Large sedimentary phosphorate deposits are unlikely to be found in the Cambrian on Fleurieu Peninsula or the southern part of Yorke Peninsula. Further exploration of the phosphatic Brighton Limestone and Saddleworth Formation type of facies should be...

The area covered in this survey comprises about 100 square miles. The main rivers are the Angas and Bremer, the major townships Strathalbyn and Langhorne Creek. There is a marked population concentration adjacent to the rivers, due possibly to the...

The results of the shallow seismic refraction survey indicate that the majority of the material required to be removed is marginally rippable by the the newer, larger machine intended for purchase, having a velocity ranging between 3200 to 9500 feet...

This report summarizes the outcropping rock types and structure present on the Vennachar and Borda 1:50,000 mapsheet areas on the western end of Kangaroo Island. The sheets cover most of Flinders Chase, which is a flora and fauna reserve. The oldest...

The most significant feature of the area, covered by the Naracoorte 1:250 000 sheet is the Padthaway Ridge which underlies all but the southernmost part of the area, where Mesozoic sediments, of the Otway Basin lap onto the ridge (Padthaway...

Over the site proposed for an artificial lake in the area for which the new city of Monarto is planned seismic refraction traverses were used in an attempt to check bedrock conditions. Shooting conditions were very difficult over most of the area as...

Results of two diamond drill holes, a seismic survey and one cable tool hole, indicate that this valley site is suitable for an arch dam, or a mass concrete or rockfill dam. A grout curtain will be necesary. A glacial channel on the right abutment...

Mannum Limestone outcrops along 300m on the left bank of a proposed artificial lake at Rocky Gully, Monarto. A seismic refraction survey and eight rotary drill holes tested the extent of the limestone and the possibility of leakage from the lake. The...

Continuing previous work (Nelson, 1973) the author made a number of seismic refraction traverses over proposed road cuttings on the South Eastern freeway. Most cuttings should require blasting in parts to loosen rock material. However, where extensive...

Seismic refraction traverses along the right abutment ridge of a proposed dam in Hindmarsh Valley were used to predict depth to Cambrian bedrock. The results indicated that the bedrock core of the abutment ridge falls in some places below the full...
