Report on Geiger Muller survey, Greenwood's camp area, Mount Painter East

Greenwood's Camp area is situated approximately 1/2 mile east-northeast of the East Painter Camp at the junction of Heighty Creek and an un-named creek along which runs the camel pad to the Mount Painter divide. A reconnaissance survey of the area was made during which a number of small torbernite occurrences were discovered. The area was later mapped in more detail by E. Broadhurst and K. Llewellyn and during the course of their examination the No. 5 prospect was discovered. As a result of his examination Broadhurst recommended that a Geiger-Muller radiation survey should be made of those parts of the area which he considered most likely to contain torbernite or other uranium minerals. The survey under review was carried out as a result of this recommendation. The geology of the area, technical matters, and the results of the survey are discussed in this report.

Regional stratigraphic correlation transects across the Great Artesian Basin - Eromanga and Surat basins focus study

The Australian Government, through the National Water Infrastructure Fund – Expansion, commissioned Geoscience Australia (GA) to undertake the project ‘Assessing the Status of Groundwater in the Great Artesian Basin’ (GAB). The project commenced in July 2019 and will finish in June 2022. The aim of the project is to develop and evaluate new tools and techniques to assess the status of GAB groundwater system to support responsible management of basin water resources. 
A critical relationship exists between sediment depositional architecture and groundwater flow within and between GAB aquifers, and their connectivity with underlying and overlying aquifers. Little is known about lateral and vertical facies variation within the hydrogeological units and potential compartmentalisation and connectivity across the GAB. To improve the understanding of distribution and characteristics of Jurassic and Cretaceous sediments across the Eromanga/Galilee/Surat basins region, GA is compiling, processing and correlating a variety of well log data.
Correlations have been made between geological units of similar age using palynological data from 322 key wells along 28 regional transects to standardise lithostratigraphic units, which are currently described using varying nomenclature, to a single chronostratigraphic chart across the entire GAB. The distribution of generalised sand/shale ratios calculated for 236 wells in the Surat and Eromanga basins are used to estimate the thickness of sand and shale in the different formations, with implications for formation porosity and the hydraulic properties of aquifers and aquitards. This study highlights regional lithological heterogeneity in each hydrogeological unit, and contributes to our understanding of connectivity within and between aquifers.
This report and associated data package provide a first phase of data compilation on 322 key wells in the Surat and Eromanga basins to assist in updating the geological framework for the GAB. A data gap analysis and recommendations for building on this initial work are also provided.

Second report on beryl deposits near Yinnietharra, Western Australia

A brief report on the occurrence of beryl on Yinnietharra Station, Western Australia was prepared following a visit to the locality in December 1948. That report referred to three deposits: 1) 0.25 to 0.5 mile N.25Â°W. from The Cairn; 2)0.25 mile S.60Â°E from the Mica King mine; 3) Rowe's mine, 2 miles southeast from Morrissey Hill. The report stated that 20 or 30 tons of detrital beryl in large pieces could be picked from the surface with ease. It was pointed out that by collecting small pieces and wider search the immediately available tonnage might be doubled. In June 1944, the first two of the above deposits were again visited, as was one on Bidgemia Station not seen on the previous occasion.

National Residential Flood Risk Assessment: A preliminary investigation of Australia’s flood risk

The National Residential Flood Risk Assessment (NRFRA) is a partial response to the need for consistent national risk information, comparable to insurance portfolio analysis information, in the public domain and has been undertaken as a component of the National Climate Risk Assessment (NCRA) Stage Two under the Infrastructure and Built Environment risk category. This work is being led by the Department of Climate Change, Environment, Energy, and Water (DCCEEW) and is drawing upon the expertise from Geoscience Australia (GA) as part of the Australian Climate Service (ACS). The NRFRA is a quantitative evaluation of the likelihood and magnitude of the physical impacts to the built domain within riverine locations arising from flood hazard with a focus on residential separate houses (SH). The NRFRA has provided some insights on relative state level flood risk. It has assessed the flood risk at over 221,000 homes across Australia and communicated the risk at a range of aggregations. The risk outcomes have been translated into a “Vulnerability Index” that can be associated with other socio-economic metrics to give a more holistic and informative view of local scale community flood risk. While the results have been shown to have limitations primarily due to the fidelity of the probabilistic hazard information available, it has provided a demonstration of how consistent flood risk information can be developed nationally. With improved inputs it can provide local scale understanding of present flood risk and with climate influenced flood hazard it can assess future risk. Together these would identify communities exposed to high flood risk now, how this risk will be exacerbated and what communities will become flood-prone in the future. Potentially, it can be further extended to capture changing exposure with future development and the effectiveness of informed land use planning. This would include mitigation strategies to address climate change implications for flood risk and the effectiveness of strategies to progressively address it.

