Samples examined from two engineering boreholes indicate that they penetrated Blanche Point Formation and probably also the South Maslin Sand Member of the Maslin Sands.

The Willunga Embayment of the St. Vincent Basin is one of the classic areas of Cainozoic geology in South Australia with published studies dating back over the past century. This present study reassesses the geology of the Middle Eocene to Early...

Investigations in the Myponga Basin have shown that there is no direct evidence for groundwater depletion. Currently there are 45 irrigation wells pumping from an unconfined/confined limestone aquifer. The potentiometric surface drops 5-6 metres...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

Activities from 1986 to August 1988 included the compilation of a borehole data base, the setting up of a new monitoring network, drilling, test pumping, geophysical logging of wells, water sampling, and a land use survey. Transmissivities from test...

The Willunga Basin is a groundwater resource being stressed by groundwater abstraction for agricultural purposes. The Southern Vales Water Resources Committee, in conjunction with MESA, DENR and SA WATER, are developing groundwater management...

MESA has been approached by civil engineering firm B.C. Tonkin and Associates to help with assessing the possibility of developing an aquifer storage and recovery scheme in the Adelaide South Parklands. Their client the Adelaide City Council is...

The importance of engineering geology has been emphasised since the 1950s. when construction commenced in the city of a new generation of multistorey buildings. Foundation drilling along with geological and geophysical services provided by the...

Beach Petroleum Black Point No. 1 Stratigraphic Well intersected 574 feet of mostly recent and lower Tertiary sediments before entering lower to middle Cambrian red-bed arkrose of an unnamed formation which has been mapped at Pint Point and Rocky...

Grange No. 1 Well was drilled to a depth of 1983 feet, and penetrated a sedimentary sequence of Quaternary and Tertiary rocks to 1872 feet before bottoming in red shale and grey slates of Proterozoic Age. Pleistocene to Recent sandy clays with some...

Beach Petroleum Troubridge Shoal No. 1 Stratigraphic Well, drilled to a depth of 1600 feet intersected Recent, Subrecent and Tertiary sediments to 850 feet below which 750 feet of Lower Permian glacial marine rocks were intersected. The Tertiary...

McLaren Vale, one of South Australia's major wine producing regions, is nestled in a geological province known as the Willunga Embayment, just a short drive south of Adelaide. From the sediments which were deposited in the basin-shaped embayment,...

Excavation for the proposed campus extensions will be mainly in mottled clays (Hindmarsh Clays). Hallett Cove Sandstone formation will be exposed towards the base of the excavation. The Hallett Cove Sandstone Formation varies from a very weak to...

Investigation of the foundation conditions for a bridge over the Onkaparinga River at Noarlunga was requested in a letter dated 25th October, 1966, from the Commissioner of Highways. Geological mapping and drilling was requested. Previous auger...

Examination of eleven bores representing hundreds of Dublin, Port Gawler, Munno Para, and Yatala, permits a more comprehensive synthesis of the stratigraphy and micropalaeontology of the Adelaide Plains Cainozoic sequence than hitherto possible. Of...

Further drilling to determine foundation conditions at the proposed Waymouth Street Telephone Exchange was requested in a letter from the Director of Works dated 5th February. It was requested that this work be carried out in liaison with Soilmech Pty...

The geological conditions and rock and soil properties existing beneath the Adelaide city area, have, of necessity, become more important as both the size of buildings, and the extent of construct ion has increased. Drilling and excavation in the area...
