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.

This report concerns a geological reconnaissance made of a portion of the Kosciusko area and the preliminary geological plan compiled from air photographs and field observations. General geology, engineering geology, water problems, and proposed works for the hydro-electric scheme are discussed in the report. Three geological plans are included.

Five occurrences of ferruginous bauxite near Rosevale were examined and two of them (Nos. 3 and 4) mapped in detail on a scale of 100 feet to 1 inch. It was felt that Areas 3 and 4 which offered some slight chance of successful development should not be abandoned until a few test-pits had been sunk to confirm or disprove the conclusions reached from the surface inspection. Descriptions of the general geology, individual bauxite occurrences, and testing results are given in this report. A locality plan is included.

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

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.

Progress report on the testing campaign, commenced in May, 1945, of the bauxite deposits at Ouse, Tasmania, No. 2 Area.

Two earlier reports on this subject dealt with this industry on the basis of information then available and virtually omitted from consideration the activities of the producer and consumer subsidiaries of the Colonial Sugar Refining Company. This company has now supplied detailed information, particularly on its plans for production and it is therefore necessary to review the industry afresh. The production and consumption of asbestos in Australia are discussed in this report.

In response to a request from Mr. W.H. Williams, Director of Mines, Tasmania, a geological survey was made of the asbestos deposits situated near the tunnel on the Emu Bay railway, 5 miles north-east of Zeehan. A programme of investigation was set out involving a detailed survey of the deposit, prospecting and development work, an assessment of potential fibre grades and ore values, and research into milling practice and market utilization of fibre. The geological survey and related investigation, which are the focus of this report, were concerned mainly with the first three items. Three plates, including a geological map, surface plan, and a plan showing underground workings and effective grades, are attached to this report.

The Pioneer tungsten-bismuth mine, Hatches Creek, was discovered in 1917 and worked on a small scale from then until a short time after the conclusion of World War I, when production ceased owing to a fall in tungsten prices. Prices rose again in 1937, and exploration resumed. The general geology, ore bodies, and working of the Pioneer mine are discussed in this report.

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.
