Field investigations including drilling and soil gas sampling, carried out as part of a subsurface hazard assessment for a parcel of land at Saint Agnes, did not indicate any significant risks to an intended building development.

The target was gold in Tertiary gravels in the vicinity of the Easter Gift gold mine.

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...

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,...

Albert's Sand Pit Pty. Ltd. is producing sand suitable for construction purposes from the basal Tertiary North Maslin Sands near Maslins Beach. Drilling during 1972 and 1973 has outlined the following reserves of sand under 4.21 million cubic metres...

Most of the sand utilised for civil construction aggregate in the Adelaide Metropolitan area is supplied from the Golden Grove – Highbury basin, the Willunga Basin and the Gawler – Rowland Flat area. The northern rim of the Willunga Basin, east of the...

Auger drilling has been undertaken on behalf of Monier Besser Pty. Ltd. On section 363, Hundred Willunga, to determine the extent of construction sand in this locality. The property adjoins that previously tested (Johns, 1965) and is situated some 31...

Rotary drilling of 16 holes at the Tatachilla sand deposit on the northern margin of the Willunga Basin indicates total reserves of 3.6M cubic metres of construction sand and 0.8M cubic metres of filling sand. Overburden and waste totol 2.3M cubic...

One rotary drill hole 52.5m deep encountered a typical Tertiary sequence of Blanche Point Formation, South Maslin Sand and North Maslin Sand overlying Adelaidean basement. The lower 18m of North Maslin Sand are potentially of construction sand quality.

A borehole survey has been carried out in the Willunga Basin, 30 km south of Adelaide, beginning a new investigation of its hydrogeology. Although the groundwater resources of the Basin are being developed rapidly, there is little useful...
