Cooper Basin North Gravity Complete Bouguer Anomaly geodetic

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 Cooper Basin North Gravity Complete Bouguer Anomaly geodetic is a complete Bouguer anomaly grid for the Cooper Basin North Gravity Survey, Queensland 2007 (P200701). This gravity survey was acquired under the project No. 200701 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 796m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 3550 gravity stations were acquired to produce this grid.

Report on the Analysis of the Asia Pacific Regional Geodetic Project (APRGP) GPS Campaign 2020

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). The WG continues to undertake an annual GPS campaign activity as some member countries are unable to participate in the Asia Pacific Reference Frame (APREF) project but have an ongoing requirement for geodetic positioning relative to a stable global/regional reference network. One of the roles of the WG is to create and maintain a densely realised and accurate geodetic framework, coordinate regional cooperation in geodesy amongst national agencies, and to build and improve the regional geodetic infrastructure. The APRGP is where UN-GGIM-AP member agencies contribute GPS data to the WG. GPS data from the APRGP are available for all participant member countries for local and global scientific research and local applications. The composite GPS data set is subsequently analysed by the WG to provide estimates of station coordinates in the International Terrestrial Reference Frame (ITRF). The results of the APRGP are also supplied by the WG to the official ITRF product centre to densify the ITRF in the Asia Pacific region. This document overviews the data analysis of APRGP GPS campaign undertaken in 2020.

Mesozoic Alkaline and related igneous rocks of Australia GIS

Alkaline and related rocks are a relatively rare class of igneous rocks worldwide. Alkaline rocks encompass a wide range of rock types and are mineralogically and geochemically diverse. They are typically though to have been derived by generally small to very small degrees of partial melting of a wide range of mantle compositions. As such these rocks have the potential to convey considerable information on the evolution of the Earth’s mantle (asthenosphere and lithosphere), particularly the role of metasomatism which may have been important in their generation or to which such rocks may themselves have contributed. Such rocks, by their unique compositions and or enriched source protoliths, also have considerable metallogenic potential, e.g., diamonds, Th, U, Zr, Hf, Nb, Ta, REEs. It is evident that the geographic occurrences of many of these rock types are also important, and may relate to presence of old cratons, craton margins or major lithospheric breaks. Finally, many alkaline rocks also carry with them mantle xenoliths providing a snapshot of the lithospheric mantle composition at the time of their emplacement.
Accordingly, although Alkaline and related rocks comprise only a volumetrically minor component of the geology of Australia, they are of considerable importance to studies of lithospheric composition, evolution and architecture and to helping constrain the temporal evolution of the lithosphere, as well as more directly to metallogenesis and mineralisation.
This GIS product is part of an ongoing compilation of the distribution and geology of alkaline and related rocks throughout Australia. The accompanying report document alkaline and related rocks of Mesozoic age.

Australian Mineral Exploration: outlook improving but challenges remain

The Australian Bureau of Statistics March quarter data indicate further deterioration in Australian mineral exploration keeping current expenditure levels well below recent levels. Despite this, indicators including increased mineral company floats in 2002 on the back of new discoveries, improved gold prices, increased activity especially by juniors, and prospects for improved metal prices in 2003-2004, present the most positive outlook for mineral exploration since 1997. However, a period of sustained increases in metal prices is required for a significant rise in exploration levels. Exploration is focussed in the Yilgarn Craton, the Tanami Province, the Gawler Craton, the Musgrave Province, and the Murray Basin. The Ashburton province is an emerging gold province and much of the Northern Territory is under tenement for diamonds. Discoveries continue to be made but increased greenfields exploration, especially in areas under cover, is needed to exploit Australia's potential. New government geoscience programs, especially regional pre-competitive geophysical surveys, are playing an important role in helping to unlock that potential.

Delamere, NT, 2015 (P1274), 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 NTGS Delamere and Spirit Hills, NT, 2015 survey were acquired in 2015 by the NT Government, and consisted of 96790 line-kilometres of data at 400m line spacing and 80m 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.

Open source flood simulation with a 2D discontinuous-elevation hydrodynamic model

A new finite volume algorithm to solve the two dimensional shallow water equations on an unstructured triangular mesh has been implemented in the open source ANUGA software, jointly developed by the Australian National University and Geoscience Australia. The algorithm allows for 'discontinuous-elevation', or 'jumps' in the bed profile between neighbouring cells. This has a number of benefits compared with previously implemented 'continuous-elevation'
approaches. Firstly it can preserve stationary states at wet-dry fronts, while also permitting simulation of very shallow frictionally dominated flow down slopes as occurs in direct-rainfall flood models. Additionally the use of discontinuous-elevation enables the sharp resolution of rapid changes in the topography associated with e.g. narrow rectangular drainage channels, or buildings, without the computational expense of a very fine mesh. The approach also supports a simple and computationally efficient treatment of river walls.
A number of benchmark tests are presented illustrating these features of the algorithm, along with its application to urban flood hazard simulation and comparison with field data.

Promotional flyer: The National Geochemical Survey of Australia

The National Geochemical Survey of Australia (NGSA) project was established under the Australian Government's Onshore Energy Security Program (2006-2011). The project is a collaboration between Geoscience Australia and the geological surveys of all States and the Northern Territory. The primary aim of the NGSA project is to provide pre-competitive data and knowledge to support exploration for energy resources in Australia. In particular, it will improve the existing knowledge of the concentrations and distributions of energy-related elements such as uranium (U) and thorium (Th) at the national scale. To date, the project has completed field sampling and sample preparation. Outlet sediments of 1186 large catchments covering &gt;6 M km2 (or 80% of Australia) have been sampled at 2 depths. Sample analyses are under way and will include total, aqua regia digestion and non-selective partial extraction element contents. By June 2011, the NGSA project will deliver a web-based atlas of geochemical maps, a database and a series of reports describing the project and its results. For more information, please visit http://www.ga.gov.au/ngsa or contact Philip Main (philip.main@ga.gov.au)
