Cootanoorina 1 was drilled about 33 miles south-southwest of Oodnadatta township by the South Australian Department of Mines, as a combined 'on structure' and stratigraphic test in the Arckaringa Sub-Basin region of the Great Artesian Basin. The main...

Mount Willoughby 1 was drilled in the northern part of the Arckaringa Basin as a continuation of the SA Department of Mines stratigraphic study of this area. The well was drilled on the western plateau of a positive gravity high on the Wintinna 1 mile...

Yardinna no. 1 well, drilled 20 miles NW of Oodnadatta township intersected the Lower Cretaceous Oodnadatta Formation and bottomed at 512 feet in Bulldog shale also of early Cretaceous age. Both the Coorikiana Sandstone Member, the basal unit of the...

Biostratigraphy of drill core and cuttings was erected for Mt Willoughby, and some biostratigraphy of the Lambina 1 was revised. Problems with contamination were encountered.

Preliminary map was prepared from mapping and shot hole logging. Precambrian crystalline basement is overlain by Permian, Mesozoic and Tertiary sediments. Younger exposed units include gypsiferous clays, sandstone and calcrete.

In June and early July this year, I made two reconnaissance trips to the north of the state to map the western limits of portion of the Great Artesian Basin Sediments. The western extent of the Bulldog Shale (Freytag 1966) and the Coorikiana Sandstone...

Sample taken near an ichthyosaur skull west of Marree yielded an agglutinated foraminiferal fauna of Early Cretaceous (Aptian) age. The matrix of whale vertebra from north of Mount Gambier proved to be Gambier Limestone of Oligocene age.

The Gason 1:250 000 sheet area is centred about 850 km north of Adelaide, in the South Australian portion of the Great Artesian Basin. The area mapped includes most of the Gason Dome, a gentle upwarp in a relatively flat-lying sequence of Mesozoic and...

The NOOLYEANA 1:250 000 sheet area lies in the northern portion of the Great Artesian Basin in South Australia. The area mapped includes the southern part of the Simpson Desert and the very northern end of Lake Eyre North. The oldest outcrops in the...

The PANDIE PANDIE 1:250 000 map area lies in the most northerly portion of the Great Artesian Basin in South Australia. The western half of the area is covered by the longitudinal dunes of the Simpson Desert, while the remainder is covered by (a) the...

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...

Discharge from visited springs in the Dalhousie area was estimated at .86 cumecs. There may be as much as .02 cumecs additional seepage through many smaller seeps in the area which were not visited. The spring waters were alkaline, with a pH varying...

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)....

The LAKE EYRE 1:250 000 sheet area is located about 750 km north of Adelaide on the south-western margin of the Great Artesian Basin. The map area incorporates 15 950 square km, with Lake Eyre itself covering about half of this area. The oldest...

During the last drilling programme, six bores were drilled five of which were completed as water productive. The sixth (viz. Bore 30) is to be completed during the next drilling programme. As in progress report no. 4 the drilling target was the...

The Coober Pedy 1:250 000 sheet area (COOBER PEDY) is bounded by latitudes 29°S and 30°S and by longitudes 133°E and 135°E in the arid north of South Australia. The only town is the opal mining town of Coober Pedy on the northeastern margin of the...

Oodnadatta Town Bore 2 was drilled to supplement the water supply of Oodnadatta, and also to enhance the stratigraphic knowledge of the area. It was drilled to a total depth of 439.48 metres KB, and after pump testing achieved a flow rate of 3.4...
