Drilling for construction sand near the northern margin of the Willunga Basin intersected the Eocene succession unconformably overlain by Quaternary units. Two of three holes penetrated into the target North Maslin Sand, but were abandoned before...

Drilling of one cable tool hole has revealed a uniform horizontal succession of unconsolidated sediments which correlate well with previous drilling on the adjacent Chest Clinic site. The strata consist of: Topsoil (0-2m) - 1.5 to 2m of moderately...

Immediately beneath the Elizabeth West waste disposal area, between depths of 6m and at least 128m, is a series of Pleistocene and Tertiary confined aquifers. A site visit and examination of departmental records has indicated that: • The area is one...

Three cable tool holes have been drilled to investigate the foundation conditions for a proposed new bridge over the railway line, on Burbridge Road, Hilton. Drilling disclosed a near horizontal sequence of Quaternary and Tertiary sediments which are...

Newly compiled surface geological mapping data for the Adelaide City and inner eastern suburbs is presented as a draft map and explanatory notes. The distributions of Eocene to Holocene units of the St Vincent Basin have been reinterpreted from...

The availability of good quality groundwater from two Tertiary confined aquifers (T1 and T2) under the Northern Adelaide Plains (NAP) has encouraged the development of over 3000 hectares of horticulture in the area since the 1950s. At present,...

The aim of the present investigation was to determine the hydraulic properties of the Tertiary T2 aquifer and the leakage properties of the overlying confining bed of the Port Willunga Formation. A pump test, involving four production wells and one...
