Report on the Analysis of the Asia Pacific Regional Geodetic Project (APRGP) GPS Campaign 2013

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an important activity of the Geodetic Reference Frame for Sustainable Development Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). This document overviews the data analysis of the APRGP GPS campaign undertaken in 2013. The GPS data were processed using version 5.0 of the Bernese GPS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2008 reference frame through adopting IGb08 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products.

Glengarry Peak Hill Robinson Range Areas ABCD 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 Glengarry Peak Hill Robinson Range Areas ABCD magnetic grid geodetic has a cell size of 0.00083 degrees (approximately 88m). The units are in nanoTesla (or nT). 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.

An Isotopic Atlas of Australia: Foundational data for integrated geoscience through time and space

Australia has been, and continues to be, a leader in isotope geochronology and geochemistry. While new isotopic data is being produced with ever increasing pace and diversity, there is also a rich legacy of existing high-quality age and isotopic data, most of which have been dispersed across a multitude of journal papers, reports and theses. Where compilations of isotopic data exist, they tend to have been undertaken at variable geographic scale, with variable purpose, format, styles, levels of detail and completeness. Consequently, it has been difficult to visualise or interrogate the collective value of age and isotopic data at continental-scale. Age and isotopic patterns at continental scale can provide intriguing insights into the temporal and chemical evolution of the continent (Fraser et al, 2020).
As national custodian of geoscience data, Geoscience Australia has addressed this challenge by developing an Isotopic Atlas of Australia, which currently (as of November 2020) consists of national-scale coverages of four widely-used age and isotopic data-types:
4008 U-Pb mineral ages from magmatic, metamorphic and sedimentary rocks
2651 Sm-Nd whole-rock analyses, primarily of granites and felsic volcanics
5696 Lu-Hf (136 samples) and 553 O-isotope (24 samples) analyses of zircon
1522 Pb-Pb analyses of ores and ore-related minerals 
These isotopic coverages are now freely available as web-services for use and download from the GA Portal. While there is more legacy data to be added, and a never-ending stream of new data constantly emerging, the provision of these national coverages with consistent classification and attribution provides a range of benefits:
vastly reduces duplication of effort in compiling bespoke datasets for specific regions or use-cases
data density is sufficient to reveal meaningful temporal and spatial patterns
a guide to the existence and source of data in areas of interest, and of major data gaps to be addressed in future work
facilitates production of thematic maps from subsets of data. For example, a magmatic age map, or K-Ar mica cooling age map
sample metadata such as lithology and stratigraphic unit is associated with each isotopic result, allowing for further filtering, subsetting and interpretation.
The Isotopic Atlas of Australia will continue to develop via the addition of both new and legacy data to existing coverages, and by the addition of new data coverages from a wider range of isotopic systems and a wider range of geological sample media (e.g. soil, regolith and groundwater).

AUSGeoid98 v.1.0 data files: Mallacoota (sj55-08)

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.

Australia's Identified Mineral Resources 1999

In 1998, Australia's economic demonstrated resources (EDR) of cobalt, copper, magnesite, gold,
ilmenite, nickel, platinum group metals, tantalum and vanadium increased while those of diamond,
iron ore, lead, manganese ore, lithium, silver, uranium, tin and zinc diminished. The reductions in EDR were due mainly to ongoing high levels of production; commodity prices were a subsidiary factor. EDR of all other commodities remained essentially unchanged.
EDR of nickel and tantalum reached record levels in 1998. Gold increased slightly and maintained a flattening-off trend in EDR that has been evident since the mid-1990s. Black coal and bauxite EDR remained around levels established in the late 1980s and mid-1990s respectively. A decrease of almost 8% in iron ore EDR is attributable to production and a comprehensive review of resources  information that became available during the year.
Australia continues to rank highly as one of the world's leading mineral resource nations. It has the world's largest EDR of lead, mineral sands (ilmenite, rutile, and zircon), nickel, silver, tantalum, uranium and zinc. In addition, its EDR is in the top six worldwide for bauxite, black coal, brown coal,
copper, cobalt, gold, iron ore, lithium, manganese ore, rare earth oxides, industrial diamond and vanadium.

National ASTER Map AlOH group composition


Band ratio: B5/B7 Blue is well ordered kaolinite, Al-rich muscovite/illite, paragonite, pyrophyllite Red is Al-poor (Si-rich) muscovite (phengite)
useful for mapping: (1) exposed saprolite/saprock is often white mica or Al-smectite (warmer colours) whereas transported materials are often kaolin-rich (cooler colours); (2) clays developed over carbonates, especially Al-smectite (montmorillonite, beidellite) will produce middle to warmers colours. (2) stratigraphic mapping based on different clay-types; and (3) lithology-overprinting hydrothermal alteration, e.g. Si-rich and K-rich phengitic mica (warmer colours). Combine with Ferrous iron in MgOH and FeOH content products to look for evidence of overlapping/juxtaposed potassic metasomatism in ferromagnesian parents rocks (e.g. Archaean greenstone associated Au mineralisation) +/- associated distal propyllitic alteration (e.g. chlorite, amphibole).

Enhanced Oil Recovery Potential Basins

This dataset shows the key Australian petroleum producing basins ranked by their potential for CO2 enhanced oil recovery (CO2-EOR), based on a study completed by Geoscience Australia in 2020. Basin rankings result from the assessment of six parameters: the API gravity of the oil, temperature, pressure, reservoir quality (porosity, permeability), nearby CO2 sources and existing infrastructure. Higher rankings indicate greater potential for CO2-EOR. For further information see: Tenthorey, E., and Kalinowski, A. 2022. Screening Australia’s Basins for CO2-Enhanced Oil Recovery.
