Materials suitable for concrete aggregate, railway ballast, road base course, protection of salt field sea wails and rock fill will be required should construction of the petrochemical plant and appurtenant works proceed at Redcliff, 25 km...

Regressive intertidal sequences, with well developed zonation of flora and fauna, occur extensively around the margins of the 2 major SA gulfs and within small embayments along the exposed coastline of Eyre Peninsula. This paper summarises and...

Likely excavation conditions during the proposed deepening of the boat channel at St. Kilda were investigated by drilling and seismic refraction surveys. Results showed 2 to 3 m of St. Kilda Formation (loose shelly sand) overlying up to 0.2 m of...

At the request of the Department of Marine and Harbours a seismic refraction survey was conducted at the Porter Bay Marina site, Port Lincoln to investigate the possible presence of ?granitic boulders within the sedimentary sequence beneath areas of...

A water well was drilled on Section 1, Hundred of Adelaide to provide an increased supply of groundwater for Diverse Products Ltd. The well was rotary drilled to a depth of 125 metres and completed open hole in Tertiary limestone. Production testing...

A shallow refraction seismic survey was conducted along the causeway adjacent to the boat channel at St. Kilda, during its exposure at low tide. The aim of the survey was to determine the thickness of the St. Kilda Formation consisting of shelly sand,...

Two exploration wells have been drilled through the Cainozoic sequence to Precambrian bedrock to provide stratigraphic and hydrogeological data. At the South Parklands site two aquifers were tested. The upper one yielded a large supply of marginally...

Eighteen stratigraphic and material testing rotary mud/core drillholes were drilled along King William Street, as part of a feasibility study for an underground railway. All of the holes penetrated the Hindmarsh Clay and the calcareous Hallett Cove...

2 water production wells were completed.

2 holes totalling 144 m intersected Precambrian quartzite at 65 metres. No significant aquifers were found. Geophysical work indicates trough as source of saline ground water and target for coal exploration.

Three observation wells have been completed in the Port Willunga Formation 'A' for the Water Resources Branch of the Engineering and Water Supply Department. These wells are located in the vicinity of the Little Para River to monitor the response of...

Between December 1977 and February 1978, 103 coal exploration and development holes were drilled in the Wakefield and Clinton coal deposits, 100 km north of Adelaide. These Tertiary deposits, in the northern extremity of the St. Vincent Basin, contain...

A seismic refraction survey at Redcliff Point on Spencer Gulf has confirmed the existence of a trough up to 450 m deep and 3.5 km wide, oriented north-south beneath the western portion of the promontory. Two internal refracting horizons have been...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

Drill core from samphire and mangrove marshes north of Gillman - Wingfield are used to interpret the shallow sub-surface stratigraphy of the region. A Holocene marine sequence up to 8 metres thick overlies Late Pleistocene alluvial (Pooraka Formation)...

The sediments exposed in the Bowmans trial pit were mapped and sampled in detail. The oldest formation recognised is the mid to late Eocene Clinton Coal Measures, which is represented by low rank, soft brown coal and unconsolidated, medium grained...

All previous data and all the known major deposits within the Clinton Coal Measures are reviewed. The study covers their formation, structure, stratigraphy and various engineering geology aspects associated with the possibility of mining any one of...

In 1982 ETSA carried out an exploration programme which lead to the discovery of the Lochiel brown coal deposit. Over 10,000 metres of drilling have been completed within the deposit. Reserve and resource calculation and hydrogeological and...

The reasons and procedures for the collection of a 210 tonne bulk sample from the Lochiel coal deposit are outlined, and the geology and hydrogeology are summarised.
