The following Tertiary units were identified : Kongorong Fm, Narrawaturk Fm, Buccleuch Fm, Ettrick Fm, Mannum Fm, Kalibar Limestone, Parilla Sand and North West Bend Fm. All of these units are separated by unconformities. Erosional surfaces,...

A multi-commodity mineral exploration programme carried out over an area between Mannum and Strathalbyn, seeking buried targets concealed in Tertiary sediments and basement rocks, comprised aerial magnetic, radiometric and EM surveys; groundwater,...

In the stratigraphic sequence penetrated by Canopus Bore No. 1, five formations are present. From the surface to a depth of 185 feet, the boring passed through Recent surface sand and kunkar followed by medium to coarse sands of Plio-Pleistocene age....

Excavation for the pumping station at Mannum exposed a mid-Tertiary sequence of calcareous sandstones and clays with an abrupt change in sedimentation within the sequence. Three marine formations are recognized: the Mannum Formation, the Finniss Clays...

Remnants of transgressive mid-Tertiary limestones occur at 413 feet above sea level (513 above datum level Port Adelaide, relative to bench mark 20/A, Truro R.S.) in and to the north of Levi's Creek, Section 229E, Hundred of Anna, and on Section 26,...

The report describes the progress made to September 1st 1960 of a survey of stone deposits within a 50 mile radius of the Chowilla Damsite. It is concluded that only shallow deposits of variable quality will be available within 30 miles of the site...

Five stratigraphic bores at Chowilla Dam Site intersected Post-Tertiary river sands and silts, equivalents of the Loxton Sands grading downwards into highly glauconitic siltstone of the Bookpurnong Beds and, in two bores, Shelly glauconitic marls,...

Two bores on the west bank of the River Murray in the Hundred of Finniss intersected part of the Mannum Formation and the Ettrick Formation before entering weathered granite. Site 5, Bore 1, 2 miles east of Mannum had the lower part of the Mannum and...

The site of a proposed silo at Geranium was investigated by means of two cable tool holes up to 20m deep. The drilling showed a sequence of Holocene clays and sandy clays overlying Pliocene Loxton-Parilla Sand at 4-6m depth. Hole 1 intersected the...

At a meeting of the Chowilla Dam Technical Committee on 9th November, it was requested that the Mines Department prepare a progress statement on the investigations being carried out for the location and proving of rip-rap sources. This report was...

Bundy No. 1 well near the eastern margin of the Murray Basin intersected a sequence 1340 feet thick of non marine lignitic sands and silts of Tertiary age. The oldest are Eocene and the youngest probably Pliocene. The well bottomed in granite at 1340...

Three potential damsites on the lower Murray River near Mannum were investigated by drilling and geological mapping. Two holes at Site 4 and one at Site 5 showed Tertiary sediments overlying granite bedrock at depth exceeding 24m. Exploration was...

Six bores on the eastern bank of the River Murray at the Teal Flat Damsite in the Hundred of Younghusband intersected post Miocene sediments before bottoming in weathered Kanmantoo bedrock. A seventh bore intersected typical Mannum Formation limestone...

In a reconnaissance survey for sedimentary phosphate, sludges and cores were examined from 100 widely-scattered bores in parts of the Murray Basin and the Gambier Embayment of the Otway Basin that are located in South Australia. Microscopic inspection...

A review is given of the progress of a SADM investigation into the causes of drainage problems being experienced in some South Australian irrigation areas located along the River Murray. Drilling and geological survey work have been carried out over...

A survey has been undertaken to determine the areal extent and variation in thickness of impermeable clay strata underlying the Greenways Irrigation Scheme at Nildottie. Thick clay was found on the eastern half of the Scheme underlying, in general,...

The survey was made to determine the extent and variation in thickness of impermeable clay strata under an area proposed for irrigation development. The area was proved to be free of clay except for an insignificant zone on the western boundary of...

Stratigraphic data are provided for: Waikerie Pumping Station - cliff section, Waikerie Bore No. 1, Waikerie Bore No. 1A, Ramco Heights Bore No. 1, Sunlands Pumping Station - cliff section, Sunlands Bore No. 2 and Tolleys Rising Main section (all in...
