Application of the Theory of General Relativity to the reduction of geodetic VLBI data

In this paper we present an alternate formula for calculating gravitational time delay. We use this formula to reduce geodetic  Very Long Baseline Interferometry (VLBI) data, taking into account  gravitational effects within the Solar System, and to test general relativity. The alternate formula is obtained by expanding the
  conventional formula in a Taylor series. We show that the gravitational delay can be split into two terms: a geometric coordinate term; and a term that is explicitly linked to the light deflection angle. Our formula is  compared numerically to the  conventional formula and arrival times within 1 ps are found at 1$^\circ$ from the Sun for a full range of baseline lengths. We  conclude that the standard reduction of geodetic VLBI data for the effects of general relativity is equivalent to the displacement of the reference radio sources from their original catalogue positions in accordance with the classical light deflection formula across the whole sky.

Notes on fluctuation of water level at Lake George

As a result of abnormal rains in 1950, a considerable body of water has been impounded in Lake George, situated in New South Wales, but only 20 miles north of Canberra, Australian Capital Territory. Local reports claim a depth of water of 30 feet in the Lake and these reports have prompted the Advisory Council of the Australian Capital Territory to investigate the possibility of developing the lake as a recreational resort. As a first step in this investigation the Council has asked the Bureau of Mineral Resources, Geology and Geophysics for an opinion as to how long a considerable body of water may be retained in the lake.

Bulk Oils Database Table

The bulk oils database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases for the bulk properties of petroleum liquids (e.g., condensate, crude oil, bitumen) sampled from boreholes and field sites. The analyses are performed by various laboratories in service and exploration companies, Australian government institutions, and universities using a range of instruments. Petroleum is composed primarily of hydrocarbons (carbon and hydrogen) with minor quantities of heterocyclic compounds containing either nitrogen, oxygen or sulfur. Data includes the borehole or field site location, sample depth, shows and tests, stratigraphy, analytical methods, other relevant metadata, and various data types including; API gravity, elemental composition and photographs of the samples. The stable carbon (13C/12C) and hydrogen (2H/1H) isotopic ratios of crude oil and derivative saturated and aromatic hydrocarbon fractions are presented in parts per mil (‰) and in delta notation as &delta;13C and &delta;2H, respectively. Results are also included from methods that separate crude oils into bulk components, such as the quantification of saturated hydrocarbon, aromatic hydrocarbon, resin, and asphaltene (SARA) fractions according to their polarity.

These data provide information about the petroleum fluid’s composition, source, thermal maturity, secondary alteration, and fluid migration pathways. They are also useful for enhanced oil recovery assessments, petroleum systems mapping and basin modelling. Hence, these sample-based datasets are used for the discovery and evaluation of sediment-hosted resources. Some data are generated in Geoscience Australia’s laboratory and released in Geoscience Australia records. Data are also collated from destructive analysis reports (DARs), well completion reports (WCRs), and literature. The bulk oils data are delivered in the Petroleum Bulk Properties and Stable Isotopes web services on the Geoscience Australia Data Discovery Portal at https://portal.ga.gov.au which will be periodically updated.

Uranium ore-forming systems of the Lake Frome region, South Australia: Regional spatial controls and exploration criteria

Cenozoic basins of the Lake Frome region in South Australia contain most of Australia's known resources of sandstone-hosted uranium mineralisation. In addition to the currently operating Beverley uranium mine, two other deposits have been approved for mining (Honeymoon, Four Mile East) and discoveries continue to be made in the region (e.g., Beverley North; Heathgate Resources, announcement September 2009). While the known resources are significant, the potential of the region for very large uranium deposits has not been well understood, in part because of limited knowledge of the regional and district scale geological controls on uranium mineralisation.
The multidisciplinary study reported herein applies a 'mineral systems' approach to identify and map the principal geological controls on the location of known uranium mineralisation in the Lake Frome region. This new framework is aimed at providing a basis for refined exploration targeting of areas with potential for major undiscovered deposits, thus reducing investment risk for the exploration industry.
There are two resources available.

Ulladulla, NSW, 1976 (P435), magnetic line data, AWAGS levelled

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.
 These line dataset from the Ulladulla, NSW, 1976 survey were acquired in 1976 by the NSW Government, and consisted of 8077 line-kilometres of data at 1500m line spacing and 500m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Frome potassium 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 potassium grid has a cell size of 0.00083 degrees (approximately 86m) and shows potassium element concentration of the Frome, SA, Broken Hill Exploration Initiative, 1995 in units of percent (or %). The data used to produce this grid was acquired in 1995 by the SA Government, and consisted of 68300 line-kilometres of data at 400m line spacing and 80m terrain clearance.

