New sources of road metal were sought in three areas of the Council district on a basis of regional stratigraphy and structure. On the Willowie Plains, lime-cemented Telford Gravel forms an excellent road surface, and several new sources of this...

This investigation was a feasibility study, therefore environmental factors are dealt with in much more detail than would be necessary in a routine geochemical report. Apparently these factors has little significant effect on the results. Spot...

A government investigation of the economic potential of the abandoned historic Burra Burra copper mine was started in December 1961. The SA Department of Mines (SADM) initial work comprised 1:1200 scale geological mapping of the old mine area,...

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

The Parachilna 1:250 000 map area is about 250 road miles north of Adelaide, South Australia, and includes the eastern shore of Lake Torrens, the central Flinders Ranges and part of the Lake Frome Plains. The ranges are composed of folded Adelaidean...

Despite the palaeoecological emphasis of most recent stromatolite research outside the USSR, controversy still exists regarding the environmental restriction of these organosedimentary structures and in some cases, analogies with modern occurrences...

At South Hill, Willouran Ranges, the lower member of the Skillogalee Dolomite contains new form of Baicalia, B. blastophora. The Wonoka Formation contains an indeterminate form of Linella in the Willouran Ranges and Tungussia inna at Bunyeroo Gorge....

The Spalding inlier is a lens-shaped area of tightly-folded Willouran rocks of the Adelaide System (Upper Precambrian), extending north-south for about 10 miles; it is about 100 miles north of Adelaide. The rim of the inlier is marked in most places...

Two types of stromatolitic boulders occur in a diamictite of possibly Late Precambrian age in north-western Tasmania. The first type comprises dark grey dolomites containing the stromatolite Baicalia cf. B. burra, generally well preserved. The...

The Spalding Inlier, about 150 km north of Adelaide, is the core of a faulted anticlinorium providing a unique exposure of some of the oldest sediments in the southern half of the Adelaide Geosyncline. The discovery of stromatolites within the inlier...

This study reports on a project to establish a magnesium oxide derivatives business in South Australia, by exploiting a resource of sedimentary magnesite held by Commercial Minerals Ltd (a member of the Normandy Poseidon Group of companies). Aspects...

Exploration for possible economic buried gold and/or copper mineralisation that may have formed in a volcanic or porphyry- related setting, within an area of the Adelaide Geosyncline situated 130-140 km north-northeast of Adelaide, has comprised the...

Exploration for possible economic manganese mineralisation of the stratabound type previously found at Ketchowla Hill near Burra, undertaken within a small area located 12 km north-east of Yadlamalka Homestead, has consisted only of a limited field...

Exploration for gold and copper mineralisation within an area located immediately south of Mount Bryan and 19 km north of Burra was aimed principally at finding deposits of copper oxide and carbonate ores similar to those mined historically at Burra...

EL 3972 - Apoinga occurs within the northern Mount Lofty Ranges, where the exposed bedrock comprises Neoproterozoic rocks of the Adelaide Fold Belt. The main feature of interest to Copper Range within its licence area is the Tarnma Anticline, which is...

The only exploration field work completed by JV operator Perilya on the relinquished subareas of the tenement was a review made during 2008 of the magnesite potential of the licence, along with that of EL 3111 (now EL 4211) located adjacent to the...

Copper Range is exploring for copper and other economic stratabound / epigenetic base metals within the Kapunda - Burra copper mineralised structural corridor. The company holds a significant portfolio of exploration licences in the region, which are...

Exploration for copper mineralisation within a small licence area surrounding Mount Tinline, located approximately 20 km south of Spalding ,was aimed principally at finding deposits of oxide and carbonate ores similar to those mined historically at...
