Geophysical investigation of the copper-nickel deposits, North Dundas field, near Zeehan, Tasmania

In response to applications by the Tasmanian Department of Mines and the interested company, Eagle Metal and Industrial Products Pty. Ltd., Tasmania, a geophysical investigation, including self-potential, electromagnetic and magnetic surveys, has been made over the copper-nickel deposits of the North Dundas Field, situated about 5 miles north-east of Zeehan, Tasmania. The nickel ore occurs in the foot-wall of north-striking ultrabasic dykes. The ore shoots already worked had proved very rich but quite small. Important results were obtained in the Cuni North Area only. Conductive indications which appear to be due to mineralization extend over a length of 800 to 1000 feet. The line of mineralization is intersected by cross faults. Drilling targets for five short diamond drillholes are given. Further exploration should be confined mainly to this area. The geophysical results indicate that mineralization farther south is limited in extent and perhaps of no economic interest.

Uranium-copper deposits, Rum Jungle, Australia

Uranium mineralisation was discovered in association with copper minerals at Rum Jungle in September 1949, and investigations carried out since that time, and which are still proceeding, have led to the discovery of additional occurrences, and have shown that the field is likely to prove an important one. The prospects are mainly uranium-copper deposits, but autunite deposits, which are poor in copper, also occur. In addition, radioactivity has been found in a bed of conglomerate over a length of 2.5 miles. No uranium minerals have yet been positively identified from the outcrop of this conglomerate, which shows no sign of sulphide mineralization. This paper presents a preliminary account of the geology and type of mineralization in the Rum Jungle area.

L097 Seismic reflection and refraction survey in Ngalia Basin, NT, 1969Traverses A, B, C, D, E, F, G, H, I, J, K, L, M, N, and O

The Bureau of Mineral Resources made three seismic surveys in the Ngalia Basin, Northern Territory, during 1967 to 1969 as part of a comprehensive geological and geophysical investigation of the structure and stratigraphy of the basin. L097 is the third survey done in 1969.

The project was aimed at delineating the configuration of the basin, within which outcrops are sparse, and providing information pertaining to its depositional and tectonic history. Investigation of the extent of Lower Palaeozoic sedimentation was considered to be important in assessment of the petroleum prospects of the basin.

Interim report: geophysical investigations of the copper-nickel deposits, North Dundas field, near Zeehan, Tasmania

The Bureau of Mineral Resources has commenced a geophysical investigation of the copper-nickel deposits in the Five-Mile district near Zeehan at the request of the Tasmanian Department of Mines, Hobart. The Department, in its Summary Report (1952) has indicated the possibility that further ore-bodies of economic value exist in the area. Therefore, the Bureau was asked to carry out a geophysical investigation of the whole area. The Department of Mines laid out the lines including cutting and pegging the traverses. The geophysical survey was begun in May, 1952, with a programme including self-potential, magnetic and electro-magnetic measurements. This interim report has been prepared to present the geophysical results obtained to date and to discuss their significance. Self-potential and magnetic results are discussed.

The micropalaeontology of the Giralia Anticline, north-west Australia

The Giralia Structure is an eroded, doubly-lunging anticline about 60 miles in length and 10 miles in maximum width. It is situated between Exmouth Gulf and the Lyndon River near the coast in the North West Division of Western Australia. In this investigation micropalaeontology has been applied to help in elucidating the surface stratigraphy of the eroded Giralia Anticline. The chronology, correlation and palaeo-ecology of the exposed sediments must be considered in evaluation their oil-possibilities. To this end examination of microfossils, principally foraminifera, aids materially in recognizing unconformities, structural conditions and facies changes, in dating and correlating strata and in interpreting ancient depositional conditions. The samples studied were collected by a field party of the Bureau of Mineral Resources during the winter months of 1950 and 1951. Additional samples were collected by the writer in visits to the area in July 1950 and July 1952.

