This study brings together a wide range of datasets to provide a comprehensive assessment of the Pandurra Formation sedimentology and geochemistry in 3D. This record is associated with both the GA Record and the digitial data release. Sedimentology and geochemistry datasets generated this study are combined with pre-existing data to generate a 3D interpretation of the Pandurra Formation and improve understanding of how the Pandurra Formation as we see it today was deposited and subsequently post-depositionally mineralised. The digital release incorporates the underlying digital data generated this study, the final gOcad objects generated, and reference datasets from Wilson et al., 2011 as required. Study extent in eastings and northings: SW Corner (444200, 6263000) NE Corner (791409, 6726000).

Uranium mineralisation was discovered in association with copper minerals at Rum Jungle in September 1949, and investigations carried out since that time, and which are still proceeding, have led to the discovery of additional occurrences, and have shown that the field is likely to prove an important one. The prospects are mainly uranium-copper deposits, but autunite deposits, which are poor in copper, also occur. In addition, radioactivity has been found in a bed of conglomerate over a length of 2.5 miles. No uranium minerals have yet been positively identified from the outcrop of this conglomerate, which shows no sign of sulphide mineralization. This paper presents a preliminary account of the geology and type of mineralization in the Rum Jungle area.

The most important known deposits of what are commonly referred to as the beach sand minerals are situated along the most easterly part of the Australian coast. The geographical distribution, physiography, formation, origin, composition, and reserves of heavy minerals along the east coast are discussed in this report.

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).

Boring commenced in the Broadbeach area on an East-West line 500 feet south of the northern boundary of DC22. Subsequent boring was carried out along lines 1300 feet, 2100 feet, 2900 feet, 4500 feet, 6125 feet, 7740 feet, 9300 feet, and 10900 feet south of the northern boundary of DC22. The results of the beach sands investigation are presented here. Estimates of the tonnages of heavy-mineral concentrates, the average grades of the heavy-mineral bearing sands and the average thickness of overburden, are tabulated. The complete set of data, from which these figures have been calculated, is attached as an appendix to the report.

An area of about 190 acres lying within the boundaries of Allotment 26D, Budgeree, County of Buln Buln was taken up for prospecting purposes on 21st May, 1947. The topography, general geology of the area, and the occurrence, volume and grade of the bauxite bodies, are discussed in this report. Three accompanying plans are included.

During the period 10th October to 15th November 1950, the writer visited the Rum Jungle area in order to direct the local and regional geological mapping, with a view to establishing the geological relationship between the various prospects, the manner of occurrence of the ore bodies, and if possible the control of mineralisation. Owing to the short time available for the field work, the present report must be regarded as a critical preliminary study of the area to aid future planning, rather than a complete investigation. Only the broader aspects of mineralisation are dealt with in this report.

During the last three years much work has been done on laterites in Northern Australia by geologists of the Bureau and in particular those attached to the North Australian Regional Survey. The co-operation of soils officers and geologists in this survey has led to a better understanding of the significance of laterites and of the zones within the profiles. Since several parties from the Bureau are now working in Northern Australia it seemed opportune to discuss the nomenclature of laterites and to suggest terms and definitions so that laterites can be described and mapped in the same way by the several field parties. With this object in view geologists from the Bureau and officers from the North Australian Regional Survey discussed the matter and the following terminology and definitions are circulated now for criticism within the Bureau.

In October, 1951, the Geological Section of the Bureau of Mineral Resources recommended a geophysical survey at the newly-developed Rye Park tungsten deposit. The purpose of the survey was the delineation of the main mineralised areas around a granite cupola. The geology of the area, survey methods, and field operations are described in this report. The result of the survey and of diamond drill hole testing are discussed.

The Northern Territory is an integral part of the great Australian Pre-Cambrian shield which underlies almost the whole of Western Australia and the Northern Territory, much of South Australia and portions of New South Wales and Queensland. In most parts of the Continent, Pre-Cambrian rocks were welded into a stable shield before the end of Pre-Cambrian time, and in the Northern Territory itself the structural framework was established, and most of the mineral deposits introduced by an orogeny which terminated geosynclinal sedimentation about the end of the Lower Proterozoic. This discussion of the structure of the Territory in relation to mineralization is mainly concerned with Pre-Cambrian, and in particular with Lower Proterozoic rocks. Only a broad outline of the subject is given here.
