Base metal exploration activities undertaken by Thiess Brothers in the Yumali - Coomandook area investigated several coincident regional gravity and aeromagnetic anomalies arising from concealed Palaeozoic basement rocks. These anomalies are part of a...

The following Tertiary units were identified : Kongorong Fm, Narrawaturk Fm, Buccleuch Fm, Ettrick Fm, Mannum Fm, Kalibar Limestone, Parilla Sand and North West Bend Fm. All of these units are separated by unconformities. Erosional surfaces,...

A multi-commodity mineral exploration programme carried out over an area between Mannum and Strathalbyn, seeking buried targets concealed in Tertiary sediments and basement rocks, comprised aerial magnetic, radiometric and EM surveys; groundwater,...

The stratigraphy of the Comaum 2 bore was revised and corrected. Tertiary sediments extend to 146m, and at this depth are dated as Paleocene on microfloral comparisons with south-western Victoria. Most of the Eocene section of the Knight Group (now...

Gas was reported effervescing from a water bore of 256 feet depth near Ki Ki, South Australia. The water was sampled on May 11, 1965, but hydrocarbons were detected in the gas above the water in the sample bottle. There was a petroliferous smell from...

The Murray Basin is an area of Mesozoic and Tertiary sedimentation divided into two main units the Murray Basin proper separated by structural highs, the Padthaway “Horst”, from the Gambier Sunklands. Knowledge of the Mesozoic in the Murray Basin...

Coonalpyn Town Water Suply bore No. 2 is selected as the standard subsurface section for beds of the Buccleuch Formation (formerly Buccleuch Group) of Late Eocene age. The bore penetrated Bridgewater, Coomandook and Buccleuch Formations and was...

A water bore put down for C.O. Kllitschner on secn 10 Hd Strawbridge recovered a rich Eocene foraminiferal assemblage from limestone of the Buccleuch Formation between 26 and 62m, The horizon is overlain by Gambier Limestone, and overlies sericitic...

Well (100 metres) intersected 6 thin low yielding aquifers mostly in Tertiary and Permian sands.

Shelly fragments amongst poorly sorted, dark grey subrounded quartz sands below Murray Group limestones were examined. It was believed that these might equate to marginal marine or paralic facies of Late Eocene Buccleuch Group. The earliest Tertiary...

A drill core sample of white bryozoal limestone taken from 156.9 m depth in hole Caringa 1 drilled near Karoonda in the Murray Basin was dated palaeontologically using the sediment's foraminiferal fauna. An early Late Eocene age was determined, which...

A regional groundwater model has been constructed of the Loxton Sands watertable aquifer in the eastern Riverland, over an area extending eastwards from Overland Corner to the State border. It is being used to quantify the salt load impacts on the...

Nine rotary mud groundwater investigation holes were drilled by SADME on the Murraylands Coastal Plain between July and November 1989, to total depths of between 82 m and 204 m. Composite logs of these holes are presented herein, together with those...

The study area is underlain by two aquifer systems - unconfined Cainozoic marine limestones and confined Tertiary fossiliferous limestones and sands. Both aquifers contain saline groundwater which is flowing slowly to the west under low gradients....

Foraminiferal investigation of 3 SADME groundwater observation bores in relation to 2 already studied, resulted in the recognition of lithologically uncharacteristic marine Tertiary units on the margin of the Angas / Bremer Irrigation Area. A...

Nine observation wells were drilled in the SW Murray Basin between Goolwa and Salt Creek to monitor groundwater levels and salinity in the confined Renmark Group / Buccleuch Group aquifer. The area of interest is underlain by the Padthaway Ridge of...

The Cambro-Ordovician basement underlying Murray Basin sediments in the Cooke Plains and Coomandook areas was sampled by a reverse circulation drilling programme as part of the South Australian Exploration Initiative. Greenschist to low amphibolite...

Micropalaeontological and biostratigraphic studies have been used. Groundwater flow systems were investigated near the Woolpunda Groundwater Interception Scheme (WGIS) - a major area of saline groundwater discharge to the Murray River. Structure was...

4 samples of drill core from a groundwater investigation well located approximately 6.5 km north-west of Mundulla were examined palaentologically to evaluate whether the Tertiary Murray Basin sediments that were cored can be correlated with similar...

Limestone in which a rare fossil whale tooth had been found was dated.