SUPERSEDED - AusArray temporary passive seismic station deployment, servicing and retrieval: Geoscience Australia standard operating procedures

This record has been superseded by eCat 150666. 
The Australian Passive Seismic Array Project (AusArray) program was developed from a long history of passive seismic imaging in Australia involving many contributors. Building on this history, the Australian Government and academia have united around AusArray. The objective is a standardised and quality controlled national passive seismic data coverage and an updatable national seismic velocity model framework that can be used as a background for higher-resolution studies. This document details the field activities and equipment preparation for temporary passive seismic station deployment, service and retrieval. Equipment cleaning and testing and database details are also described. The standard operating procedures applied during these activities were established during the deployment of two temporary passive seismograph arrays under the Australian Government’s Exploring for the Future (EFTF) program. These arrays consisted of 120–130 stations deployed in the Northern Territory and Queensland for over a year in a grid pattern with a lateral spacing of half a degree (~55 km). The temporary passive seismograph stations comprised Nanometrics Trillium Compact 120S broadband seismic sensors connected to a Güralp minimus digitiser. Batteries charged by a solar panel powered both instruments. Each station in the array was serviced, i.e. repairs if required and interim data was retrieved, at least once during the deployment.

Supplies of fluorspar for Australian industry

Attention was directed to the inadequacy of supplies of acid grade fluorspar in Australia when the Bureau of Mineral Resources was asked to sponsor an application to import a quantity from England in 1948. The British Ministry of Supply released a proportion of the amount required but advised that the supply position in England was not secure and only limited quantities could be released for export in the future. The Ministry suggested that if known Australian requirements were likely to be heavy, some material might be supplied as a matter of urgency. An investigation of the fluorspar industry in Australia was then undertaken to estimate future requirements and the extent to which these could be met from domestic sources; the results of this investigation are the subject of this report. The uses, grading, consumption, supply, prices, and projected future supplies of fluorspar are discussed.

Geological report on Kelso and Cleeve stations, Longreach, Queensland

The writer, accompanied by Mr. W.L. Hawthorne of the Geological Survey of Queensland, visited Longreach between 6th to 16th July, 1950, to inspect an area embracing Oakley, Cleeve and Kelso Stations, 8 to 14 miles north-east and east of Longreach. The purpose of the inspection was to re-examine the area previously mapped by Oil Search Ltd., and, if at all feasible, to recommend sites for deep drilling or scout drilling. In all an area of about 18 square miles was examined in sufficient detail to confirm Foster's mapping and to indicate that surface mapping could have little but negative value.  The general geology of the area and previous investigations are described. An account is given of the present field investigation, and its results, together with recommendations for future work.

Report on Consolidated Gold Mines of Coolgardie Ltd (Tindall's gold mine)

The enquiry into this mine resulted from an application by the company for a loan from the Commonwealth to carry out exploration and development. The Tindalls Gold Mine has not been examined by the Bureau and unless this is done no definite statement about the ore possibilities of the property can be made. However, from past reports it seems likely that the deposit has a chance of producing a large tonnage of ore. Under present conditions and with the mining methods now employed, it is extremely doubtful whether ore of this grade could be mined at a profit. The ore reserves, mining, milling, costs, and general financial outlook with respect to the mine are discussed in this report.

