  • A visit of one month was paid by the writer to the North-West Basin and the Fitzroy area of the Desert Basin. It is largely due to the careful planning of the excursions by the Senior Geologists in charge that a coherent picture of the stratigraphical and tectonical conditions was obtained within the comparatively short time at disposal. This note contains a few remarks on the stratigraphy and tectonics of both areas in connection with oil prospects.

  • During the period 29th September to 2nd October 1950, the writer and geologist N. McKay, investigated the area near Wyndham, in which Mr. N. Orchard claims to have obtained a pitchblende sample in 1919. Following the examination of the area referred to by Mr. Orchard, an examination was made of a supposed radioactive deposit reported by Mr. E. Crocker of Wyndham. The observations made during these investigations are described in this report.

  • This report comprises descriptions of certain rocks collected by Dr. H.G. Raggatt in the Torquay - Airey's Inlet area, Victoria. The rocks are isolated specimens and no general conclusions applicable to the group as a whole have been drawn.

  • During May, 1950, a sample of granitic material was obtained from a dump on the Sunnyside goldfield, and showing a few flakes of a green mineral similar in appearance to torbernite, was forwarded to the Department of Mines, Melbourne, by a miner working on that field. The Mines department tested the mineral and proved that it was uranium-bearing, and submitted a sample to the Bureau to test for radioactivity. After confirmation of the presence of radioactivity in the sample by laboratory tests, a brief visit was paid to the field by a party from the Geophysical Section. One day was spent for conducting tests on the field. The opportunity was taken of visiting the Maude and Yellow Girl mine, and testing ores and concentrates for radioactivity.

  • The core sample of grey marl was collected from the No. 2 Bore, Parish of Glencoe South, and came from the depth of 110-125 feet. The results of a micropalaeontological examination of the sample are described in this report. The species of foraminifera recognised in the sample are listed.

  • A micropalaeontological examination was conducted on core samples from bores at Collie. The results, which comprise detailed descriptions of the samples, are recorded in this report.

  • This report contains the results of a brief examination carried out from 1st to 7th October 1950 at Maranboy, Northern Territory, by the writer and Dr. J. Sleis, Geologist, who were assisted by the Inspector of Mines, Mr. W.A. McDonald. The purpose of this examination was to obtain the necessary data for a preliminary assessment of the tinfield based on the ore developed and won to date.

  • An examination of the deposits took place from 29th June to 13th July, 1950. Very heavy rains hampered the work, but it was possible to make a careful examination of the volcanic areas, and also to gain a general idea of the geological conditions. Some mapping was carried out by compass-pace methods but it is evident that more detailed surveying, with the use of aerial photographs, in order to produce a geological map of the D'Entrecasteaux group, would be worthwhile. An account of this examination and its results is given in this report. The general geology of the area and vegetation are described. The location, nature, extent and destruction of the sulphur deposits are discussed. A note on clays resulting from hydrothermal action upon volcanic flow rocks is appended.

  • This report gives an overview of the known bauxite resources of Victoria. Descriptions are given of the general geology of the area, of the individual deposits, and of the bauxite.

  • This report gives an overview of the bauxite resources of Tasmania. The report provides a summary of the work, investigation, and sampling conducted between 1941 and 1949. The mode of occurrence and types of bauxite are described. A description, which includes a statement of reserves, is given of each of the eleven individual deposits.
