AUSGeoid98 v.1.0 data files: (sf49-01)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

National Geochemical Survey of Australia: Field Data

From 2007 to 2009, the National Geochemical Survey of Australia (NGSA) project collected sediment samples from 1315 sites located in 1186 catchments (~10 % of which were sampled in duplicate) from across Australia.
Overbank sediments were chosen as sampling media, with a near-surface sample (Top Outlet Sediment, TOS, from 0-10 cm below the surface) and a bottom sample (Bottom Outlet Sediment, BOS, ~10 cm interval between approximately 60-80 cm below the surface) being collected. The sample sites were selected to be near outlets or spill points of large catchments, so that overbank sediments there could reasonably be assumed to represent well-mixed, fine-grained composite samples of all major rock and soil types present in the catchment. 
Sample sites and their corresponding sediment samples were subjected to a detailed description and the determination of bulk parameters in the field (texture, moist and dry colour, field pH). This is complemented by a series of laboratory measurements and analyses reported elsewhere. 
This report documents the complete field dataset and discusses the pH and soil colour data that were collected in the field. At the time of writing, field pH and colour are the only datasets available for all sites. Maps are presented showing the spatial distribution of these data in both TOS and BOS samples. These data will be the basis of further interpretative work.

Forensic PSHA: Benchmarking Canada’s 5th Generation Seismic Hazard Model using the OpenQuake-engine

This paper explores the implementation of the Natural Resources Canada’s 5th Generation national seismic hazard model as developed for the National Building Code of Canada (NBCC), within the OpenQuake-engine. It also describes the reconciliation of the differences in hazard estimates relative to the published NBCC values, calculated using GSCFRISK. Source and ground-motion input models developed for the GSCFRISK software were translated to the OpenQuake-engine format for the hazard comparison. In order to successfully undertake this process, several adjustments to the OpenQuake code were needed to mimic the behavior of GSCFRISK. This required the development of new functions for earthquake rupture scaling and ground-motion interpolation. Hazard values estimated using the OpenQuake-engine are generally in good agreement with the 2015 NBCC national-scale hazard values, with differences less than 2-3% typically achieved. Where larger differences arise, they can be rationalized in terms of differences between the behaviours of the two software engines with respect to earthquake rupture length uncertainty and maximum ground-motion integration distance.

Review of the Proterozoic geology and mineral potential of the Curnamona Province in South Australia

The Proterozoic Curnamona Province extends across northeastern South Australia and western New South Wales, with exposures in the Willyama, Mount Painter and Mount Babbage Inliers, but much of it is obscured by younger sedimentary cover. Curnamona Province rocks comprise a late Palaeoproterozoic metasedimentary and metavolcanic succession (Willyama Supergroup) with some meta-intrusives and early Mesoproterozoic volcanics, sediments and granitoid intrusives. The Willyama Supergroup in South Australia is divided into the Olary and Broken Hill Domains on the basis of lithological and geophysical character, with a strong linear magnetic feature marking the boundary. A tentative lithostratigraphy has been established for the Olary Domain, in parallel with the Broken Hill Domain. Limited geochronology indicates broad contemporaneity, but the Olary Domain differs in the apparent dominance of shallow-water or evaporitic sediments, the relative paucity of volcanics, the presence of widespread metasomatism, particularly albitisation and associated brecciation, and abundant Mesoproterozoic granitoids.  Current mapping of the Broken Hill Domain in South Australia has identified lithologies comparable with the Thorndale Composite Gneiss, Thackaringa Group, Broken Hill Group and Sundown Group.  The Benagerie Ridge, known only from limited drilling, contains lower metamorphic grade metasediments consistent with the northwards decrease of grade observed in the Olary Domain. Further north on the ridge, essentially flat-lying Mesoproterozoic sediments and acid and basic volcanics may overlie Willyama Supergroup.  The Willyama Inliers in South Australia have widespread base-metal, gold and uranium occurrences, although total production has been very small, except for the Radium Hill uranium mine. In the Broken Hill Domain, known mineralisation includes a copper sulphide resource at the Mutooroo Mine and several large, low-grade bodies of disseminated copper and zinc sulphides. The Olary Domain has numerous occurrences of copper, zinc, lead and gold associated with sulphidic, calc-silicate and albitic units. Copper and gold are also associated with stratabound quartz- magnetite bodies lower in the sequence. Discordant, epigenetic, base metal- and gold-bearing veins are also widespread in the Willyama Supergroup, related particularly to the retrogressive phase of the Mesoproterozoic Olarian Orogeny and to the Cambro-Ordovician Delamerian Orogeny. Significant intersections of copper, zinc, molybdenum and gold mineralisation have been found in ?Willyama Supergroup metasediments in the southern Benagerie Ridge. In general, the Curnamona Province is prospective for stratiform and stratabound lead- zinc and Olympic Dam and Cloncurry Belt style copper- gold(- uranium) mineralisation.

