Deposits of lithium-bearing minerals in Australia

The following summary of deposits of lithium-bearing minerals in Australia has been compiled from office records, including the previous statement on amblygonite deposits by P.B. Nye, and reports on Western Australian deposits by H.A. Ellis of the Geological Survey of the State. Much of the information on the Northern Territory deposits has been obtained from an article by A.E. Williams in 'Chemical Engineering and Mining Review' of July, 1940. A discussion of Australian sources by State and Territory follows in the report. A summary of Australian amblygonite production figures for 1905 to 1943 is included.

Mineral exploration in Australia: paper for fourth Empire Mining and Metallurgical Congress

The scientific search for ore in Australia is still in an early stage of development, because, until recently, a sufficient supply of metals was available from concentrations readily detectable by ordinary prospecting methods. Now the whole mineral supply position is changing and the rate of discovery of new deposits by prospectors in the present century had been quite discouraging. The Australian Government and the Australian mineral industry have recognised the need for mineral exploration both to supply home requirements and to assist in overcoming world shortages. An overview of the situation is presented in this report, which outlines the problem and the corrective reforms and activities undertaken by the state and federal governments, and mining companies, to promote mineral exploration. A summary is given of the exploration and ore-finding work undertaken by mining companies and government agencies between 1930 and 1949.

Mesoproterozoic basins of Australia

The preserved successions from the Mesoproterozoic Era (1600 to 1000 Ma) are a relatively understudied part of Australian geological evolution, especially considering that this era has a greater time span than the entire Phanerozoic. These rocks are mostly known in variably-preserved sedimentary basins overlying Paleoproterozoic or Archean cratons or at the margins of these cratons. Some metamorphosed equivalents occur within the orogens between or marginal to these cratons.
Both energy and mineral resources are hosted in Australian Mesoproterozoic basins, including the highly-prospective organic rich shale units within the Beetaloo Sub-basin (Northern Territory), which form part of the Beetaloo Petroleum Supersystem. The primary aim for this record is to provide a consolidated state of knowledge of Australian basins or successions similar in age to that of the Mesoproterozoic Beetaloo Petroleum Supersystem. The findings of this report will assist prioritising future work, through improved geological understanding and resource prospectivity.
This report presents an overview of 14 Mesoproterozoic-age sedimentary basins or successions and their current level of understanding, including location, basin architecture, stratigraphy and depositional environments, age constraints and mineral and energy resources. Basins or successions included in this record are unmetamorphosed or metamorphosed to very low-grade conditions.
Recommendations are made for future work to address the main knowledge gaps identified from this review. While some of these basins have been the focus of recent intense study and data acquisition, the extent of knowledge varies broadly across basins. All basins reviewed in this record would benefit from further geochemical and geochronological analyses, and stratigraphic study to better understand the timing of depositional events and their correlation with nearby basins. Elucidation of the post-depositional history of alteration, migration of fluids and/or hydrocarbons would facilitate future exploration and resource evaluation.

Preliminary report on the examination of cores from the Pilot bore, Lakes Entrance, Victoria

The Pilot Bore is situated 130 feet north of the Lakes Entrance Shaft and 80 feet above mean tide level. The principal purpose of the bore was to provide information on the position and flow of aquifers and on the nature of the rock ahead of shaft sinking operations. Percussion drilling was used to ensure that information on water horizons should be as accurate as possible. This report summarises the information so far obtained from the Pilot Bore, Lakes Entrance, and should be regarded as an interim statement pending the completion of work on the cores. The task of correlating this information with that obtained from other sources and the discussion of its bearing on regional problems are reserved for a more detailed report when the work has been concluded.

Exploring for the Future – whole rock inorganic geochemistry of sedimentary rocks from Barnicarndy 1, Canning Basin, Western Australia

Exploring for the Future (EFTF) is an Australian Government program led by Geoscience Australia, in partnership with state and Northern Territory governments. This first phase of the EFTF program (2016–2020) aimed to assist industry investment in resource exploration in frontier regions of northern Australia by providing precompetitive data and information about energy, mineral and groundwater resource potential. As part of this initiative, this record presents whole-rock inorganic geochemistry data including X-ray fluorescence (XRF) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses and quantitative X-ray diffraction (qXRD) results for 67 drill core and cuttings samples of sedimentary rocks from Barnicarndy 1 drilled in the Barnicarndy Graben of the Canning Basin. The inorganic geochemistry analyses were undertaken by Geoscience Australia and Bureau Veritas (BV). This work complements other components of the EFTF program, including a comprehensive sampling program of the Barnicarndy 1 deep stratigraphic well, the Kidson Sub-basin seismic survey, and the Kidson Sub-basin petroleum systems model to better understand the geological evolution, basin architecture and petroleum prospectivity of the region.

