Report on geophysical surveys of uranium deposits, Mount Painter district, South Australia

The geophysical surveys reviewed in this report were part of an investigation carried out by the Commonwealth Government on behalf of the British Government. Deposits of uranium minerals occurring at several places in the Northern Flinders Ranges of South Australia, and centred about Mount Painter, were subjected to detailed geological examination followed by surface and underground prospecting by means of costeans, shafts, drives, etc. The geophysical work undertaken with the object of assisting the geological examination by measuring the radioactivity of rocks in situ and of hand specimens and assisting the prospecting work by making estimates of uranium content of mine samples. The geophysical surveys consisted of two main parts, namely, field surveys to locate and delineate areas of high radioactivity, and laboratory work to make approximate determinations of uranium content of mine samples by measuring the radiation from them. It is proposed to describe briefly the fundamental nature of radioactivity with specific reference to such features as have a particular bearing on the problems encountered in the field and assay work. In addition, it will be necessary to deal briefly with the geology of the various areas covered by the field work in so far as it effects the geophysical problems.

Evaporite deposits in Australia

Evaporites comprise all deposits formed by the evaporation of water and the precipitation of its constituents, such as calcium sulphate, sodium chloride, and potassium compounds. They may be found as rock-gypsum, anhydrite, rock-salt or potash-salt deposits at depth in pre-Recent geological series, or as Recent formations of gypsum and salt on the surface. The main object of this report is to show the conditions under which evaporite sediments are formed, what salt deposits are to date known in Australia, where rock-gypsum, rock-salt and potash-salt deposits may be expected within pre-Recent formations, and how further investigations should be carried out.

Second report on the possibilities of underground water at Piney Creek, Block 10, Stromlo district, ACT

On 21st November, 1944, a visit was made to the above block at the request of the lessee (Mr. G.D.C. Tanner) who had asked for advice regarding water supply. The report following this visit recommended the testing of an alluvium-filled basin which occupies part of the southeastern quarter of the block. Subsequently Mr. Tanner sank a well at a site about 1,000 feet south of the point indicated as most favourable.  For all practical purposes it may be considered that the well has proved that the alluvium is not capable of yielding a useful supply of water at the end of a dry period, and it became necessary to consider the possibility of obtaining water from the bedrock. The present report embodies results of a further examination with this end in view. The location, topography, geology, and possibility of underground water at Block 10 are discussed in this report. A geological sketch map of Block 10 is included.

Preliminary report on samples from No. 1 bore, allotment 57, parish of Puebla, Victoria (Geelong Flow Oil Co.)

This account of the micropalaeontological examination of samples is presented as a preliminary report. The samples examined were taken from the surface down to the depth of 1,130 feet. The bore is being drilled by percussion methods and consequently there is some admixture of fossil species. However, towards the lower part of the bore, these adventitious species disappear and the species recorded are characteristic of the beds in which they are found.

Beach sands investigation: report on a deposit, 3 miles north-north-west from Lennox Head, New South Wales

The deposits of heavy-mineral sands which are at present being exploited along the East Coast occur on or within a few hundred feet of the ocean beaches. The occurrence of this deposit at a distance of nearly 1.5 miles from the beach suggests the possibility that other deposits may be found at some distance from the coast line. Of incidental interest is the possibility that the deposit, which presumably was formed by wave or surf action, may be at slightly higher level than the deposits adjacent to present day beaches. The locality, examination process, origin, and nature of the deposits are discussed in this report. The results, including estimates of the quantities of heavy mineral concentrates and the grades of the mineral bearing sands, are tabulated here.

Geophysical survey, Roma, Queensland Progress report

In November, 1947, at the joint request of the Queensland Government and four companies which are associated with the search for oil in the area, the Bureau commenced geophysical work in the Roma district of Central Queensland. During the first phase of the geophysical operations, gravity and magnetic methods were applied in the reconnaissance of a large area. The object of these operations was to disclose gravity or magnetic anomalies which might be related to geological structures, indicate the broader structural elements of the sedimentary basin in which the oil and gas occur, and enable areas to be selected for investigation by more exact methods. The purpose of this report is to state clearly the geological problem and the geophysical methods adopted in the attempt to solve it. The geology of the area, possible oil-bearing structures, and the application of geophysical methods to date, are discussed. A sketch map and geological section plan are included.

