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.

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.

This report deals with the results obtained in tests with the electrical resistivity method on the brown coalfields at Morwell and Traralgon, Victoria, in an attempt to develop a rapid method of determining the presence of the coal and its depth below the surface. These tests were carried out in the latter part of 1943 by the Geophysical Section of the Mineral Resources Survey at the request of the Victorian Electricity Commission. Thirty-four resistivity-electrode separation tests were made over a wide variety of geological sections in the parishes of Maryvale, Hazelwood and Loy Yang. These tests were preceded by a number of tests by specific resistivity made on various types of overburden and on coal exposed in the open cuts at Yallourn. This report discusses the results of these tests although verbal information concerning them has already been made available to the Commission's officers. It will be shown that under certain conditions, the predictions of the depth to coal are reliable within fairly narrow limits while under other conditions the predictions are misleading. It is proposed in the first instance to outline the method and apparatus used in these tests. In addition, it is considered advisable to outline the methods of interpretation employed in order that the conclusions reached will by fully appreciated. In addition to discussing the resistivity results, the report deals briefly with the possibility of using gravity methods on the same prospecting problem. Calculations have been made of gravity anomalies to be expected from certain coal sections and it is shown that under favourable conditions this might prove of value in determining the presence and position of the coal.

Report on the possibilities of underground water on Piney Creek pastoral lease. This report follows a visit to the lease conducted in response to a request for advice regarding water supply.

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.

A report on the Lake Cargellico magnesite deposit following a visit on 30th May, 1944.

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.

The Wilks Creek wolfram mine is situated in the parish of Steavenson, county of Anglesey in central Victoria. It is approximately 4 miles south from the small town of Marysville, a popular tourist resort, and 61 miles by road northeast from Melbourne. Underground and surface mapping was carried out on the 23rd and 24th November, 1943, with compass, tape and Abney level. This report comprises an overview of production history, general geology, economic geology and ore reserves.

This report is written primarily to present the determination of the permeability and porosity of a number of rocks and minerals, but it has also been considered advisable to give a brief description of the different kinds of apparatus designed and used in making the determinations. The materials on which the tests were carried out included a suite of specimens from No. 10 bore, Lakes Entrance, two specimens of sandstone from one of the bores at Roma, Queensland, and a number of Australian diatomites. The method of presentation adopted in this report is, firstly to describe the apparatuses used in making the determinations and the technique adopted in preparing the specimens for testing and secondly to discuss the results obtained for each set of specimens. In addition to the permeability and porosity tests already mentioned, a number of tests of compressive strength were made on wet and dry samples of glauconitic sandstone from Lakes Entrance.

The presence of apatite on the southern portion of Alcoota Station has been known for several years. The locality was visited during October, 1944. Two days were spent in the examination of the deposit and mapping. An account of the locality, geology and mineralisation is provided in this report.
