Geophysical observations were carried out in conjunction with a geological survey of the Peake Denison Ranges during the winter of 1953. To the east of the main range geophysical evidence would indicate a gradual shelving of bedrock, deepening to the...

In February 1951, South Australian Barytes Limited became interested in this mine, held under claim by Reginald John Alfred Larsson and requested an inspection by Department of Mines officers. This request was repeated, and endorsed by Larsson in...

An occurrence of barite mineralisation located in the eastern valley wall of the River Torrens gorge, 16 miles east-northeast of Adelaide, which lies on freehold property and has been privately mined in the past, was inspected in order to gauge its...

A gravity survey was carried out at Iron Knob, during the period 28th July, to 14th August, in accordance with the recommendations and decisions made after the completion of the geomagnetic survey over the same area (vide progress report No. 3). A...

An unsucessful attempt has been made, by gravity and magnetic methods, to locate the presumed extension of a fault in Adelaide System rocks near Kapunda.

Magnetic and gravity investigations have clarified the form of the magnetic anomaly near Curramulka. Considerations of depth, anomalies over other iron-bearing rocks on Yorke Peninsula and other factors suggest that further work is not warranted.

The degree of success achieved by geophysical methods in the search for iron ore north of Iron Knob has prompted a re-appraisal of the results of magnetic and gravity surveys carried out by the writer in an area west of Camel Hill in 1952.

One of the magnetic anomalies noticed in the aerial magnetic survey of the Maitland Military Sheet has now been investigated in some detail. A preliminary ground reconnaissance disclosed the presence of two large magnetic anomalies in the vicinity of...

Three gravity traverses have been measured over the Katunga Hills in order to investigate the similarity of the gravity anomaly over them to an anomaly of magnitude 6 mGal just north of Iron Knob. An anomaly of magnitude 3-4 mGal was found centred on...

This report summarises regional geology and the results of geophysical surveys and drilling. Ultrabasic rocks underlie the centres for each aeromagnetic anomaly and are sufficiently dense to account for each gravity survey. Spectrographic analyses do...

Ten diamond drill holes were drilled to assess the reserves available for quarrying at the Roadside (Maralinga) Quarry and to test its suitability for concrete and road aggregate. Drilling revealed dolomite reserves of 190,000 cubic yards. Large...

As part of the SADM iron exploration programme in South Australia, geophysical and drilling investigations have been undertaken on the Warramboo Anomaly, the largest elongate asymmetrical aeromagnetic anomaly in the State outside of the Middleback...

Results are reported of laboratory firing tests made on 11 shale samples and 4 clay samples, performed in both oxidising and reducing furnace atmospheres for various length heating periods over an extensive fusion temperature range. The bloating...

Twelve holes have been drilled on gravity anomalies to test for the presence of Triassic coal bearing sediments. The area covered extends from the North Field, Leigh Creek to north of Lyndhurst. No coal or Triassic sediments were intersected in any of...

A gravity survey was made over the Willunga Basin, an area of Eocene to Recent sediments resting on a Cambrian and Precambrian basement about 25 miles south of Adelaide. It is considered that the Bou51/1guer gravity anomaly indicates the thickness of...

The results of this investigation show a small gravity "low" over the structure suggesting that the rock formations beneath the central portion of the Dome are less dense than those comprising the surrounding area. No significant magnetic variations...
