312 metres of Cainozoic overlie Precambrian bedrock : ABC Range Quartzite (312-587 metres) conformably overlying finer-grained Brachina Formation (587-682 metres). The drilling and former seismic data permitted reinterpretation of bedrock structure...

At the request of the Department of Marine and Harbours a seismic refraction survey was conducted at the Porter Bay Marina site, Port Lincoln to investigate the possible presence of ?granitic boulders within the sedimentary sequence beneath areas of...

The Barabba Gravity Low in the Northern Adelaide Plains has been interpreted as a southerly dipping trough-like depression in Precambrian bedrock, infilled with Tertiary and covered by a blanket of Quaternary sediments. All margins of this feature are...

Geophysical and geological surveys and drilling in the Northern Adelaide Plains of South Australia have located a Tertiary palaeochannel incised within Proterozoic bedrock. Present data indicate favourable reservoir and seal conditions for the...

Shallow refraction seismic work was carried out over the site of the oval at the proposed Coromandel Valley South Primary School. The aim of the survey was to assess the rippability of the material that will be excavated. Seismic results show that...

A series of experimental radial seismic refraction spreads were designed for use in measuring the velocity of near-surface limestone at a borrow pit near Dublin, with the aim of deducing rippability of the calcrete. Results show a zone within the pit...

Hammer refraction seismic testing near some bridge sites in the Northeast Transit corridor delineated mainly the water table and not the different layers of rock. To obtain the hard bedrock - water bearing sediments interface a much larger spread and...

Shallow refraction seismic work was carried out in the vicinity of the proposed water filtration plant at Happy Valley Reservoir. This indicated that there would be a little difficulty in excavating material to the level desired using a D8 or D9...

In 1981, SADME hydrological bore Walloway 1 intersected 23 metres of Eocene coal at a depth of 244 metres. Available geological and geophysical data have been reviewed to assess the basin's prospectivity for Tertiary coal.

A shallow refraction seismic survey was conducted along the causeway adjacent to the boat channel at St. Kilda, during its exposure at low tide. The aim of the survey was to determine the thickness of the St. Kilda Formation consisting of shelly sand,...

A shallow seismic refraction survey was carried out around the disposal lagoons at the Naracoorte Saleyards to determine the depth to the underlying Gambier Limestone bedrock. If the floors to existing effluent disposal lagoon excavations are near...

At the request of the Highways Department, a shallow refraction seismic survey was carried out near Riverton to test the rippability of thin massive dolomite and siltstone bands striking approximately 10°E and dipping approximately 30°E. The survey...

SADME and exploration companies have carried out magnetic, gravity, and seismic surveys in the basin since 1961. Areas of significant sedimentary thicknesses have been found in troughs which contain rocks of Permian, Devonian, and Cambrian age below...

A geological and geophysical investigation was carried out at a proposed site for hospital extensions to check foundation conditions. Interpreted depth to weathered bedrock ranged from 2 to 3 m along two seismic lines. The fill material above bedrock...

A seismic refraction survey and two cable tool drill holes were completed to determine foundation conditions for a proposed drainage structure at Dry Crek, Monarto. Drilling showed 10m of Quaternary alluvium overlying Cambrian Kanmantoo Group schist...

A seismic survey was carried out at the site proposed for the new Hackham High School to determine rippability and foundation conditions. Results indicate that lower velocity material lies between calcreted near-surface layers and weathered basement....

A shallow seismic refraction survey was carried out around the effluent disposal lagoons at Naracoorte Abattoir to determine the depth to the top of the Gambier Limestone. This unit was found to subcrop at a depth of approximately 13 m over most of...

This outline was compiled from available seismic and drilling data. Renewed exploration activity has shown the need to upgrade information relating to the Permian and the ?Cambrian sub-basins beneath. 2 seismic programmes, to clarify the structural...

Model has been constructed from magnetic, gravity and seismic data from EL 370 (Aquitaine and Delhi), of a shallow horst of granitoid basement in the southeast of Yadlamalka 1:50 000 area, and, under the lake, a basin, up to 4 500 metres of dense...
