Report on inspection of portion of proposed authority to prospect No. 151 (Sleisbeck), Northern Territory

The following report concerns the geology and mineralization of two uranium prospects in the Gimbat - Snake Creek Area of the Northern Territory. One of these prospects, referred to as Sleisbeck, can be recognised as one of the most favourable yet discovered in the Northern Territory. The radioactivity occurs in a quartzite breccia outcropping over a length of 1.5 miles and with a width of as much as several hundred feet. Geiger counter readings of 2 - 100 times background, occur frequently along the entire length of the outcrop, visible mineralization being present at three separate localities. The state of this mineralization, its associations and the geological settings are favourable to the possible occurrence of uranium mineralization at depth. Recommendations are made for further work, and problems in regional geology are discussed. The writer considers the sections of this report designated "Mineralization" and "Conclusions" to be the most important for a knowledge of the actual uranium occurrences. The remaining information is mainly geological, and, while highly pertinent, may not be of urgent interest to readers with a limited amount of time.

Micropalaeontology of the Pliocene deposits at Portland, Western Victoria

During a recent visit to Portland with Dr. N. Boutakoff and Mr. Spencer Jones of the Geological Survey of Victoria, samples were collected systematically at localities along Dutton Way which skirts the eastern shores of Portland Bay and along the foreshore below the station.  Locality 2 on Dutton Way represents the type of Maritemo Formation and is approximately eight feet thick.  These beds overlie the white deposits of the Portland Limestone and are overlain by basalt.  The monument section shows portion of the Maritemo Beds and portion of the topmost unit of the Formation, the Werriko Beds.  This section is also overlain by basalt and underlain by Portland Limestone.

An examination of thermal areas, Vitu (Garove) Island, August 26-27th, 1954

No details are available of the previous volcanic activity of Vitu Island, but some old natives have stories of unusual phenomena referable to vulcanism which accompanied a change in sea level many years ago. The inference of the stories was that the change was sudden and accompanied by increased emissions of steam from Zones A and B (of this report). It was impossible to assess from natives interrogated how long ago this occurred, but palms estimated to be about 40 years old grow near the shore in the area to which the stories refer. This area embraces the Catholic Mission, Balangori No. 2 village and Mt. Utopi, and, according to legend, most of the coastal portion to an height of about 300 feet was previously submerged. A more detailed survey of the island would be necessary to establish the veracity of the stories, but there is certainly evidence that portion of the area was submerged. Old oyster shells occur to heights of about 30 feet above sea level attached to basalt cliffs below the Catholic Mission. Since it was necessary for the "Theresa May", on which the writer was travelling, to visit the Vitu Island Group on the return trip from the Langila Crater investigation, the advantage was taken of examining as many thermal areas as possible. Although geysers and fumaroles occur on Narage Island, the northernmost island of the group, it was possible only to examine briefly those areas on Vitu (Garove) Island in the time available.

The geological significance of the discovery of oil at Rough Range, Western Australia

On 4th December, 1953 the discovery of oil in West Australian Petroleum Company's first exploration bore, Rough Range, No. 1, was announced. It was stated that the tested flow was 500 barrels a day. This is the first significant flow of oil in Australia, although small flows of oil and some flows of gas have occurred in other parts of the continent. Despite the fact that this is the first exploration bore for oil in this basin, the stratigraphy and structure of the basin is moderately well established. The main new fact that has so far come out of this bore is the indubitable presence of oil in a basin where no seepage or other direct sign of petroleum has been found. The following short statement of the stratigraphy, structure and palaeogeography of the Carnarvon Basin as at present known will indicate the geological background on which the West Australian Petroleum Company decided to test.

Dyson's Find (1951), Rum Jungle N.T.

Dyson's Find is situated 1000 yards east-north-east of White's workings. A radiometric anomaly was discovered here in 1950 by geophysicist D.F. Dyson while traversing the sedimentary rocks between Giant's Reef to the south and the edge of Rum Jungle to the north. No uranium minerals were visible on the surface but costeaning revealed four lines of strong secondary uranium mineralisation. In 1950 the area was mapped by H.J. Ward on a scale of 50 feet to one inch. A prospecting shaft (No. 1 Shaft) was sunk to a depth of 54 feet on one of the uraniferous lodes and some costeaning carried out. In 1951 further mapping on a scale of 20 feet to one inch was done by the writer. Diamond drilling was carried out and a new shaft (No. 2) was sunk to 84 feet. A plan showing the surface geology and working and a section along coordinate N170 accompanies this report. [Geology, structure, mineralization, workings, diamond drilling, ore reserves, and prospecting recommendations are discussed].

