The Onkaparinga River, the largest watercourse draining the Mount Lofty Ranges from the east, south-east and south of Adelaide, already provides water for two reservoirs supplying the Metropolitan Area of Adelaide. These are Happy Valley Reservoir...

The area covered by the Gawler 1 inch to 1 mile Military Sheet, (Scale 1/63,360), has been mapped by B.Campana during the years 1951-1952. Complementary field and laboratory work has been carried out in the metamorphic and granitic terrains by A.W....

Following a request for a geological survey of private property situated in Hundred Yatala, Sections 5451 and 5445 to aid in the determination of its quarry potential, a survey was initiated on September 26th and completed on October 19th, 1960....

A serious breach of Section 17 of the Mines and Works Inspection Act 1920-1962, i.e. the employment of an under-age male person in underground working, was the subject of a complaint which was later verified at the Gumeracha Talc Mine owned by John...

Four road metal quarries have been mapped in detail. Reserves have been calculated and bulldozer cuts recommended to prove the thickness and attitude of the quartzites. The quartzites have not been evaluated as a source of aggregate for use in civil...

A geological investigation of a deposit of Stonyfell Quartzite has been carried out. One subunit appears to be a suitable source of civil engineering construction aggregate. An area in which quarrying could be commenced is suggested.

A quartzite bed outcropping in section 593, Hundred Alma is part of a persistent horizon extending through this section to the north and to the south. Reserves within the area mapped exceed 100,000 yards. Diamond drilling is recommended to test the...

One diamond drill hole was drilled to a depth of 140 feet. The best quality stone occurs between 30 and 129 feet. Reserves in excess of 100,000 yards have been proved. Core recovery from the hole was nearly 66% and is thought to indicate that the...

Rock types mapped in the above area include arkosic ortho quartzites, arkosic sandstones and chloritic quartzite schists of the Stonyfell Quartzite formation in the Torrensian Series. Total available reserves of rock are estimated at over thirty...

Quartzites, sandstones, phyllitic slates and quartz arkeritic dolomite belonging to the Stonyfell Quartzite and “upper phyllites” formations of the Torrensian series in the Adelaide System rocks occur in the above sections. Quartzite and sandstone...

In the first years of settlement Adelaide's water supply was obtained directly from the River Torrens, or from shallow wells along its banks. This water became brackish in summer and caused serious health problems due to pollution. In any case the...

A water supply well was completed at a depth of 110 m in a fractured sandstone aquifer. in Cle.land Conservation Park. Aquifer tests revealed that turbulent flow in joints and fractures predominated over laminar flow with increasing pumping rate....

The diamond and base metal potential is appraised based on recent company exploration for gold and diamond bearing kimberlites, with special reference to regional stratigraphy, tectonic structures based on the Echunga detailed low level aeromagnetic...
