Micropalaeontological examination of two samples from the Joint Coal Board Bore, Camberwell, near Singleton, New South Wales

The two samples submitted for micropalaeontological examination, came from the depths of 290 feet and 320 feet respectively. They consisted of hard, grey, carbonaceous shale. Crushings of the rocks yielded a small assemblage of arenaceous foraminifera and pyritic casts of ostracoda of Permian age. A list of the forms in each sample is as follows.

Cambrian stratigraphy of the Camooweal region: (progress report)

The 1953 field reports refer to several rock units of the Cambrian sequences of the Undilla Basin without defining the units. These units were established in previous years, but all the records and prepared reports were destroyed in the autumn of 1953. The author used this nomenclature in his field reports on the assumption that it would be known to prospective readers. In the present report the definitions are given in a brief and preliminary form. The field maps show the distribution of the rock units, but, as the field reports contain no explanatory sections, these are presented here. The study of the collections included the examination of the lithology and definition and determination of the vertical distribution of fossils. The results of the lithological examination will be given later. The vertical distribution of genera and species of fossils, however, shows the existence of a sequence of biozones (species-zones); it indicates the presence of four fossil stages in the Middle Cambrian sequence and is presented in Chart 2. The fossil list is incomplete, and the nomenclature applied is not final.

Fossiliferous rocks from the Nullabor Plains

In 1944, while Mr. H. B. Owen, geologist of the Bureau of Mineral Resources, was travelling by road from Port Lincoln, South Australia, to Norseman, Western Australia, he collected specimens of the Tertiary rocks for micropalaeontological examination. A detailed report on these samples has never been put on record, but, as the area is now being investigated for the possibility of oil accumulation, the samples have been examined and this report prepared. Some interesting observations made by Mr. Owen during the trip are incorporated here. The most important results of the micropalaeontological examination of these limestones are: 1. The discovery of extensive deposits of upper Eocene age both in outcrop and in subsurface sections; 2. The similarity of the upper Eocene to lower Miocene stratigraphical sequence in the coastal area of the Nullarbor Plains with that found in portion[s] of the Carnarvon Basin, Western Australia, in the Adelaide Basin, South Australia, in north-western Victoria, and in the Torquay area, central southern Victoria.

Geophysical investigations of water deposits, Western Australia

With Australia's postwar immigration programme and the increased demand for food supplies, an expansion of Australia's rural industries is of primary importance, both to increase domestic food supplies and to obtain foreign exchange by export of primary produce. For such a development, the rainfall, surface and underground water resources are the factors of prime importance. In West Australia the difficulties met in finding water for farming purposes prevents rational development of many rural areas. Also, in some places town water supplies are insufficient or the water is saline. Water resources may be classified as follow: rain water from tanks or dams, water from bores or wells, water from old mine shafts (in mining districts), water from springs, [and] water from rivers. The present investigations are not concerned with the last two types of water supply. The following aims were set. 1. To test several types of instruments, to discover their limitations and ranges and the optimum conditions for their operations. 2. To estimate the accuracy of depth determination to discontinuities which might be related to the geology. 3. To investigate the possibility of distinguishing the nature of the discontinuities, for instance, decomposed granite, fresh granite, ground water level, etc., and the possibility of estimating whether ground water is fresh, brackish or saline. The tests areas were selected in the belief that sufficient bore information would be available to serve as controls. However, except at Austin Downs, near Cue, and at Big Bell, the bore information was generally insufficient, vague and unreliable. With the exceptions mentioned above, adequate records had not been kept. The purpose of the geophysical survey was not primarily to search for areas with favourable ground water occurrences but to test the resistivity method in areas where information on the occurrence of ground water was available from existing wells and bores. The order in which the tests are described in the report is: Wubin, Cue, Big Bell, Lake Grace and Kulkin.

