The purpose of the work described was to compare and contrast the petrography, accessory minerals, and absolute ages of 25 granitic and allied rock samples collected from widely scattered localities in South Australia. The processes that are...

Mapping of the Wooltana Volcanic Belt in the northern Flinders Ranges of South Australia has shown that 2000 feet of Willouran trachytic lavas, with minor andesites and rhyolites, outcrop along the southern margin of the Mount Painter complex and...

A new pumping station is to be built in the Blue Lake crater to supply Mount Gambier with water. Access to this pumping station by a tunnel from the bottom of an old pumping shaft is proposed. The new pumping station is to be built adjacent to the...

Bumbarlow 1 (TD 720.33 m) aimed to test the lithology and petroleum potential of the Cambrian section in the central part of the eastern Arrowie Basin. It continuously cored a sequence over 300 m thick of flat-lying Proterozoic sediments interbedded...

Aggregate for sealing the Stuart Highway will be required to be sourced from three main areas (localities a-c below) in addition to the existing quarry at Woocalla. Within these areas eleven potential sites have been nominated, from which three or...

The Gawler Range Volcanics show only trace amounts of molybdenum, silver and tin. In the Tarcoola area, significant amounts of tin in altered granite near Warna Rock Hole and high silver and lead values at Pinding Rocks are worthy of follow up....

Flow banded, porphyritic acid volcanics (similar in age to the Gawler Range Volcanics) occur on Hart Island. Xenolithic within the volcanics is pink leucogranite, about 1550 Ma. Synchronous with the volcanics are grey, leucocratic alkali granites....

Wilgena 1 (TD 973 m) penetrated 964 m into Tarcoola Formation within the Wilgena Sub-basin, without encountering magnetic basement. Thin dacitic to basaltic tuffs and basaltic flows, interbedded with carbonaceous siltstones, indicate contemporaneous...

Includes a discussion about probable processes of mobilisation and recrystallisation of the dolomitic sediments, and describes the evidence found for the presence of a pyroclastic component in many of the non-carbonate sedimentary rock samples.

Assessment of suitability for age determination by means of uranium lead isotope ratios in zircons. The rocks described include andesite, dacite, trachyte, rhyodacite and rhyolite.

Geological interpretation from drilling and seismic information, on an Early Palaeozoic sedimentary basin containing Early Cambrian to possibly Devonian age rocks. Middle to latest Late Cambrian sediments (Kalladeina Formation) and probable Cambrian...

2 distinct groups of basaltic volcanoes constitute a western extension to the Newer Volcanics of western Victoria. The older Mount Burr Range group include 14 fissure controlled centres with lava flows, composite domes and cones and tuff rings or...

Samples include Permian sandstones (Alpara Formation) similar to Cooper Basin sediments, plus Willouran rocks, possibly Sturtian and Permian tillites and one (?)pre-Willouran granitoid.

Processes suitable for use by small scale mining operations are discussed in detail. Covers methods of treatment for oxidized ores, sulphide ores and mixed sulphide oxide ores, marketing and economics.

Gravity traverses completed over the Blinman Dome indicate the presence of a low density body, interpreted to consist of brecciated material with a large depth extent. The bulk of the dismembered sedimentary rafts and xenoliths may be confined within...