Radioactive surveying from a helicopter (abridged version)

In connection with the use of airborne equipment for the detection of deposits of radio-active minerals, the Bureau has successfully used a DC.3 aircraft for the rapid coverage of large areas. It has been frequently suggested that a helicopter would have the following advantages over a conventional aircraft: (i) It can fly safely at lower heights and slower speeds than an ordinary aircraft, thus obtaining greater sensitivity from the detecting apparatus; (ii) It can be used effectively and safely in mountainous areas, in which low flying by a conventional aircraft would be impossible; (iii) It would enable the observer to locate exactly and identify from the air any small area on the ground showing radio-activity. In order to assess the performance of helicopters, a programme of test helicopter-mounted equipment over selected areas in New South Wales was carried out during March, 1953. The areas selected were: (i) Carcoar. This is a hilly area, but not timbered; (ii) Wunglebung, near Tenterfield. This is a mountainous, heavily timbered area; (iii) Broken Hill. This is a relatively flat featureless area; (iv) A test run was also made over Plen's deposit at Toongi, near Dubbo, in order to obtain and check on the sensitivity of the detecting instrument. The survey techniques used and the results obtained in the several areas are discussed in detail below.

Tasmanian Tiers Airborne Magnetic, Radiometric and Digital Elevation Survey, TAS, 2021, (P5003), Block 5, radiometric line data

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 Tasmanian Tiers Airborne Magnetic, Radiometric and Digital Elevation Survey, TAS, 2021, (P5003), Block 5, radiometric line data were acquired in 2021 by the TAS Government, and consisted of 32951 line-kilometres of data at 200m line spacing and 80m terrain clearance.

L106 Galilee Basin seismic survey, QLD, 1975 Stacked seismic data and images for lines BMR75-A, BMR75-B, BMR75-C, BMR75-D, BMR75-E, BMR75-F, BMR75-G, BMR75-H, and BMR75-I

The Bureau of Mineral Resources made a seismic survey in the western part of the Galilee Basin in the central Queensland in 1975. The aim of the survey was to obtain basic information on the extent and thickness of the western part of the basin, which is entirely concealed beneath the Eromanga Basin. The seismic survey recorded 320 km of continuous single-coverage reflection recording and 18 km of six-fold CDP recording during 87 operating days. Two major faults were mapped. The Holberton Structure, previously known from geological mapping, corresponds to a major fault in the subsurface with up to 300 m of downthrownto the west. Another major fault appears to be a southerly continuation of the Cork Fault. For the other two Galilee Basin surveys, please see L102 and L108.

Discussion [on] "Three foraminiferal zones in the Tertiary of Australia" by M.F. Glaessner

Dr. M.F. Glaessner published his paper in Volume 88, No. 4, 1951 of this Journal in which he describes foraminiferal zones in the Tertiary of Australia and in which he summarises known and unpublished information on the Australian Tertiary sequence. A great deal of precise stratigraphic work has been done on the Australian Tertiary rocks in the past five years. Glaessner knew of this and it is regretted that he did not wait until the results of this work were available. Recent discoveries made since Glaessner's paper was prepared, have made necessary a drastic revision of the age correlations of the Victorian Stages and have emphasised the undesirability of prematurely publishing material based on investigations which are still in progress. A discussion of this paper follows herein.

Intermediate Prospect (1951), Rum Jungle, N.T.

This prospect is situated on the northern bank of the East Finniss River, approximately 500 yards north-east of Brown's workings and 800 yards south-west of White's workings. About 50 years ago the area was prospected for copper and abandoned after several costeans had been dug. A small radiometric anomaly was discovered in 1950 and the area was radiometrically contoured. A geological map on a scale of 20 feet to one inch was prepared by the writer during the 1951 field season, and accompanies this report (Plate 1). [Geology, structure, mineralization, workings, diamond drilling, and prospecting recommendations are discussed].