Preliminary report on seismic reflection survey, Avon area, Gippsland, Victoria

Gravity surveys were conducted of the Gippsland Lakes district during 1949 and 1951. Both surveys showed an anomaly immediately to the north of Lake Wellington, the magnetic anomaly being a little displaced to the north-west of the gravity anomaly. The size and nature of the magnetic anomaly suggested that it might be due to rocks with higher than normal magnetic susceptibility in the basement complex. The gravity anomaly might be due to a buried hill in the Jurassic or basement, perhaps associated with the same feature which is responsible for the magnetic anomaly. Such a buried hill could result in a geological structure favourable to the accumulation of oil being present in the overlying Tertiary rocks, and in order to test whether or not a favourable structure existed a seismic reflection survey was undertaken by the Bureau. This report deals with the results of the seismic survey. Two north-south traverses and one running east-west and crossing the other two were surveyed.

Summary statement of Australian bauxite reserves at 31st December, 1952

This statement has been prepared as a supplement to Summary Report No. 27 - Aluminium and Bauxite - which was issued in 1946. Since that year testing of deposits in Tasmania has been completed and new discoveries of commercial bauxite have been made in northern New South Wales and the Northern Territory. Further exploration in South Gippsland has resulted in minor additions to the proved reserves of Victoria, and the presence of bauxite has been reported in Papua and New Guinea. Exploration of deposits of bauxite on the north coast of the Northern Territory is not complete but sufficient accessible reserves have been proved to change the formerly unfavourable outlook for the aluminium industry now being established in Australia. Re-examination of the formerly known deposits has necessitated recalculation of the stated reserves, and has generally resulted in a reduction of the earlier estimates, but, on the other hand, a substantial increase has been made for the Tamborine Mountain deposits in Queensland. South Gippsland tonnages have been recalculated and expressed as dry ore for the sake of greater accuracy and consistency. Tonnages throughout are long tons (2240 pounds) of dry ore. In the following tables proved reserves are those which have been systematically tested by pits or bores regularly spaced at intervals of not more than 400 feet, and in many cases only 100 feet. Indicated reserves have been tested by more widely or irregularly spaced holes.

Investing in free and ready access to groundwater knowledge for all Australians through the National Hydrogeological Inventory

Geoscience Australia is investing in improved access to groundwater data to support informed water management decision-making for the benefit of all Australians. In 2023, we released the National Hydrogeological Inventory (NHI) to provide a nation-wide overview of Australia’s major hydrogeological provinces. The initial release of the NHI, accessible via our online Data Delivery Portal, provides access to a wealth of data and summary information about the hydrogeology and groundwater systems of the nation’s 42 major hydrogeological provinces. This content is further enhanced by valuable contextual information about the people, communities, industries, and environmental assets that rely on groundwater within these provinces.

Complementing the national-scale overview were two regional hydrogeological investigations of trans-jurisdictional aquifers of the Kati Thanda - Lake Eyre Basin in central Australia, and the South Nicholson - Georgina Basin in northern Australia. These in-depth studies included new data analysis and integration of hydrogeological, hydrochemical, geophysical and other datasets to develop improved conceptual understanding of groundwater flow systems and related processes and interactions.

Under the recently announced Resourcing Australia's Prosperity Initiative, Geoscience Australia is embarking on the next phase of development to improve the NHI. Novel updates and modifications currently planned include: 1. Enhanced visualisations via the portal interface; 2. Addition of new data and narrative content for province reports; and 3. Further detailed hydrogeological studies in priority regions.

As we continue to grow the NHI and its long-term vision as a national compendium of hydrogeological knowledge, we welcome input and ideas from the Australian and international hydrogeological communities.

