  • This report summerises the kinds, sources, and handlers or processors of asbestos in Australia, 1944.

  • The testing programme described herein is the result of a recommendation made in a previous report. Twenty-four boreholes were put down during October, 1944, to determine the extent and quality of the bentonite and associated clays. During the early part of the boring campaign the area was surveyed in detail by plane-table with the assistance of the Queensland Geological Survey. The details and results of boring, origin of the bentonite, micro-fossil content, testing, and reserves are discussed in this report. Logs of Boreholes, a plan of the bentonite deposit, and cross section diagrams are included in the report.

  • The presence of foraminifera in the Permian sediments of Australia was recorded as early as 1882. Some systematic work was done up to 1905, but there was no further investigation into these micro-fossils until 1937. A considerable amount of research is still necessary before it can be stated whether or not a definite system of zoning, based on micro-faunas, can be applied to the Permian rocks of Australia. It seems possible, however, that certain species may be characteristic of the Upper and Middle Permian deposits. In the extensive collections of Permian rocks examined from the Hunter River District in New South Wales, assemblages of foraminifera rather than restricted species have proved useful for zonal purposes and this method of zoning should prove valuable when more material is examined from the Permian deposits of other States.

  • Results of micro-examination of samples from Bore No. 3825 on E.W. Langbien's property near Bourke, from 950 feet down to 1200 feet.

  • In the search for oil in Queensland, Drillers Limited, a subsidiary of Oil Search Limited, Sydney, put down a deep bore at Hutton Creek near Injune, in the parish of Simmie, county of Westgrove and 60 miles north of Roma. Drilling operations, which began in 1935 and ceased in 1938 when the depth of the bore was 4,688 feet, were carried out with a Commonwealth Government plant. The major part of the drilling was done by the percussion method, but cores were taken at various depths down to 4,678 feet. No samples were received for microscopic examination until the bore reached the depth of 650 feet, but from this depth to the bottom of the bore-hole, 638 samples of cuttings and cores were examined. Findings from a study of these samples are recorded in this report.

  • In the years immediately preceding the present war, 75 per cent of the world's production of tungsten concentrates came from southeast Asia; approximately 50 per cent came from China. This production consisted almost wholly of wolfram. With the entry of Japan into the war in 1941 and its occupation of Indo-China, Thailand and Burma, these supplies were cut off from the United Nations. This cessation of supplies made it necessary that all countries amongst the United Nations should make intensive efforts to increase their production of tungsten ores and concentrates. In Australia, the effort was necessary in order that as much tungsten concentrate as possible could, after domestic requirements were satisfied, be exported to Great Britain and the United States of America. As the King Island Scheelite Mine was (and still is) the largest producer of tungsten concentrates in Australia, the possibilities of increased production from the that mine were among the first to be considered.

  • Gibsonvale tin field is situated approximately three miles southeast of the village of Kikoira. This preliminary report was prepared following an examination of the tin field by the writer. Aspects of the general and economic geology of the field are discussed herein.

  • No. 1 Bore, Arcadia is situated in the parish of Arcadia, county of Westgrove, 85 miles north of Roma and 40 miles north-north-east of Injune, the nearest rail town. Drilling operations extended from 1936 to 1939. The Arcadia bore it the second deep bore in Queensland (the first being Hutton Creek bore) from which a comprehensive series of samples has been examined for their micro-faunal content. This examination was carried out on 1,256 samples consisting of drill cuttings taken over every five feet and of cores taken at numerous depths below 4,112 feet.

  • Palaeontological notes on four rock samples from the Northern Territory.

  • The majority of the foraminiferal species in the samples submitted have been found in the drill cuttings from the Artesian Bores around Bourke and Mungindi in northern New South Wales and the tests are in the same condition of preservation. The species recognised in these samples are listed in this report.
