The sites of four cuttings on the Ucolta-Paratoo deviation of the Port Pirie-Cockburn railway were investigated by one diamond drill hole at each site, ranging from 15 to 31m deep. The holes intersected various hard fresh Adelaidean (Burra Group)...

A potential limestone deposit near Yongala, to be used as railway ballast on the Port Pirie-Cockburn railway, was investigated by a stadia survey and the drilling of five diamond holes up to 18m deep. The holes intersected variably weathered...

In South Australia there are a number of limestone occurrences which have been worked for long periods, and a large tonnage of limestone fines has accumulated. These fines are of too low a grade to be used commercially and the Department of Mines...

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...

Deposits of limestone at Mount Gambier have for some time attracted attention as a possible source of lime. The limestone is a soft polyzoal material which can be readily mined and is also of high purity, containing about 97 per cent CaCO3, so that...

This paper deals briefly with the geology and mineralisation of the Ediacara Mineral Field, which is located about 300 miles north of Adelaide in the Mount James Range. The field was discovered some time prior to 1872. Total recorded production for...

This site was examined by Mr. W. Johnson and was the subject of a report by him dated 20 February 1962. In that report Mr. Johnson described and assessed the engineering aspects of the geology on the basis of some test pits and information yielded by...

High grade limestones which outcrop over a distance of some 13 miles along the front of the Flinders Ranges east of Brachina and Parachilna were sampled during the period 5th December 1963 to 16th December 1963 with the assistance of T. Amtmania, W.V....

The foraminiferal faunas of the Upper Eocene and Lower Miocene Limestones of Christmas Island in the Indian Ocean are described. Except for the fringing reefs, no rocks younger than Burdigalian were identified.

In South Australia there are a number of limestone occurrences which have been worked for long periods, and a high tonnage of limestone fines has accumulated. These fines are of too low a grade to be used commercially, and the Department of Mines...

Results of laboratory testing of selected drill core samples, carried out by the Highways and Local Government Department, are presented. Those support an earlier recommendation for trial pits.

Diamond drilling of the deposit has indicated three and a half million cubic yards of limestone overlain by one and a half million cubic yards pf overburden much of which can be utilised in construction. Further investigation of the properties of the...

Three relatively deep bores, drilled recently on the northern Adelaide Plains in the Hundred of Port Gawler, about 20 miles north of Adelaide, have intersected useful complementary sections of the Cainozoic succession, ranging from 560 feet to 1148...

Three samples of alunite containing various amounts of silica were subjected to heat treatment and the residues extracted with water to recover potassium sulphate. High recoveries were obtained from a sample containing only a small percentage of...

Since the days of early settlement in South Australia mineral production from Yorke Peninsula has made an important contribution to the wealth of the state. Firstly, with the discovery and mining of copper in the Moonta Wallaroo district early in...

Exploration of the limestone of the left abutment by mapping, adits and five diamond drill holes has revealed extensive bedding plane faults, shears and shear tension joints. Fracturing and brecciation caused by the fault movements has allowed deep...

Analyses of samples of some Recent and Tertiary limestone deposits on Yorke Peninsula indicate that none of the samples are within the specifications for use in open hearth firing of blast furnaces. The required tonnage could readily be proved, but...
