consistent with regional field observations. A case can be made for intrusion of the Hiltaba Suite in localized accommodation zones in an overall orogenic setting. This style of low-strain shortening (&lt;10%) is consistent with maximum rates and volumes of fluid flow in the upper crust, and access of these fluids to a variety of basement rock types to buffer metal-scavenging fluids. This fluid-driving mechanism does not necessitate a role for regional mafic magmatism and volcanism in the formation of IOCG deposits. Modeling of regional gravity and magnetic data is generally applicable to exploration for IOCG systems, and other mineral systems, in covered terranes that have distinctive geophysical signatures resulting from fluid-wall-rock redox geochemical reactions.

Brachiopods of the Murrumbidgee Group, Taemas, New South Wales

The Devonian limestones of the Taemas-Cavan area crop out in a northtrending synclinorium, about 25 km southwest of Yass and about 55 km northnorthwest of Canberra, in the southeastern part of New South Wales (Text-fig. 1). The Devonian rocks of this structure, consisting of limestone units of the Cavan and Taemas Formations and shale and sandstone of the Majurgong Formation, belong to the lower to upper Emsian (? to Eifelian) Murrumbidgee Group. The two units on which the work reported here concentrates, the 'Receptaculites' Limestone and the Warroo Limestone, were selected because they contain rich. and well preserved faunas. A comprehensive collection of brachiopods from part of the Murrumbidgee Group of the Yass area, New South Wales, confirms the late Emsian age of the upper part of the Group. They flourished in a shallow vigorous sea. Of the 46 species and subspecies described, belonging to 35 genera, 6 genera, 34 species, and the subspecies are new. It has been possible to trace the ontogeny of many species.

P1258 Browse Basin 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 P1258 Browse Basin TMI Grid Geodetic has a cell size of 0.00167 degrees (approximately 182m). The units are in nanoTesla (or nT).

Preliminary Evaluation of the Petroleum Potential of Australia's Central Eastern Margin

Australia's east coast north of Bass Strait has been very sparsely explored for petroleum. Exploration permits have been intermittently held over the offshore Sydney Basin, including an active permit at the time of writing, and some permits were held in north Queensland waters in the 1960s and 1970s, but much of the geology of this eastern continental margin is virtually unknown. This report provides a preliminary assessment of the petroleum potential of Australia's east coast, from the border between New South Wales and Victoria in the south, to the southern boundary of the Great Barrier Reef Marine Park (GBRMP) offshore southeast Queensland in the north. Petroleum exploration is prohibited within the GBRMP, and no assessment of this area is included in the report.
Palaeozoic basement rocks covered by a veneer of Cainozoic sediments underlie a large part of the study area (Figure 1). At least four sedimentary basins also underlie the continental shelf and probably the continental slope in the case of the Sydney and Maryborough Basins. These two basins are also the best known; but the Clarence-Moreton and Nambour Basins are also known to have offshore extensions on the shelf. It is also possible but not certain that the Ipswich and Lorne Basins could have offshore components, and there is some evidence of a pre-Clarence-Moreton Basin sedimentary sequence offshore of the Coffs Harbour area. In addition to these basins, several graben and half-graben associated with Tasman Sea rifting may occur within basement dominated shelf and slope areas - two of these features are known from very limited data.

Pacific Sea Level and Geodetic Monitoring Project Levelling & GNSS Monitoring Survey Reports: Yaren, Nauru, October 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.
Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.
This report provides the results of the GNSS monitoring survey &amp; high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Yaren, Nauru from 24th to 29th October 2019.  It also provides an updated height of the tide gauge derived from GNSS time series analysis and precise levelling observations.
