Boulia 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Wonthaggi detailed gravity (P198346), 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 Wonthaggi detailed gravity (P198346) contains a total of 327 point data values acquired at a spacing between 500 and 2500 metres. The data is located in VIC and were acquired in 1983, under project No. 198346 for University of Melbourne.

Understanding space weather hazard in the Australian high-voltage power transmission lines using geomagnetic and magnetotelluric data

Geoscience Australia’s geomagnetic observatory network covers one-eighth of the Earth. The first Australian geomagnetic observatory was established in Hobart in 1840. This almost continuous 180-year period of magnetic-field monitoring provides an invaluable dataset for scientific research.
Geomagnetic storms induce electric currents in the Earth that feed into power lines through substation neutral earthing, causing instabilities and sometimes blackouts in electricity transmission systems. Power outages to business, financial and industrial centres cause major disruption and potentially billions of dollars of economic losses. The intensity of geomagnetically induced currents is closely associated with geological structure.
We modelled peak geoelectric field values induced by the 1989 Québec storm for south-eastern Australian states using a scenario analysis. Modelling shows the 3D subsurface geology had a significant impact on the magnitude of induced geoelectric fields, with more than three orders of magnitude difference across conductive basins to resistive cratonic regions in south-eastern Australia. We also estimated geoelectrically induced voltages in the Australian high-voltage power transmission lines by using the scenario analysis results. The geoelectrically induced voltages may exhibit local maxima in the transmission lines at differing times during the course of a magnetic storm depending on the line’s spatial orientation and length with respect to the time-varying inducing field. Real-time forecasting of geomagnetic hazards using Geoscience Australia’s geomagnetic observatory network and magnetotelluric data from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) helps develop national strategies and risk assessment procedures to mitigate space weather hazard.

Lithospheric resistivity model of the Delamerian Orogen from AusLAMP magnetotelluric data

AusLAMP is a collaborative national project to cover Australia with long-period magnetotelluric (MT) data in an approximately 55 km spaced array. Signatures from past tectonothermal events can be retained in the lithosphere for hundreds of millions of years when these events deposit conductive mineralogy that is imaged by MT as electrically conductive pathways. MT also images regions of different bulk conductivity and can help to understand the continuation of crustal domains down into the mantle, and address questions on the tectonic evolution of Australia.
The AusLAMP data presented here were collected as part of three separate collaborative projects involving several organisations. Geoscience Australia (GA), the Geological Survey of South Australia, the Geological Survey of New South Wales, the Geological Survey of Victoria, and the University of Adelaide all contributed staff and/or funding to collection of AusLAMP data; GA and AuScope contributed instrumentation. The data cover the Paleo-Mesoproterozoic Curnamona Province, the Neoproterozoic Flinders Ranges, and the Cambrian Delamerian Orogen, encompassing eastern South Australia and western New South Wales and western Victoria.
This project represents the first electrical resistivity model to image the entire Curnamona Province and most of the onshore extent of the Delamerian Orogen, crossing the geographical state borders between South Australia, New South Wales and Victoria.

Palaeomagnetism and mineral exploration related studies in Australia: a brief overview of Proterozoic applications

Recent improvements to Australian apparent polar wander paths for the different geological periods allow palaeomagnetic analysis to contribute increasingly to reconstruction of mineralisation environments and the study of ore formation processes. This paper looks at the application of palaeomagnetism to the timing of regional chemical alteration, mapping of hydrothermal fluid flow paths, identification and timing of intraplate tectonism (which controls the evolution of sedimentary basins that host mineralisation as well as the circulation of mineralising fluids in the upper crust), location of displaced metallogenic provinces of formerly single tectonic units, and dating of strata.  Numerous examples are available of the application of palaeomagnetism to mineralisation studies, especially in North America. An Australian example is the discovery in the southeastern McArthur Basin of magnetic overprint signatures that suggest wide-spread circulation of fluids during the general period when the HYC Pb-Zn deposit formed. Another Australian example is the dating of the Au-bearing Quamby Conglomerate in the Cloncurry region: the date is substantially older than the earlier, tentatively estimated ages, opening the possibility that the mineralisation occurred within a large fluid circulation system that existed at the time of intrusion of late Palaeoproterozoic granites. Palaeomagnetism has also been used to establish a geological framework that integrates tectonic, magmatic and mineralisation events in northern Australia. A recent palaeomagnetic reconstruction suggests the proximity during the Palaeoproterozoic of the Pacific margins of the Australian and North American cratons, with implications for mineral exploration in both continents.

Australian Mineral Exploration - A Review of Exploration for the Year 2003

Australian mineral exploration spending in 2002-03 rose by 14.4% to $732.5, the first significant increase since 1996-97. 
Global non-ferrous mineral exploration budgets rose 26% to an estimated US$2.4 billion in 2003. Australia's share of reported world budgets was US$339.3 million (15.5%). 
All States and the Northern Territory recorded increases in mineral exploration activity. Western Australia dominated with $423.6 million, 57.8% of total Australian mineral exploration expenditure in 2002-03. 
Gold was the major commodity sought with spending of $378.4 million, 51.7% of the total. There were significant increases in iron ore, coal and nickel exploration. 
Company exploration activities generated a significant number of drill intersections of economic interest, particularly for gold and nickel, in several mineral provinces. A number of junior companies commenced production of nickel and/or have nickel projects at an advanced stage.

Development of the MTPy software package for magnetotelluric data analysis

The MTPy Python library is open source software that aims to facilitate processing, analysis, modelling, and 
inversion of magnetotelluric (MT) data. Until recently, MTpy has contained bugs and gaps in both functionality
and documentation, which have limited its use to date. We are developing MTPy to rectify these problems and 
expand functionality. Key improvements include adding new functions and classes to the modules that handle 
ModEM inputs and outputs, improving data and model visualization tools, refactoring the code to improve 
maintainability, quality, and consistency, and developing documentation.
