This report describes the results of a micropalaeontological examination of samples, collected from bores nos. Z.18, T.29, HH.57, and PP.59, in the Moorlands Coalfields.

Rock sample from six localities in northern Australia were submitted for macropalaeontological examination. The rock samples and their fossil contents are described in this report.

A sample of diatomite was submitted for palaeontological examination. The results are of the examination are recorded in this report.

The discovery of the radioactive minerals carnotite and torbernite, in the vicinity of Rum jungle, was reported by Mr. Jack White on the 7th September 1949 in a letter to the Director of Mines, Alice Springs. Officers of the Department of Mines, Alice Springs confirmed his conclusions. The area was visited by J. Daly, J.F. Ivanac of the Bureau of Mineral Resources, and M. Sneddon of the Mines Department, Alice Springs late in September. They suggested that detailed geophysical and geological work should be carried out. H.J. Ward and G.F. Joklik made a detailed geological investigation in October and prepared a map which covers an area approximately half a mile by a quarter of a mile. A general reconnaissance of the country in the vicinity of Rum Jungle was also carried out. In conjunction with the geological work D.F. Dyson made a Geiger-Muller survey of the torbernite-carnotite deposit. An account of this investigation and its findings is set down in this report.

Consequent upon instructions received from the Superintending Geologist, Mr. C.J. Sullivan, the copper-gold deposit at Yeuralba was visited and inspected on the 9th, 10th, and 11th May, 1950. This geological report gives an overview of the inspection and its findings. The situation, history, workings, general geology, orebody, mineralisation, and production history of the deposit are briefly described.

Two methods are outlined in this report. The first, is a method intended for the determination of porosity of consolidated sediments. The method is applicable to those sediments included in rotary drill cores and hand specimens of rock collected in the field. The second, is a method intended for the determination of permeability. It is applicable to suitably sized samples of rocks and any other substances whose constitutions permit of their being treated by the procedure set out in this method, subject to their own inherent limitations relative to this method. This report provides a detailed description of each of these methods.