Notes on aeromagnetic surveys

In the various methods of geophysical prospecting, sensitive instruments are used on or near the surface of the earth to measure effects which arise from differences between the physical properties of rocks, ores and minerals. The analysis and interpretation of these measurements permit conclusions to be drawn concerning the sub-surface geology and the presence or absence of orebodies, coal seams, and the like, or of structures likely to be favourable to the occurrence of oil, etc. The principal physical properties of rocks which are useful in geophysical prospecting are density, elasticity, electrical conductivity, radio-conductivity and magnetic susceptibility. Aeromagnetic survey methods, their present use, and results of such surveys, are discussed in this report.

Wee Jasper-Cooleman Caves area

The Bureau of Mineral Resources and the N.S.W. Geological Survey have jointly undertaken the regional geological mapping of a large portion of the Monaro region of N.S.W. for the Snowy Mountains Hydro Electric Commission. Prior to the present survey, reconnaissance mapping to as far north as a line through Bimbori in the east to Yarrangobilly in the west, had been completed. The objects of the present survey were to continue this map to the north as far as Wee Jasper and, concurrently, to endeavour to ascertain the character, structure, and stratigraphy of the sediments in the western portion of the A.C.T. Field work was carried out in two periods. The first period, of approximately two and a half months from January to March 1950, was spent in a detailed study of the Ordovician beds in the western portion of the A.C.T. and in mapping the area between Wee Jasper and Cooleman caves. The second period was of three weeks duration in February 1951 and was devoted to extending the geological mapping westward to the Goobragandra - Goodradigbee divide.

Report on the Commonwealth mica mine at Yinnietharra, Gascoyne River, Northwest Division, Western Australia

The area was visited in company with Mr. R.S. Matheson of the Geological Survey of Australia in December, 1942, when eleven pigmatite bodies bearing mica and beryl were examined. The report furnished after that visit (1943/2), gives details of access, topography, climate and vegetation which are not repeated here. In view of the urgent demand in Australia for "strategic" mica, i.e. mica of quality equivalent to Clear and Commercial-clear, it was recommended that one deposit at Yinnietharra should be opened and prospecting of others carried on simultaneously. As a result of these recommendations, the Deputy Controller of Mineral Production started mining operations on the selected dyke by open-cutting in June, 1943. Although it was stressed in the abovementioned report that poor exposure of the dyke, on which there were no workings, rendered any estimate of the probable yield of marketable mica speculative, the results actually obtained were far below expectations, and a heavy financial loss on the project was incurred. Consequently, while the question of abandoning the mine was under consideration, a detailed examination of the workings was carried out in June, 1944, again in the company of Mr. Matheson, and the results of this investigation, which was not wholly confined to geological aspects, are embodied in the present report.

Preliminary report on the Crystal King mine, Tallangalook, near Mansfield, Victoria

The presence of quartz crystals in the dump of an old gold mine, known as Black Charlie's mine, in the Strathbogie Ranges led to the reopening of part of the workings in the search for crystal suitable for piezo-electric applications. To date the search has met with success, and has resulted in the discovery of a second crystal deposit adjacent to the old workings. The mine which is now named the Crystal King mine was visited in December, 1944.  The locality, topography, geology, economic geology, and production of the mine are discussed in this report. A sketch section of the mine is included.

The Commonwealth Deep Lead, Glen Innes: proposed geophysical survey

It was recently suggested by Mr. N. White, Superintendent of Minerals Production, N.S.W., that a geophysical survey be made of the Commonwealth Deep Lead near Glen Innes as part of a campaign to prospect for stanniferous wash beneath the basalt cover. In company with Mr. N. White and Mr. E. Dow, an inspection was made of the area on the 7th and 8th October, in order to determine in the first place whether the problem offers scope for geophysical methods. A geophysical survey, if carried out, would commence in the vicinity of what is known as the Commonwealth Mine and the inspection was made primarily of that area. At present there is no activity at the Commonwealth Mine, which is actually the site where some alluvial deposits were first dredged for tinstone in 1909 by the Commonwealth Tin Dredging Company, N.L., on PML 25, Ph. Wellington, Co. Gough.
