Following a quotation from this Department to sink a 6 inch water supply bore to a depth of approximately 137 metres (m) at Cowandilla Primary School a letter was received from Public Buildings Department dated 14th February, 1973, requesting the...

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...

A summary of the geology and geomorphology of the Torrens Valley west of the Gorge, has been compiled and the engineering and environmental characteristics of the geological materials present have been assessed. The oldest rocks in the Adelaide area...

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...

The proposed workshop site is underlain by at least 30 m of stiff clay and sand of the Pooraka and Hindmarsh Clay Formations. A surface layer, up to 0.80 m thick, of fill (mostly boiler ash and cinders) overlies the clay. An allowable bearing capacity...

An investigation has been carried out at a possible site for the proposed Northern Power Station. Its purpose has been to provide data for an Environmental Impact Statement. The work has involved geological mapping with drilling and sampling, seismic...

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 PORT AUGUSTA 1:250,000 mapsheet area covers the north-eastern part of the Eyre Peninsula, the northern Spencer Gulf and the south-western Flinders Ranges, and extends from latitude 32°00'S to 33°00'S and longitude 136°30'S to 138°00'S. The main...

This tour is concerned with aspects of the soils, geology, landforms, clays and mining on Yorke Peninsula, and likewise for the northern Adelaide Plains which are separated from the Peninsula by Gulf St Vincent. Both of these regions are among the...

The revised digital geology map of the Cultana 1:100 000 map sheet and accompanying geological descriptions in this report are the first components of the 2nd edition PORT AUGUSTA 1:250 000 map sheet to be completed. The subject map sheet occupies the...

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,...

Hallett Cove is one of South Australia’s foremost natural science treasures. Exposed examples for prime geological concepts of superposition of strata, depositional unconformities (representing time breaks), and folding and faulting of sedimentary...

This project was designed to determine the potential of various clays to absorb harmful or toxic substances present in water intended for human use. The clay samples that were selected for study contain significant amounts of either smectite, kaolin,...

The MAITLAND Special 1:250,000 scale geological map covers the greater part of South Australia's Yorke Peninsula. The rocks in the map area comprise deformed Palaeoproterozoic and early Mesoproterozoic basement of the south-eastern Gawler Craton, and...
