Glengarry Peak Hill Robinson Range Areas ABCD 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 0.00083 degrees (approximately 88m) and shows uranium element concentration of the Glengarry, Peak Hill, Robinson River(pt), GSWA,1994 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 118765 line-kilometres of data at 400m line spacing and 60m terrain clearance.

AUSGeoid98 v.1.0 data files:  (sk52-12)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

Shelley Ordovician strata at the Belubula River, near Canowindra, New South Wales

The Ordovician age of the limestone at the Belubula River was recognized by the present writer from fossils collected by Mr. N.C. Stevens, University of Sydney. Thought, in the opinion of A.A. Opik, the first collection examined was completely convincing, Mr. Stevens approached the Chief Geologist, Dr. N.H. Fisher, early in 1951 for further support in the field. It was then decided that A.A. Opik, being responsible for the age-determination of the fossils from the Belubula River, Cliefden Caves area, would accompany Mr. Stevens on a field excursion to collect more evidence for the age of the limestones and to look for an occurrence of Silurian fossils in the same area. The results of this examination are given in this report, comprising a description of the Ordovician sequence, and a summary of the stratigraphy and correlation of the Ordovician Belubula River.

Northern Star Gravity (P199011), 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 Northern Star Gravity (P199011) contains a total of 806 point data values acquired at a spacing of 50 metres. The data is located in NT and were acquired in 1990, under project No. 199011 for None.

Isotopic Atlas of Australia. An Update;  (SGGMP conference, 2022)

The first iteration of a continental-scale Isotopic Atlas of Australia was introduced by Geoscience Australia at the 2019 SGGMP conference in Devonport, Tasmania, through a talk and poster display. In the three years since, progress on this Isotopic Atlas has continued and expanded datasets are now publicly available and downloadable via Geoscience Australia’s Exploring for the Future (EFTF) Geochronology and Isotopes Data Portal.
This poster provides example maps produced from the compiled data of multiple geochronology and isotopic tracer datasets, now available in the EFTF Portal. Available data include Sm–Nd model ages of magmatic rocks; Lu–Hf isotopes from zircon and associated O-isotope data; Pb–Pb isotopes from ore-related minerals such as galena and pyrite; Rb–Sr isotopes from soils; U–Pb ages of magmatic, metamorphic and sedimentary rocks; and K–Ar, Ar–Ar, Re–Os, Rb–Sr and fission-track ages from minerals and whole rocks. Compiled geochronology, which commenced with coverage of northern Australia, is now much more comprehensive across Victoria and Tasmania, with New South Wales and South Australia updates well underway.
This Isotopic Atlas of Australia provides a convenient visual overview of age and isotopic patterns reflecting geological processes that have led to the current configuration of the Australian continent, including progressive development of continental crust from the mantle. These datasets and maps unlock the collective value of several decades of geochronological and isotopic studies conducted across Australia, and provide an important complement to other geological maps and geophysical images—in particular, by adding a time dimension to 2D and 3D maps and models.
To view the associated poster see eCat 147377.
This Abstract &amp; Poster were presented to the 2022 Specialist Group in Geochemistry, Mineralogy and Petrology (SGGMP) Conference 7-11 November (https://gsasggmp.wixsite.com/home/biennial-conference-2021)

GSWA Musgrave Extensions 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.

Summary of Analyses undertaken on debris recovered during the search for flight MH370

On 8 March 2014, the Boeing 777-200ER aircraft registered as Malaysia Airlines 9M-MRO and operating as flight MH370 (MH370) disappeared from air traffic control radar after taking off from Kuala Lumpur, Malaysia on a scheduled passenger service to Beijing, China with 227 passengers and 12 crew on board.
After analysis of satellite data it was discovered that MH370 continued to fly for over six hours after contact was lost. All the available data indicates the aircraft entered the sea close to a long but narrow arc of the southern Indian Ocean.
On 31 March 2014, following an extensive sea and air search, the Malaysian Government accepted the Australian Government’s offer to take the lead in the search and recovery operation in the southern Indian Ocean in support of the Malaysian accident investigation.
On behalf of Australia, the Australian Transport Safety Bureau (ATSB) coordinated and led the search operations for MH370 in the southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB in sea floor mapping (bathymetric survey) and the underwater search. GA has also provided quarantine facilities for receipt of possible debris, and has undertaken laboratory analyses for a number of these pieces. This record is a collation of reports describing quarantine procedures and parts analysis undertaken by Geoscience Australia for some of the debris recovered and processed through Geoscience Australia laboratories during the search for flight MH370.