L108 Galilee Basin seismic survey, QLD, 1976 Stacked seismic data and images for lines BMR76-01, BMR76-02, BMR76-03, and BMR76-04

The Bureau of Mineral Resources conducted a seismic and gravity survey in the eastern Galilee Basin area from August to December 1976. Two traverses of the survey were recorded in the Clermont-Alpha area. Both traverses were recorded to investigate the relations between the Galilee, Drummond, and Adavale Basins in this area. Traverse 3 was recorded as a continuation of BMR 1971 Traverse A and extended this traverse to the outcrop of the Anakie Metamorphics. Traverse 4 was recorded to provide a tie between Jericho No. 1 well and the outcrop of the Drummond Basin Sediments on the Capricorn Highway. For the other two Galilee Basin surveys, please see L102 and L106.

Geophysical investigation at the Commonwealth Mine, Wellington, New South Wales

Wellington is a small town on the Macquarie River about 200 miles north-west of Sydney (see Plate 1). These are several old mine workings - shafts, pits, costean, etc. - about 7 or 8 miles south-east of the town. Massive sulphide ore has been found and developed in one of these workings, namely, the main shaft of the Commonwealth Mine. A fairly big dump, which shows signs of good ore and some smelted material, is evidence that there was once a good bit of mining activity in the area. In 1951, the Consolidated Zinc Corporation became interested in the abandoned mine and arranged for the lease owner, Mr. George Wilkins, to de-water it. As pointed out in the report of the Company's geologist, nothing is known from the numerous old workings regarding the extent of the sulphide orebody. The purpose of the geophysical investigation was to determine if there is any extension to the known orebody and to provide the Company with drilling targets. The geophysical work was carried out from the end of July to the beginning of September, 1952, and it covered the whole of the old mining area, some 6,000 feet in length. The Consolidated Zinc Corporation carried out the necessary surveying work, such as pegging and levelling traverses, and the Company's drilling party assisted where necessary. The general results of the survey were discussed with representatives of the Company as soon as the field work was completed.

Summary statement of Australian bauxite reserves at 30th June, 1953

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 so as to be consistent with the statements for other States. 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.

Preliminary report Tuluman Volcano, Lou Island, St. Andrew Strait, New Guinea

On the 12th July the writer was informed by signal originated by the A.D.O. Baluan Island, that explosive activity had recommenced at the St. Andrew Strait vents. The writer departed Rabaul by air from Momote on the 14th July and arrived at Baluan per Administration work boat on the evening of the 15th July. En route to Momote on the evening of the 14th a brief aerial inspection was made of the active area. Two small craters were visible above sea level and some minor explosions originated from the western crater during this inspection. The writer spent one week in the area and departed Baluan on the 21st July. During this period, as no further explosive activity was manifest, two ground inspections were made of the western crater. The day after the writer departed Baluan mild activity (mainly effusive) recommenced at the eastern crater. The name Tuluman (Tuluman being the word for hot in the Manus language) has been proposed for this new volcano. The name embraces the whole of the structure, that is, the two small cones above sea level as well as the submarine portion of the structure. The two small structures above sea level are referred to as east and west Tuluman craters respectively.

Geophysical survey at Tallawang magnetic deposit, Gulgong, New South Wales

Geophysical surveys of the magnetite deposits of Australian Magnetite Pty. Ltd. at Gulgong were made by the Bureau in 1952 and 1953, and revealed that the Tallawang deposit was the most important one. The present report gives the results of a detailed magnetic survey which was made over this deposit in August, 1953. Results show that three concentrations of very strongly magnetic material exist within the Tallawang deposit. The southern concentration is unlikely to contain considerable reserves beyond those in sight. The central concentration has been partly worked and could yield reserves of ore from the west wall of the quarry. The northern concentration, which has not been worked, could yield limited reserves. It is shown that the deposit, as a whole, pitches northwards. Some exploratory drilling is recommended on each of the three concentrations.

Report on volcanic activity on Ambrim Island 1950/51

Benbow crater is the main residual active centre of the large ancient volcano which has formed Ambrim Island. For the eleven months preceding December 1951 it has been the source of extraordinarily intense and prolonged explosive activity. The volume of ash and scoria ejected during this period exceeds 800,000,000 cubic metres. Evidence has been found during the recent inspection of this volcano that suggests that the current phase of explosive activity has ended. The 1950-1951 eruption, possibility of future activity, and effects of the eruption, are discussed in this report.

