At the present time supplies of screenings for concrete and bituminous work are obtained from a quarry at Watson Siding and it is now desired to establish a quarry near Roadside. On August 16th to 17th 1961 a site where some stripping operations have...

Two dam sites investigated on the Angas River have hard intrinsically sound arkose and greywackes in their foundation areas. The rocks are strongly folded and heavily jointed. Some faulting is suspected in the right abutment of the downstream site and...

The report describes the geology of the area and discusses the effects of jointing, weathering and overburden on design and construction of the road. In general geological conditions are uniform over large areas and the position of the road will be...

The site of a proposed silo at Mt Bryan was investigated by two cable tool holes 8 and 16.5m deep. The drilling intersected Holocene alluvial silty clays. Continuous pad footings would probably be adequate for the site. There does not appear to be any...

The site of a proposed silo at Keith was investigated by means of one cable tool hole 16m deep. The hole encountered very strongly cemented limestone of the Padthaway Formation to 3m, overlying calcareous sand and sandy limestone of the Coomandook...

The foundation conditions of a proposed silo at Site No. 5, Cowell was investigated with the construction of a borehole. Reports for alternative sites 1 to 4 have been issued previously. Subsoil should possess adequate bearing strength in the dry...

The test pits were logged on 27 October 1961. Refer to E.W.S. Survey Plan 122/1961 for location of the pits.

Boring has proved 1½ million cubic yards of basal Tertiary sand under 600,000 cubic yards of overburden to an average depth of 12 feet. The sands lie on an uneven basement of Permian and Proterozoic sediment which shallows to the north. The sand has a...

Eight percussion test bores at selected sites and shallow earth-auger holes on a grid pattern at 50 feet intervals revealed deposits of seaweed of very variable thickness, complex distribution and in various states of decomposition. These deposits...

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...

Sturtian glacial sediments south of Yunta contain haematitic and magnetitic siltstones (banded iron formation) and haematitic and magnetitic tillites formed by chemical deposition of magnetite euhedra in a finer grained haematite groundmass. Both...
