Several anomalous radioactive areas were located and uranium mineralisation shown to be in association with five of them. These areas require further investigation by geological mapping to determine whether or not there are possibilities of economic...

A ground scintillometer survey was carried out at the request of the Senior Geologist (Uranium & Fuel Section) on M.E. Varischetti’s prospect, near Bimbowrie. Although uranium mineralization had been located in an abandoned open-cut, the survey...

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...

Excavation of three backhoe pits has confirmed the presence of calcreted bedrock at an average depth of 0.3 m beneath the site. It is considered that this will provide a suitable bearing horizon. Rotary drilling, based on results of a gravity survey,...

A proposed Primary School will be constructed on thinly covered limestone in an area near caves and sinkholes. To avoid siting buildings on collapsible areas, a 601 station gravity survey was conducted on a 5 m grid. No near-surface voids were...

Bumbarlow 1 (TD 720.33 m) aimed to test the lithology and petroleum potential of the Cambrian section in the central part of the eastern Arrowie Basin. It continuously cored a sequence over 300 m thick of flat-lying Proterozoic sediments interbedded...

An interpretation of the results of detailed gravity surveys and of drilling data obtained from stratigraphic drillholes Tickera DDH 1 and 2 and Wokurna DDH 1 - 3 indicates that basement consisting of metamorphic rocks subcrops shallowly west of the...

A cheap EHT circuit has been designed and built by the Geophysical Technical Services Section of the South Australian Department of Mines and Energy for use in downhole radiometric probes. Spare circuits are carried with logging units to reduce down...

Between February and July 1979, six deep regional investigation holes and thirteen shallow local investigation holes were drilled in the Upper Murraylands area of South Australia. ATS values range from 7000 to 25,000 mg/1 within the Morgan/Mannum...

Report summarises drilling and geology. Regional drilling programme included rotary drilling near Lock coal deposit. Only P21 intersected coal.

Aim was 1) to determine whether Permian sediments extended across the northern Muloorina Ridge, and thereby connected the Arckaringa and Pedirka basins; 2) to identify basement high-speed seismic refractor. The well was abandoned in Early Cretaceous...

Geophysical and geological surveys plus test drilling have located a Tertiary palaeochannel incised within Cambrian-Precambrian bedrock. Present data indicate potentially favourable reservoir and seal conditions, although its headward extent and...

Fractured rock aquifers were investigated by drilling of 7 vertical holes and 2 angle holes in the Windy Creek area. 1 well was completed as production well with an airlift yield of 12 L/s. The steeply dipping fractured sandstone aquifer responds as a...

Groundwater is suitable only for dust suppression or other industrial uses.

Experimental seismic work was carried out to delineate an infilled glacial valley development as a safe harbour. Both conventional in-line shallow refraction and broadside shooting were used to obtain a complete profile of the valley. Test excavation...

Water budget and salt balance studies indicate deterioration in water quality with time since there is now no natural outflow for the confined groundwater. A controlled well recharge experiment using water from Lake Alexandrina with 2 injection and 3...

Investigation of pollution from waste disposal sites in present and future reclaimed Cainozoic sand quarries, includes evaluation of all data and rotary drilling of 30 holes.

The well was drilled to investigate stratigraphy and hydrogeology of Tertiary formations. The Tertiary aquifers intersected contain groundwater of high salinity. 8 metres of Munno Para Clay separating aquifers A and B were intersected. The well was...

The experiments indicate conglomerate can be delineated by seismic methods in both natural surface and removed overburden situations. However, confirmation by test drilling is needed. Some modifications to the original method are recommended along...

The fully rotary cored Oakvale 1 vertical stratigraphic drillhole was drilled by SADME Regional Geology Branch, 13 km east of Oakvale Station homestead in the north of the Murray Basin within SA, over the period 22/5/1981 to 10/6/1981. The hole was...
