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,...

Kalangdoo Town Water Supply (T.W.S.) No. 1 well was drilled cable tool during February - May, 1977, and subsequently production tested. The unconfined Gambier Limestone aquifer was encountered between 5.5 and 86m, and was later cemented off down to...

The first of a series of high yielding standby wells exploring the confined aquifer was drilled to 208 metres using both rotary and cable tool. Production interval is from 184.6 to 205.3 metres in unconsolidated sands of Dilwyn Formation.

Recent drilling information, aquifer testing, a review of data on existing town water supply wells and a survey of wells intersecting the confined Kongorong Sand aquifer in the vicinity of Kingston have been used to assess the state of Kingston's...

A new town water supply well, Naracoorte no. 10, encountered permeable confined aquifer sands at 160 m depth. Subsequent testing showed the well to have a yield of from 6000 to 7000 cubic m/day at a recommended pump intake depth of 85 m, with less...

More than 400 samples (cuttings and core) from 26 petroleum wells in the South Australian part of the Gambier Basin were examined. Their lithology and foraminiferal fauna were recorded and their age and environment of deposition deduced where...

The sediments of the Gambier Embayment are mainly of Cretaceous and Tertiary age. Lower Cretaceous subsurface units have been referred to outcropping rocks of the Otway and Merino Groups, but satisfactory criteria for their identification with...

The drilled section was subdivided into Cainozoic units. The Gambier - Lacepede contact is probably disconformable. The planktonic foraminiferal sequence in the Lacepede Formation was studied in detail, and important biostratigraphic datums selected....

Stratigraphic evidence indicates major change in sedimentary regime in the Middle Eocene, close to the inferred onset of continental breakup. Deep sea drill core suggests an Antarctic ice sheet may have existed at this time, when Australasia was much...

The bore penetrated Coomandook Formation, Gambier Limestone, Lacepede Formation and Knight Formation including Burrungule Member. The three-part structure of the Gambier Limestone in the Oligocene might be formalized as members, and two zones are...

This report covers the first two stages of a proposed 3-stage pump test on Bore MI-1. Calculations using the Jacob and Theis methods have been used. Good agreement between the various drawdown curves indicates that the values used are reliable for the...

Analyses of pumping tests performed on a semi-confined aquifer of the Knight Group in the Hundred of Mingbool indicate that the coefficient of permeability of the confining bed is approximately 0.015 metres3 day-1 metre-2. Values of transmissivity and...

The development and testing of the Beachport Town Water Supply Bore No. 2, was badly handicapped by incorrect screen selection, an apparently insensitive pressure gauge, and incomplete development of the bore prior to testing. The transmissivity of...

The Beachport Town Water Supply No. 3 was flow-tested using a series of orifice plates. The testing programme consisted of a main test and five stages in a flow recession test. The orifice plates were used not to measure flow rate, but to ensure a...

The Mount Gambier area of south-eastern South Australia is totally dependent upon groundwater for its water supplies. Water of low salinity is extracted from an unconfined aquifer (the Gambier Limestone) and, to a much lesser extent, confined aquifers...

A new well, Kingston No. 10, was drilled on section 504, hundred of Lacepede to augment Kingston's water supply. A flow of water (5 1/sec) was obtained after intersecting Kongorong Sand at 86m. Subsequent well testing showed it to have a safe yield of...

A package of fourteen mineral exploration tenements were taken up that straddled the north-eastern and south-western sides of the Padthaway Ridge, to allow the licensee to explore both the Tertiary Murray Basin and Gambier Basin sediments where they...

A number of portions of licence areas flanking known outcropping uraniferous basement rocks of the Padthaway Ridge have recently been relinquished, after originally being taken up to explore for possible economic sandstone-type uranium deposits that...