Presented at the 52nd Congress of International Association of Hydrogeologists (IAH2025)

Timor Sea Biozonation and Stratigraphy Chart No. 5

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

Uranium prospects, Waterhouse area, Northern Territory: (preliminary report & maps)

The area described in this report extends for 6.5 miles south of the southern boundary of the Hundred of Goyder, and for approximately 8.5 miles west of the Stuart Highway. The North Australian Railway runs approximately through the centre of the area. No uranium-bearing minerals have yet been discovered in the Waterhouse Area, but copper mineralization, associated with some radioactivity is known to occur. A slate formation, which is partly graphic, carries the main signs of copper and uranium mineralization noted to date, and is underlain by a quartzite breccia. Those beds are similar to, and are possibly identical with, those carrying the uranium and copper ore at Rum Jungle, where surface showings were not impressive. The mineralized slate at Waterhouse warrants prospecting and at least one known deposit warrants drilling. Other parts of the area, in which radiometric anomalies have been found by the airborne scintillometer, need further ground investigation.

A further collection of limestones from Rough Range structure, Carnarvon Basin, Western Australia

Twelve rock samples from the Rough Range Structure were submitted by West Australian Petroleum Pty. Ltd. for micropalaeontological examination.  The result of the examination of an earlier collection was given in Records 1955/48.  Seven of the present samples came from a gully due east of Rough Range Well No.6 and five from a gully due east of Rough Range Well No.6 and five from a gully immediately south of Rough Range Well No.7.  The distance between the two well sites is approximately 2 Â¼ miles.  A detailed description of samples from each section together with the thickness of the section is given below.  The sections from each locality are arranged in descending stratigraphical sequence.

Geophysical survey at Mount Cleveland mine, Waratah, Tasmania

Self-potential and magnetic surveys made in the vicinity of the Mount Cleveland Tin Mine, near Waratah, Tasmania, are described and discussed. The first survey, which is described in Part I of this report, was made in April and May, 1953, at the request of the Department of Mines, Tasmania. The object of the survey was to ascertain whether geophysical methods could detect the known area of mineralisation and, if so, whether any additional areas of mineralisation could be discovered. Results of the first survey show that the geophysical anomalies, particularly the self-potential ones, coincide with the old mine workings. The anomalies over Luck's and Hall's workings, however, cover larger areas than the actual mine workings, thus indicating that further sulphide mineralisation may exist beyond these old workings. Anomalies not related to the old workings appear in an area north-west of Deep Creek, between traverses O and R. Both self-potential and magnetic methods revealed anomalies along these traverses between 350.E and 650.E, where geological investigation has also shown mineralisation to exist. Based on the results of the first survey, the grid was extended and surveyed to the north-east and south-west in March and April, 1954. This second survey, which is described in Part 2 of the report, shows that the anomaly connected with Henry's workings does not extend to the north-east, but terminates sharply between traverses P and Q. Some additional anomalies were recorded in the north-eastern extension of the grid, but in the south-western extension there was no geophysical evidence of mineralisation. It is suggested that further mining exploration work should be concentrated mainly near the former mine workings and in the area to the north-west of Deep Creek, between traverses O and R. Some prospecting trenches should also be put down to test the minor anomalies in the north-eastern part of the area.

Magnetic survey of compass swinging site, R.A.A.F. airfield, Laverton, Victoria

A declinometer survey was made over three sites at the R.A.A.F. Airfield at Laverton, Victoria, in January 1952, to determine their suitability as compass-swinging bases. The results show that at all three sites there are local magnetic disturbances which cause deviations in excess of the permissible maximum of one quarter of a degree. None of the sites is suitable.

L095 Braidwood Tidbinbilla deep crustal seismic reflection survey (Murrumbidgee Batholith Basin), ACT, NSW, 1969 Stacked seismic data and images for line BMR69-BA

An experimental seismic reflection survey was made at Tidbinbilla, ACT and Braidwood, NSW in 1969 to investigate the use of long spreads and common-depth-point profiling techniques for recording deep crustal reflections. The survey was complementary to an experimental seismic survey at Mildura, Victoria and Broken Hill, NSW in 1968 to develop techniques for recording deep crustal reflections preparatory to a seismic reflection survey on the 'Geotraverse', a line across the Precambrian shield in the southern part of Western Australia, along which the Australian Upper Mantel Committee initiated a project to study the Earth's crust and upper mantle.
