Siliceous ironstone in Sec. 201, 3 miles west of Yongala, occurs as scattered lenses within sandy shale on the lower slopes of a hill and as a capping at the top. The scattered and irregular nature of the outcrops allows only the rough estimate of...

The limestones outcropping in and around the Mount Gambler district, have been known as coralline, polyzoal, or bryozoal limestones, but are now generally referred to as the Gambler limestones. They have been the main building material for the...

A deposit of limestone situated adjacent to the south bank of the River Onkaparinga, 4 miles NE of Noarlunga, has been tested by diamond drilling to prove its suitability for road building. The good quality of the stone has been confirmed, although...

Calcination and hydration tests on samples of Murray Bridge Limestones indicate 1100°C as the best calcination temperature. The products contained 72.4, 76.0 and 75.2 per cent calcium hydroxide respectively.

During construction of the green mill at Mount Gambier Government sawmill, cavities were found in excavations for a gangsaw in the Gambier Limestone. Diamond drilling showed the main cavity to be funnel-shaped and not a cavern top, but revealed minor...

Diamond drilling in section 509, hundred Noarlunga, has indicated 400,000+ cubic yards of limestone probably suitable for bitumen aggregate. Further reserves are available over the creek west of this area but extensions to the east will be limited by...

Following the discovery, drilling and grouting of a large cavity in the proposed foundation area for the green milling section of the Mt Gambier Government sawmill, a second large cavity was found in the same area. A further 29 diamond drill holes...

Detailed geological examination of the area in the vicinity of the proposed tunnel has shown that, provided suitable precautions are taken, there are no geological factors which will prevent the successful construction of a tunnel through the ridge...

Three diamond holes totalling 29.03m tested a fine grained sandy limestone in the Pliocene Loxton Sand. The drilling indicated approximately 6000 cubic metres of fine grained building stone, underlain by a similar amount of shelly limestone also...

Permian tillites unconformably overly Cambrian limestones and calcareous slates in the area mapped. Diamond drilling has indicated a weathered zone approximately 20' wide in D.D. Hole No 2 and this is expected to extend through the centre of the...

An investigation of local sources of limestone and dolomite suitable for use in a local steelworks has been initiated. Dolomites in the Middleback Range appear to be chemically suitable but the reserves are limited. Those situated in the Cowell...

Sediments including basalt and limestone of late Pleistocene-early Pliocene age occur on Mount Graham. Both these rock types are considered suitable material for crushing for use as road metal. Reserves of basalt are estimated to be between...

Further geological investigations at the dam site, particularly on the left bank, have delineated the width of limestone present and by means of an exploratory adit have shown that solution cavities are relatively rare. Cavities are of two types;...

Two percussion holes were put down to test the foundations of a proposed silo at Wudinna. No. 1 hole to a depth of 30 feet and No. 2 to a depth of 26 feet. Sealed tube samples were taken in Hole No. 2. The soil profile consists of 6 ft. of...
