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...

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.

The Pedirka is a Permian infrabasin beneath the western Great Artesian Basin. It lies mainly in the central north of South Australia and the southeast of the Northern Territory but a small part may also extend into Queensland. Much of the eastern...

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...

Materials at Long Creek crossing site are adequate for bridge foundations. Less favourable conditions at the Mabel Creek crossing site will require spread footings with low bearing pressures. Local materials at both sites are suitable for approach...

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...

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).

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...

Two cores from Oodnadatta Town Bore No. 2 were examined for microfossils. A fishing core at about 72m is of Late Albian to ?Conomanian age and is correlated with the Mount Alexander Sandstone Member of the Oodnadatta Formation in Santos Oodnadatta No....

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...

The KOPPERAMANNA map area covers arid stony tableland and sandridge desert on the Birdsville Track, in the Great Australian Artesian Basin about 100 km north of Marree and to the east of Lake Eyre, South Australia. The Cooper Creek crosses the area...

The POOLOWANNA 1:250 000 sheet area is located about 1000 km north of Adelaide, in the extreme north of the South Australian part of the Great Artesian Basin. It is entirely covered by the central southern end of the Simpson Desert. The oldest mapped...

This study has formulated a geotechnical and hydrogeological model of the Wintinna Coalfield which satisfies the following objectives: - to provide answers to the hydrogeological and geotechnical questions raised by Fluor in their mining study; - to...