Radioactive surveys, Katherine - Darwin area, Northern Territory: report for quarter ending 30th September, 1954

This quarter, with its favourable climatic conditions, has seen the greatest activity in the field for the year. Thirteen geologists and five geophysicists, together with many assistants, have operated in the area on many prospects. The Darwin office and laboratory are well-established and providing many services to the public such as assaying, instrument repair, and geological and geophysical advice. Detailed geological and geophysical work has been commenced or continued at the following prospects: A.B.C., Edith River, Burrundie, Brock's Creek and Adelaide River, while minor investigations have been carried out at many other localities. Three drills have operated throughout the quarter. Regional geological mapping has been continued over a wide area. The amount of work being done will decrease during the coming quarter due to the approach of the "wet" season.

Ferruginous manganese deposits, Teano Range, North-West Division, Western Australia

Superficial deposits of ferruginous manganese ore occur on the southern end of the Teano Range, Peak Hill Goldfield, Western Australia at about 150 miles by road north-north-west from Meekatharra. During the course of an investigation of new manganese discoveries in north-west Western Australia by L.E. de la Hunty of the Geological Survey of W.A. and the writer, the opportunity was taken to inspect two groups of small deposits in the Teano Range. One group contains about 14,200 tons of ore which averages about 2 per cent manganese and 32 per cent iron, and the other group 4,000 tons of marginal grade containing about 46 per cent manganese and 3.5 per cent iron. The former group is not of marketable quality and the other is too small and too remote to be of commercial value.

Characterisation of natural gases from west Australian basins

The study provides a comprehensive analysis of the natural gases from the Bonaparte, Browse, Carnarvon and Perth basins (in 4 modules). Geochemical analyses for the molecular and carbon isotope composition were performed on 96 gases and associated liquids, and these data are interpreted in a geological context. Additional non-exclusive data from the AGSO database have been used for correlation/interpretation purposes.
The study addresses factors influencing the composition of gaseous and other light hydrocarbons in natural gas (and associated oil accumulations) including;
-         primary source and maturity controls,
-         secondary alteration processes, e.g. migration fractionation, water washing, biodegradation, and
-         multiple charge histories, including deep dry gas inputs.

Micropalaeontological examination of samples from Australian Oil and Gas Well No. 1, Kurrajong Heights, New South Wales

Cuttings and cores taken between the depths of 30 feet and 4,755 feet in Well No.1 Kurrajong Heights were received from the Australian Oil and Gas Corporation Limited for micropalaeontological examination.  Drilling was discontinued at the depth of 4,766 feet. Attention was given mainly to the fourteen cores submitted but when it seemed necessary to check with the cutting this was done.  No microfossils when found in cores or cuttings until Core No. 17 taken at the depth of 4,656-4,665 feet when foraminifera of Permian age were discovered.  They also occurred in cuttings at 4,670, 4,675, 4,680, 7,705 and 4,725 feet as well as in Core No. 18 at 4,750-4,755 feet, which is all feet above the base of the bore.

New insights and conceptual understanding of groundwater flow in the Georgina Basin, Northern Teriritory and Queensland

The Georgina Basin, covering 358,000 km2 of the NT and Queensland, hosts a regional unconfined aquifer associated with Cambrian carbonate units. As the most reliable source of freshwater in this arid to semi-arid environment, this large, interconnected aquifer sustains communities, industries, and ecosystems. Building on previous studies, our integrated desktop assessment developed a new whole-of-basin conceptualisation of groundwater flow systems and processes within one of northern Australia’s most important aquifers.&nbsp;



We investigated key regional groundwater processes using complementary geoscience datasets. Despite considerable temporal gaps in data across the basin, the extensive spatial coverage of groundwater level and hydrochemistry data, integrated with geologic, hydrologic, topographic and remote sensing datasets, has substantially improved our understanding of regional groundwater flowpaths as well as recharge and discharge mechanisms. We identified three regional-scale groundwater flow systems which differ in their dominant recharge processes. Hierarchical cluster analysis of major ions in groundwater delineates four distinct hydrochemical clusters and helped us identify areas of enhanced recharge. Discharge of groundwater occurs both within and outside of the Georgina Basin, commonly via spring-fed streams and waterholes that support flora and fauna of ecological and cultural significance. Underpinning the interpretation of groundwater data is our new regional hydrostratigraphic framework, which enabled aquifer attribution for over 5,000 bores and expanded the utility of existing borehole data.&nbsp;



Our investigation provides improved understanding of hydrogeological characteristics and groundwater flow dynamics within the Georgina Basin. This knowledge will aid sustainable management of groundwater for current and future users of this critical aquifer system.

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