Report on 1949 field season - Ord-Victoria region, Northern Australia Regional Survey

The Northern Australian Development Committee nominated the region of the Ord and Victoria rivers to be surveyed by the Northern Australian Regional Survey, when the Barkly Region had been completed. The immediate objectives of the Survey are "to accurately record the nature of the country, to establish a sound basis upon which the production possibilities of the Region may be appraised and to make general recommendations concerning development and further investigations." It was decided that the region should include the Army Four Mile Map Sheets of Delamere, Victoria River Downs, Wave Hill, Birrundudu, Limbunya, Waterloo, Auvergne, Port Keats, Medusa Banks, Cambridge Gulf, Lissadell, Dixon Range, and Gordon Downs, and that the field work would be commenced during the 1949 dry season. The techniques and methods used to complete this survey work are noted. The stratigraphy, pedology, and economic geology of the area are described in some detail.

Report on the salt resources of the Pink Lakes in the county of Weeah, Victoria

This report follows a preliminary report dated 9th September, 1942, and it is not proposed to recapitulate the matter contained therein, although some references to the preliminary report are necessary. The principal purpose of a second visit to the Lakes was to determine accurately the area of useful salt-bearing surface and the nature of the beds. Much evidence confirmatory of the views expressed earlier regarding the structure of the lake beds was noted. However, a plane-table survey revealed that the total extent occupied by recoverable salt is considerably less than a casual inspection would suggest and consists of the following areas, which are shown on the accompanying plan.

Oaklands-Coorabin coalfield - preliminary report

Oaklands is situated about 55 miles north-west of Albury and is about 35 miles from the Murray River. Boring and shaft sinking operations, the results of which are set out in the above reports [see record], have revealed a sequence of sands and clays overlying a coal seam. The maximum proved thickness of sediments is 559 feet, but bedrock has not been reached and the depth thereto is not known. The upper beds of sands and clays are probably Tertiary or younger; the coal seam itself is Permian, but the point of contact between these sediments, though so very different in age, is not known. Aspects concerning the coalfield are discussed in this report including proven coal resources, structure of the field, and economic considerations.

Dalton-Gunning area, New South Wales, earth tremors of March, 1949

On March 11th, 1949, severe earth tremors were felt in the Dalton area, and, less severely, over a considerable portion of New South Wales. These were succeeded in the epicentral area by numerous aftershocks during the following fortnight. G.M. Burton and the writer were detailed to investigate the tremors and left Canberra on the first day of their occurrence. The greater part of the week devoted to the investigation, was spent in the Dalton area. A reconnaissance embracing an area within a radius of some 40 miles of Dalton was also carried out with a view to determining the regional distribution of intensities, and the Chief Geologist circularised Post Masters and Police Officers stationed at fourteen N.S.W. towns from which some information about the tremors was to be expected. This report provides a general description of the earth tremors and their effects. Instrumental data readings are recorded. The geology and physiography of the area, and their relation to the position of the epicentral area, as well as the causes of the tremors, are discussed. Plans showing the distribution, on a modified Mercalli scale, of seismic intensities during the earth tremors are included.

Notes on the Upper Yarraman bentonite deposit, Queensland

This deposit was examined in company with Mr. L.C. Ball, Chief Government Geologist of the Queensland Geological Survey on Wednesday, January 5th, 1944. It has previously been described in some detail by H.G.S. Cribb of the Geological Survey. Since Mr. Cribb's examination was made, the workings southwesterly from the shaft have been extended somewhat, but the owners, Messrs. Elver Bros., at the time of our visit were proposing to abandon that shaft on account of water and the fact that the drives were too long for economic working. The mining method used is expensive, slow and inefficient. Less than 50%, probably only about 30% of the bentonite is recovered by the existing procedure.
This report details the origin of the deposits and proposals for future testing.

Geological report on a site for a brick pit at Deakin

At least as early as 1940, it was realised by the Department of the Interior that the reserves of suitable rock (shale or slate) in the pit adjacent to the Canberra Brickworks were limited. A decision was made to find a temporary site to provide sufficient material to supply the brickworks for two years. A site at Deakin, 1700 yards by road east from the existing brickworks was selected and was recommended by Dr. W.G. Woolnough in 1940 as suitable, subject to testing by costeans and pits. A survey of the area in the subdivision of Deakin, Canberra City Area, was then arranged and was made during March and April, 1944, the object being to determine if there were sufficient reserves of suitable material to supply the Canberra brickworks for a period of not less than two years. This report describes the results of this survey.