The discovery of scheelite deposits at Yetholme, New South Wales

The occurrence of molybdenite deposits near Yetholme has been known for many years. The most important deposits are close to the eastern boundary of Ph. Yetholme, Co. Roxburgh. The deposits have been worked in a small way for molybdenite at several places, have been examined by several geologists, and have been investigated by two of the major mining companies. The result of this work has shown that although considerable tonnages are available, the molybdenite content is too low to make mining attractive. It is not proposed to describe the geology, mining excavations, and other factors affecting the field in this report since that has already been done in several previous reports. It is the purpose of this report, however, to point out that the Yetholme deposits contain a considerable amount of scheelite and may well warrant large scale mining for this now important ore of tungsten.

Organic petrography of Proterozoic shales from northern Australia

The Exploring for the Future program is an initiative by the Australian Government dedicated to boosting investment in resource exploration in Australia. As part of the Exploring for the Future program, this study aims to improve our understanding of the petroleum resource potential of northern Australia. 
The physical properties of organic matter in sedimentary rocks changes composition in an irreversible and often sequential manner after burial, diagenesis, catagenesis and metagenesis with increasing thermal maturity. Characterising these changes and identifying the thermal maturity of sedimentary rocks is essential for calculating thermal models needed in a petroleum systems analysis.
This study presents organic petrology on 15 Proterozoic aged shales from the Velkerri and Barney Creek formations in the McArthur Basin and the Mullera Formation, Riversleigh Siltstone, Lawn Hill and Termite Range formations in the South Nicholson region. Qualitative maceral analysis of the 15 samples are described in addition to bitumen reflectance measurements. These samples were analysed at the Montanuniversität Leoben, Austria in June 2020.
The results of this study can be used to improve our understanding of the thermal maturity and hydrocarbon prospectivity of Proterozoic aged sedimentary basins in northern Australia.

Interim report on Nelson Bore, Victoria

The Nelson Bore, which is still in progress and is being drilled with the Commonwealth Rotary plant in collaboration with the Victorian Mines Department, has now reached the depth of 3746 feet, with no indication that the basement rock will soon be reached. Unfortunately no bore in Western Victoria or south-eastern South Australia has been drilled to bedrock, consequently no suggestion can be made as to the possible depth at which it will be met in the present bore. The deepest bore in the area to be palaeontologically examined is Knight's Dome, No. 2, Mt. Gambier, South Australia, which reached the depth of 2013 feet, drilling ceasing in carbonaceous sands.

Merton's clay deposit, Parish of Queanbeyan

During an inspection of limestone deposits at White Rocks on 2/11/50, samples of weathered granite were collected from a quarry on the eastern side of the Queanbeyan-Cooma road, about 150 yards south of the two-mile peg. This quarry is in the Queanbeyan Clay Deposit described by W.G. Woolnough in departmental reports dated 17/2/28 and 20/6/28. If the rock can be economically crushed and worked, it may be suitable for the production of sewer-pipes and other impervious ware. The samples, reserves, and suitable uses for the granite are described in this report.

Report on the geology of the Kowen district, Australian Capital Territory

The Kowan District occupies the north-eastern lobe of the A.C.T., to the north-east of Queanbeyan. The purpose of the survey was to determine the general geology and structure of the Kowen District as part of a planned mapping of the whole of the A.C.T. In addition a search was made for commercial occurrences of rock suitable for use as a building stone. Field work was extended over most of January and February, 1949. Igneous intrusions were plotted directly onto aerial photographs where possible. Strikes of beds and faults and other suitable information were measured by prismatic compass and dips and pitches were measured by Abney level or clinometer compass. Information was then plotted on a Federal Territory feature map. A full account of this survey work and its findings is given in this report. Descriptions of specimens and geological plans of the district are appended.
