Lunette dunes are associated with a playa lake that is underlain by Blanchetown Clay. At the surface the dunes consist of sandy flour gypsum, but auger drilling disclosed silica sand at shallow depth; thus the dunes do not constitute a commercial...

The Colonial Sugar Refining Co. has expressed a wish to cease the production of gypsum from their Lake MacDonnell leases for several years. They wish to concentrate their production at their leases on Kangaroo Island, to save costs, because they are...

Lake Gairdner is largely covered by a crust of salt which overlies gypseous muds, silts and sands. Despite the fact that the floor of the lake and the surrounding catchment area are underlain by igneous rocks whose K2O content exceeds 5%, the lake...

Laboratory testing of samples from dam and Lake bank exposures has shown the clay to be a high quality plastic type suitable for use in whiteware manufacture. Exposures are limited and a programme of exploratory mapping and drilling is recommended to...

This report deals with the regional stratigraphy of surficial deposits in the region of the Murray Basin and adjoining Gambier Embayment of the Otway Basin. The aim is to place deposits described in selected earlier publications of anthropologists,...

A comprehensive review of mineral deposits and their geological setting is presented to guide planning decisions relating to the mineral industry. The report also provides basic geological, data and literature references useful to mineral exploration...

SA produces the majority of Australian gypsum, and exports 1 third of total production. The major companies and individual producers, the deposits, production, customers, economics of production and export, and competitors, are briefly discussed....

The LINDSAY 1 :250 000 sheet area occupies parts of the southern Musgrave Block and the northern Officer Basin, in the North West Province of South Australia. It is entirely contained by the Great Victoria Desert. The oldest rocks are gneisses of...

Stratigraphic well Muddy Tank 1 was drilled to sample fossiliferous late Jurassic clays. Consequently seen palynological evidence has firmly dated the Algebuckina Sandstone as very late Jurassic (ca. 144 to 141 Ma).

Geological investigations indicate that no major foundation problems are anticipated. Physical testing shows that most materials are suitable as fill. Saline groundwater is available for compaction but no water suitable for concrete or camp use has...

The area embraced by the Andamooka and Torrens 4-mile geological sheets is defined by long 136° 30- long 138° 00 and lat 30° 00- lat 32° 00 and comprises an extensive partially dissected plateau west of Lake Torrens, the Lake Torrens sunkland and part...

Eight cable-tool holes have been completed as part of a program of drilling on the site of the proposed jetty for the Redcliffs Petrochemical Plant. Drilling has revealed a variable succession of unconsolidated sediments. The Marine sands are loose,...

'Industrial minerals' are those minerals or assemblages of minerals which are economically important because of their physical or chemical properties, rather than their metal or energy content. The term is synonymous with 'non-metallic minerals', and...

Safe bearing capacities and recommended footing depths for 18 minor bridge sites between Robin Rise and Marla Bore are presented in this report. Bearing capacities, in most cases presumed, range from 5 to 20 tons/ square foot (500 to 2 000 kN/m2)....

Exploration for possible economic buried sedimentary uranium mineralisation, thought to be associated with an interpreted palaeodrainage EM anomaly originating within Mesozoic or Tertiary strata in two areas near Marree, addressed the potential for...

Site investigations on spring-fed salt lakes in an area north of Snowtown were undertaken to assess their potential for inclusion in artificial pan - confined solar salt production to add to the output of an existing local, seasonal salt harvesting...

A low-lying small area situated 40 km west of Whyalla has been explored primarily for economic gypsum occurrences within Recent surficial sediments, while latterly, a search for metallic minerals has also commenced, via a geological survey of basement...
