  • This report gives the result of a microscopic examination of a small collection of fossiliferous rocks from the glauconitic deposits at Maslin Beach and of material collected by Sir Douglas Mawson from the vicinity of Aldinga Bay. Only the micro-fauna has been investigated as the mega-fossils have been described by many palaeontologists.

  • This report deals with all the known bauxite deposits at Ouse including one occurrence on Cleveland Estate. This report comprises notes on the general situation, access, geology, and bauxite reserves at Ouse, along with descriptions of the individual deposits.

  • Brief descriptions and estimates of the size and grade of the more important known uranium deposits in various parts of the world.

  • Asbestos has been mined from an open cut in portions 122 and 12 of the Parish of Yulgilbar, County of Drake. There are a few outcrops of rock in the immediate vicinity of the known deposits, and this renders geological interpretation of the area difficult. Because of this an extensive programme of development has recently been undertaken including drilling, trenching, shaft-sinking and driving. The geophysical surveys made were intended to assist the development, where possible, by outlining the probable extent of asbestos deposits, elucidating structural features associated with the deposits, and providing any information that would assist the geological interpretation of the area. The objectives, survey methods, and results of the survey are discussed in this report. Seven accompanying plans are included.

  • It is considered that the future of the Mount Bischoff field depends on the success or failure attending efforts to find additional payable ore. The problem then is to locate large tonnages of replacement ore either as extensions of known orebodies or as new orebodies. The results of the campaign outlined in this report will be of paramount importance to the maintenance and development of the field, and the campaign should be conducted energetically by diamond drilling, supplemented by underground explanatory work. The geological interpretation, objectives of the drilling, and proposed drilling campaign are outlined in this report. Three accompanying geological plans are included.

  • A report on the testing of bauxite deposits in the Tasmanian districts of Ouse, Launceston, Rosevale and Myalla. This report is supplementary to Mr. Owen's report (1946/2).

  • A visit was paid to Gidleigh Station on Saturday, January 12th. The ten bores previously put down on the property were examined. Details including depth, flow, elevation, and the results of observations made at the site, are given in this report.

  • The principal alternative sites for an administrative centre which have been considered or suggested are discussed from the points of view with which a geologist and vulcanologist is primarily concerned - namely vulnerability to volcanic action, earthquakes, and tidal waves, foundations, water supply and accessibility of material suitable for road resurfacing, aggregate, etc. The areas considered are Rabaul, Nonga-Tavui, Keravat-Kabaira, Vunakanau-Taliligap, and Koko-Rapopo.

  • An overview of the occurrence and testing of bauxite deposits in Australia.

  • The Harold's Cross Barite Deposit lies 7.4 miles slightly north of east from Captain's Flat. Four separate deposits were noted, each occupying a minor shear or joint plane in the granite. The past production and geology of these individual deposits are discussed in this report.