Condensed progress report on the geology of the Carnarvon (North-West) Basin, Western Australia

A geological investigation, directed mainly towards the assessment of oil potentialities of the Basin, was commenced in 1948 by the Bureau of Mineral Resources, Geology and Geophysics when a small geological party carried out a reconnaissance of the Minilya River area. Since then up to seven geologists of the Bureau under the direction of M. A. Condon have been mapping the area in some detail each year in order to determine the stratigraphical sequence and its variations, regional structure, and the anticlinal structures and their extent. In addition to the regional mapping the two largest anticlines were mapped in detail. Geophysical work (gravity and seismic) has been carried out by the Geophysical section of the Bureau (see Record 1954/44). More recently, Seismograph Services Ltd. carried out a seismic survey for West Australian Petroleum Pty. Ltd. - mainly for the purpose of checking on the location of its first deep test, which is now being drilled on the Rough Range Anticline with some encouraging results to date. Palaeontological, petrographical and chemical examinations of specimens collected in the field are still continuing by specialists of the Bureau and outside.

Results of drilling for open-cut coal in the Bloomfield area, Newcastle region, NSW

During late 1951 and early 1952 the Bureau, while searching for open-cut coal in New South Wales, prospected the Big Ben and Donaldson's Seams in the Bloomfield Area which is 3.5 miles south of East Maitland. Drilling involving 21 holes and totalling about 2400 ft. revealed that although the actual coal of the seams was quite good in parts, the seams themselves were subject to marked bending, thinning, and splitting. This not only severely limits open-cut prospects to small areas but will make mining difficult.  In the contiguous East Bloomfield, Stoney Pinch and Thornton Areas an additional 16 holes with a total footage of 2,250 feet were drilled and indicated that the seams were characterised by the same rapid variation and offer no better possibilities than the main Bloomfield Area. 

Operations, including mining, coal analyses, logging, and surveying are discussed. Bore logs and the results of coal sample analyses are appended to this report.

Seismic investigations in the vicinity of the railway line between Wodonga and Albury, Victoria

The refraction seismic tests described in this report were made at the request of the Victorian Railways Department. The work was located within the railway reserve between the outskirts of Wodonga township and the River Murray, and consisted of the shooting of five refraction traverses, set out approximately parallel to the railway line and covering in detail a total length of 4,800 feet. The aim of the seismic work was two-fold. Firstly an investigation was required of the subsurface formations in the vicinity of the bridges which carry the railway across several creeks intersecting the Murray flood plain. The subsurface information is required in connection with the design of the foundations of new bridges which will be constructed to replace the existing ones. The second purpose of the work was to test whether the refraction seismic method would be suitable for adoption by the Railways Department engineers as a standard routine method for investigating foundation conditions. To fulfil this purpose ideally, the method would need to be applicable generally to all the foundation problems encountered by the Department and to completely eliminate the necessity for test drilling of sites. The flood plain of the Murray, on which the seismic measurements were made, is composed of Recent alluvium, probably underlain by Tertiary river deposits and is crossed by several creeks and anabranches of the main stream. The outcrops in the vicinity of Wodonga show the bedrock to be granite and metamorphic sediments. The field work was done between February 26th and March 12th, 1953. The field party comprised two geophysicists and three field assistants provided by the Railways Department.

Notes on a lepidocyclina-bearing rock from Cebu, Philippines

During a visit by the writer to the Philippines in November, 1953, specimens of a large Lepidocyclina of paper-like thinness from the island of Cebu were handed to her for comment. External characters immediately suggested Lepidocyclina (Eulepidina) badjirraensis Crespin, from Badjirrajirra Creek, Cape Range, Exmouth Gulf, North-West Australia (Crespin, 1952). Thin sections prepared at the Bureau of Mines, Manila, confirmed this determination. A special visit was made by the writer to Cebu to collect specimens from the locality at Mantalongan. In company with Mr. Robert Grey and other members of staff of the Bureau of Mines, she set out from Cebu City for the locality, but owing to heavy rains, which brought about a sudden rise in the height of the river to be crossed, it was not reached. However, it was promised that a collection would be made at the earliest opportunity and forwarded to Canberra. These samples were received from the Director of Mines, Manila on 28th July, 1954.
