As a result of investigations the location for a trial bore has been chosen. Meanwhile, background studies continue over a wide area in the Keith district to provide confirmation for the conclusions already reached.

At Up-and-Down Rocks the Gambier Limestone has been irregularly dolomitised. The deposit supplies about 10 000 tons of dolomite a year for the manufacture of sheet glass. It is pale brown to pink, and varies from very hard rock to loose sand; all...

On 17th January, 1968, the E. & W.S. Department requested an investigation to ascertain the best location for additional bores to augment supplies to consumers in Bordertown, The supply is obtained at present from three boreholes fitted with pumps...

Foraminifera and stratigraphy of four water bores in the Hundred of Stirling and one bore in the Hundred of Laffer have been examined. The total thickness of the Cainozoic sequence to bedrock, proved in two bores, varies from 398 feet near Emu Flat, 4...

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....

The construction of a stone-mound breakwater at Fort MacDonnell will require about 100,000 to 170,000-tons of suitable stone. Individual blocks should be about 5 tons in weight, and an amount as yet unspecified should contain individual blocks which...

A subsidence appeared over a suspected solution cavity at the Glencoe West Oval in August, 1971. A detailed gravity survey conducted over the oval showed anomalously negative values in the vicinity of the subsidence. A small gravity high in the centre...

In 1969, a program of hydrogeological investigation was carried out in Test Area 1 as part of the South East Water Resources Investigation. The results were described in a report by Harris (1969). Since that time there has been:- (a) a monitoring...

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...

The most significant feature of the area, covered by the Naracoorte 1:250 000 sheet is the Padthaway Ridge which underlies all but the southernmost part of the area, where Mesozoic sediments, of the Otway Basin lap onto the ridge (Padthaway...

Following discussion between this Department's Resident Geologist at Naracoorte and the E. & W.S. Department's Regional Engineer, Southern, a request was received from the latter Department in a letter dated 12th July, 1971, to sink and pump test...
