This report describes eighteen possible new occurrences of road building material and discusses some general aids in locating and evaluating future deposits. The regional geology of portion of the Jamestown Military Sheet is shown on the accompanying...

Investigation of the deposit owned by Rosewall Sand and Quarrying Co Ltd, into the pressing and extrusion behaviour gives promising results but potential difficulties, such as the relatively low strength of ware in the green and fired state and...

A study of the role of mica in the bloating of clays has been made. Eighteen samples of clay supplied by the Geological Branch of the South Australian Mines Department, were used for the tests, which consisted of heating the samples in an electric...

Samples of clay from deposits at Port Willunga and Berri were tested for possible bleaching activity. They were less effective than commercial fuller's earth. The Port Willunga clay was almost as good as the fuller's earth for bleaching mineral oil,...

Review of methods, mainly from USA, and survey of patent literature.

The property situated in Section 2106, Hundred Yatala between Salisbury and Golden Grove near the scarp of the uplifted Para block, was inspected on August 25th, 1960 to report on tis quarry potential or use for other purposes. The terrain is too...

Marbles in the area mapped are equated with the Lower Cambrian Archaeocyatha limestones found elsewhere in the State. The Cambrian sediments which include arkoses, greywackes, and amphibolites are folded into a broad syncline in Section 113, with drag...

Fourteen power auger holes and three bulldozed cuts have indicated clay containing 45% gypsum under 1m of overburden. Reserves in MLs 661 and 662 on the west margin of a dry lake approach 100 000 t of washed gypsum. Saline water is likely to occur at...

Gently dipping slates and quartzites of the Sturtian series in the Adelaide System rocks occur in the area mapped. A minor drag-fold structure of the quartzites is inferred. Reserves of the residual clay and underlying slates are estimated to exceed...

Three-quarter million cubic yards of Tertiary sands and gravels unconformably overlie Torrensian phyllites, slates and quartzites. More drilling would be required to estimate total reserves. For the sand to fulfil building specifications, the oversize...

Following completion of the report on site investigations a request was received from the Engineer-in-Chief for assistance in location of a deposit of clay suitable for use in a compacted clay lining to the reservoir. Quantity of clay required is of...

More than million cubic yards of quartz-biotite schist are available above road level. The breaking characteristics of the rock must be tested to determine the suitability of the rock for use as road metal.

Sediments in the area mapped in detail belong to the Montacute Dolomite Formation and lower Slate Formation of the Torrensian Series. For the purpose of this report the Lower Slate formation is called the Pinkerton Gully Dolomite formation. Tests...

Surface sampling of windblown shell sands indicated (Johns, 1961) the ready availability of high grade materials on Southern Eyre Peninsula. In particular the deposits situated south of Coffin Bay 25-30 miles by road from Port Lincoln, the nearest...

From a preliminary investigation in an area of Proterozoic Sturtian series rocks 7 miles North East of Radium Hill there appears in excess, both quartzite and ironstone, of the 75000 cubic yards of crushed aggregate required for construction purposes...
