In a continuation of diamond and base metal exploration of newly discovered carbonatite / kimberlite intrusive bodies in an area located immediately north of Orroroo, these bodies were examined petrographically and analysed to compare their...

Twelve million cubic yards of Sturtian slaty limestone may be quarried above the 200 foot level. The stone, which has been tested by the Highways Department, is suitable as crusher run for base courses. The Adelaide system sediments have been folded...

A deposit of limestone situated adjacent to the south bank of the River Onkaparinga, 4 miles NE of Noarlunga, has been tested by diamond drilling to prove its suitability for road building. The good quality of the stone has been confirmed, although...

Detailed geological examination of the area in the vicinity of the proposed tunnel has shown that, provided suitable precautions are taken, there are no geological factors which will prevent the successful construction of a tunnel through the ridge...

Further geological investigations at the dam site, particularly on the left bank, have delineated the width of limestone present and by means of an exploratory adit have shown that solution cavities are relatively rare. Cavities are of two types;...

56 whole rock major and trace element geochemical analyses of Adelaidean and Cambrian sedimentary rock drill core samples recovered from 6 diamond drillholes are presented. Many of the samples are carbonate - rich, and their lithologies include...

The investigation has involved a survey of known wells followed by the drilling of two rotary holes into dolomites of the Tapley Hill Formation. These have been abandoned due to high salinity and low yield. It is considered that the likelihood of...

As part of an ongoing search for extensions to the Cattlegrid orebody style of stratiform Cu-Fe-Mn mineralisation within its exploration licences on the Stuart Shelf, besides testing for any indications of Olympic Dam type Cu-U-Au deposits in the...

An area located within the western Adelaide Fold Belt adjacent to the eastern margin of the Gawler Craton, and centred approximately 20 km south-east of Port Augusta, has been explored for possible economic buried copper mineralisation associated with...

Exploration for copper mineralisation within an area centred immediately north-northeast of Kapunda has as its initial objective to find shallow deposits of oxide and carbonate ores similar to those mined historically at Burra and Kapunda, focussing...

SALT MINING STUDY: Field tests on the feasibility of Lake Torrens salt production to supply raw material for the planned Redcliff Petrochemical Project were continued, with project planning technical data demonstrations given to visiting officials of...

TARGET: Phosphate occurrences in the Mid Sturtian from Port Pirie to Marree. EXPLORATION: Regional investigation of the occurrence, distribution and origin of phosphate by mapping of known phosphate occurrences and geological traversing across...

Mapping of phosphate occurrences in the mid-Sturtian sedimentary sequence of the Adelaide System rocks of South Australia has led to the recognition of 4 types : - bedded phosphorite which generally underlies the Brighton Limestone. This...

A geological consultant's inspection of historic copper mining leases in the Copley district concluded that grid-based soil geochemical sampling, shallow drilling of the oxidised ore zone, trenching to obtain bulk samples for metallurgical tests, and...

This regolith material hand specimen atlas displays 246 images of 212 regolith samples which have been collected over the last 30 years by the authors, present and past Geological Survey of South Australia (GSSA) staff and members of the Cooperative...

Arkosic quartzites of Pre Cambrian age contained in the Torrensian, Sturtian and Marinoan series occur in the Adelaide Hills. The largest deposits are in the Torrension series, in which several alternative quarry sites have been located. Adequate...