BMR Maclean No1 stratigraphic drill hole, Clarence Moreton Basin

B.M.R. Maclean No. 1 was a fully cored stratigraphic hole drilled on the eastern margin of the Clarence-Moreton Basin near Evans Head. 
It reached a total depth of 664.8 m and intersected 590.05 m of Marburg Formation overlying 74.75 m of Ripley Road Sandstone. 
The lower 42.60 m of the Marburg Formation correlates with the Calamia Member recognised by Etheridge &amp; others (1985). 
The sequence is mostly multistorey fluvial channel sandstone with only a small proportion of fine grained facies so that potential hydrocarbon source rocks are rare. 
Porous sandstone is also rare, though parts of the Calamia Member and the Ripley Road Sandstone may be porous and permeable.

WA Margins Reconnaissance Survey (GA-2476) (ESP) - Multibeam Acoustic Backscatter Grid

This resource contains backscatter data acquired during the WA Margins Reconnaissance survey, GA-2476 from October 2008 to January 2009 onboard the RV Sonne as part of the Energy Security Program. Almost 230,000 kmÂ² of multibeam bathymetry was acquired over the duration of the survey including all transits. Seafloor features revealed by the backscatter and swath bathymetry have shown that geomorphology of the study areas is diverse. The continental slope of the west Australian margin study areas is characterised by large areas with numerous deeply incised canyons and areas with low-angle slumps and scarps mostly on the upper part of the slope. Other geomorphic features on the continental slope include short escarpments of local extent and small volcanic peaks over the Houtman Sub-basin part of the Perth margin. New bathymetry from the Cuvier Plateau has mapped large volcanic domes, some of them with terraces, ridges, a large previously unmapped valley and two large seamounts (newly named the Cuvier Seamount and the Wallaby seamount). See GA Record 2009/38 (Geocat# 69606) for further details on processing methods.

Carboniferous and Permian palynostratigraphy in Australia and Antarctica: a review

Continued research In late Palaeozoic palynological biostratigraphy In Australia since about 1970 permits the delineation of a series of informally defined palynostratigraphic units In both Western and eastern Australia. The units include both informal assemblage zones and taxon-range-zones. In the older, pre-glacial (and periglacial) part of the Carboniferous, two palynofloras, designated the Granulatisporite. frustulentus and the Secarisporites Microfloras are recognised. The Granulatisporites frustulentus Microflora is subdivided Into the Grandispora spiculifera Assemblage, of Tournaisian age, and the Anapiculatisporites largus Assemblage, which spans the early to late Visean Interval. The succeeding Secarisporites Microflora, the contents of which are incompletely described, is subdivided into three: the Grandispora maculosa, Anabaculites yberti, and Potonieisporites Assemblages. The Secarisporites Microflora characterises strata ranging in age from late Visean to perhaps Missourian. The preglacial palynofloras are best known from the Canning and Bonaparte Gulf Basins in Western Australia, but are known in eastern Australia from scattered localities in the Drummond Basin and the New England Block. For the later Carboniferous and Permian, palynostratigraphic schemes have developed independently in Western and eastern Australia. In Western Australia, the Canning Basin interval commencing with the glacials of the Grant Formation at the base, and extending to the top of the Liveringa Formation, has provided the stratigraphic standard for the definition of eight informal palynological assemblages, designated Units I to VIII. These span a time Interval approximately equivalent to the Missourian to late Guadalupian. In eastern Australia, the palynostratigraphic schemes currently in use represent modifications of the palynological Stages synthesised by Evans (1969). Subdivisions within these stages are based in most cases on the first appearances of individual form-species; two subdivisions have been described within both Stages 2 and 3, three within Stage 4, and four within Stage 5. Correlation of these new units with the assemblage units described from Western Australia is tentative at present. The subdivisions of Evans scheme have been identified within, inter alia, the Bowen, Cooper, Galilee, Sydney, and Tasmania Basins. Recent studies in Antarctica have compared palynological assemblages from the central Transantarctic Mountains and south Victoria Land with eastern Australian palynofloras: Stages 2, 4, and 5 have been identified from these areas. Assemblages from the Prince Charles Mountains have been referred to Stage 5.