L011 Darriman seismic reflection survey, VIC, 1954

The seismic reflection survey was carried out in the Parish of Darriman, Victoria. The survey was planned to investigate a gravity anomaly, which may be an indication of a structure within the sedimentary section favourable to the accumulation of oil or natural gas. For the most part reflections were exceptionally good, and it was possible to trace one reflecting layer over most of the area. Contouring showed the presence of an
anticlinal structure, plunging to the east, but rising and broadening to the west. On the flat crest of the  tructure, there is probable closure in two places. The thickness of the Tertiary sediments may be a maximum of 6,000 feet, but may be only 3,000 feet on the crest of the structure and 4,000 feet on the flanks.

Precambrian metamorphism, fluid flow, and metallogeny of Australia

Current models for metamorphic fluid flow provide a framework for understanding the setting and genesis of Australian Precambrian ore deposits thought to have formed during metamorphism.  Ideal conditions for formation of large metamorphogenic ores are a) an initial phase of metals dissolution by penetrative flow of devolatilisation, surface or igneous fluids along pathways of constant or increasing temperature, because channelised fluid flow will not normally provide the required metal volumes or transport continuity to subsequently form large ore deposits, and b) a subsequent phase of channelised fluid flow, particularly during retrogression or fluid mixing where temperature or fluid chemical changes combine with rapid fluctuations in fluid pressure accompanying dilatancy pumping. Protracted thermal histories and the identification of multiple hydrothermal events in major mineralised blocks (Yilgarn, Mt Isa, Broken Hill) provide some weight for multi-stage ore enesis models, particularly for giant ore deposits. Despite continuing uncertainty about the tectonic setting of many major mineral provinces, intra-plate orogeny, particularly in the Palaeoproterozoic and Mesoproterozoic, appears to provide the necessary conditions for development of rich mineral provinces. Such orogenies have the right combinations of temperature- pressure history, fluid evolution and magma generation to provide optimum conditions for ore genesis. A common feature to intracratonic belts of this age is an early phase of crustal extension following or synchronous with mafic magma underplating, and this early underplating may be the ultimate reason for primary metals enrichment. However, the subsequent path history of metals culminating in ore deposition is still controversial and poorly understood for most Australia Precambrian terrains.

A U–Pb geochronology compilation for northern Australia

This record presents a data compilation and thematic maps for existing U–Pb age data for a range of methods and minerals for an area of northern Australia. The compilation includes 2240 age results from the Northern Territory, Queensland and selected areas of South Australia, Western Australia and New South Wales. U–Pb age data was sourced from Geoscience Australia, the Northern Territory Geological Survey, the Geological Survey of Queensland, the Geological Survey of Western Australia and the published scientific literature. 
Thematic maps have been created from the compiled dataset and show the spatial distribution and age trends of igneous crystallisation ages, maximum depositional ages and metamorphic ages across northern Australia. This work can be used as both a standalone dataset and in conjunction with other geological, geochemical, isotopic and geophysical datasets to better understand the geological evolution of northern Australia.

Australia's Identified Mineral Resources 2007

Geoscience Australia provides information on the nation's future capacity to produce mineral resources. Australia's Identified Mineral Resources is an annual nation-wide assessment of Australia's ore reserves and mineral resources. All major and a number of minor mineral commodities mined in Australia are assessed. It includes international rankings, summaries of significant exploration results, brief reviews of mining industry developments, and an analysis of mineral exploration expenditure across the States and Northern Territory. AIMR provides governments, industry, the investment sector and general community with an informed understanding of Australia's known mineral endowment and level of exploration activity. An important objective is to monitor whether resources are being discovered and developed for production at rates sufficient to maintain Australia's position as a major supplier of mineral commodities.
Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2006Â - black coal, copper, gold, iron ore, rutile, zircon, platinum group metals, silver, tin, tungsten and vanadium. EDR of bauxite, cobalt, diamond (gem and industrial), lead, manganese, nickel, uranium and zinc decreased in the same period. EDR for brown coal, magnesite, molybdenum, niobium, shale oil and tantalum remained at levels similar to those reported in 2005. Estimates of Australia's resources of coal bed methane gas are reported for the first time in AIMR.
Increases in EDR were due to on-going drilling and evaluation of known deposits resulting in the transfer (re-assessment) of resources from inferred or sub-economic categories into EDR, and discoveries of new deposits or extensions of known deposits. Sustained increases in prices for most metal and mineral commodities over recent years has allowed companies re-assess the economic viability of lower grade resources and deposits which were previously considered to be uneconomic. Overall this has contributed to an increase in EDR for many metal and mineral commodities.

Colac Traverse Vic (P199232), 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 Colac Traverse Vic (P199232) contains a total of 98 point data values acquired at a spacing of 200 metres. The data is located in VIC and were acquired in 1992, under project No. 199232 for None.
