A survey has been undertaken to determine the areal extent and variation in thickness of impermeable clay strata underlying the Greenways Irrigation Scheme at Nildottie. Thick clay was found on the eastern half of the Scheme underlying, in general,...

The survey was made to determine the extent and variation in thickness of impermeable clay strata under an area proposed for irrigation development. The area was proved to be free of clay except for an insignificant zone on the western boundary of...

Deposits occur in dunes along margins of gypseous playa lakes, with indicated reserves of 115 000 tonnes, averaging 58% gypsum and inferred reserves of 116 000 tonnes of 50 to 75% gypsum. Grade is suitable for agricultural gypsum usage.

At the Anna Coalfield, the November 1976 appraisal drilling by SADME of 2 rotary mud, partly cored vertical boreholes with a total penetration of 159.62 m (including 28.36 m of continuous ?NQ coring over the coal-bearing section) has confirmed the...

205 auger holes up to 9 metres deep indicate the bulk of the reserves without beneficiation are suitable for agriculture. Reserves of 149 000 tonnes of high grade seed gypsum, suitable for cement and plaster manufacture near present mining...

Flour seed gypsum deposit in lunette dune system was investigated by auger drilling of 34 holes up to 9 metres deep. 243 000 tonnes of flour gypsum remain with an average grade of 43% gypsum, which is unsuitable for commercial use, although...

A recent scout well drilled into the confined Dilwyn Formation (formerly Knight Group) at Mundulla intersected only low permeability sediments unsuitable for development. However, this does not rule out the possibility that a suitable aquifer will be...

Three groundwater observation wells have been drilled at locations north-west of Murray Bridge to determine the effect of increased stream flows down the Rocky Gully and Preamimma Creeks. Rocky Gully Creek will be capable of accepting about 10 000 m...

Cable tool and rotary drilling of 8 holes has enabled the geological sequence and general hydrology to be determined in the area to appraise its potential as a disposal site for stormwater runoff from urbanised Monarto.

A regional groundwater model has been constructed of the Loxton Sands watertable aquifer in the eastern Riverland, over an area extending eastwards from Overland Corner to the State border. It is being used to quantify the salt load impacts on the...

The Loxton-Noora area is underlain by 3 aquifer systems - the Pliocene Sands water table aquifer, the confined Murray Group limestone and the deepest, the confined Renmark Group aquifer. Both confined aquifers contain groundwater of 20-25 000 mg/L...

Following a request from the SA Department of Environment and Natural Resources at Berri in the Riverland, a hydrogeological assessment of the Moorook and New Residence irrigation areas was carried out. The water table aquifer occurs in fine to...

The Murray-Darling Basin Commission (MDBC) has a commitment in the national interest to managing the health of the River Murray and floodplain environment by mitigating both decreases in river water quality and associated environmental degradation...

In an area located west of Waikerie and adjacent to the River Murray, field examination of gypsum bed outcrops and the measuring of strata sections, plus shallow definition drilling (64 holes for a total penetration of 312 m) and backhoe trench...

Four potentially commercial Pleistocene gypsum occurrences located 2.5 km east of Linke's gypsum mining leases, that had previously been outlined by CSR under its lapsed Mineral Claim 2097, were drill-tested by Hooker Resources (46 reverse circulation...

TARGET: Possible Tertiary brown coal deposits near Sedan, in the western Murray Basin. EXPLORATION: Evaluation of data as obtained earlier by SADM/SADME drilling and more recently by subject licensees Thiess/CSR from rotary mud vertical open hole and...
