Over the period from 1955 until 1976 an outcrop of Ordovician porphyritic rhyolite was quarried for road-sealing aggregate and rail ballast from two quarries at Mount Monster, 12 km south of Keith. The total recorded production was 548,000 tonnes....

The PORT AUGUSTA 1:250,000 mapsheet area covers the north-eastern part of the Eyre Peninsula, the northern Spencer Gulf and the south-western Flinders Ranges, and extends from latitude 32°00'S to 33°00'S and longitude 136°30'S to 138°00'S. The main...

The Mount Woods Domain (sometimes termed Mount Woods Inlier) is located ~850 km north of Adelaide along the Stuart Highway. The nearest major population centre is Coober Pedy, which lies ~70 km north-west of the northern domain boundary. Geologically,...

Reconnaissance investigations of outcropping rocks of the western and central Mulgathing Complex reveal a series of pelitic and psammitic sedimentary rocks, interleaved with generally mafic to intermediate composition meta-igneous lithologies. The...

The prevailing model of the crustal-scale architecture of the Musgrave Province (Lambeck and Burgess, 1992) proposes a Moho depth offset of 20-25 km beneath the Musgrave Province to explain early teleseismic arrivals and a regional gravity high. This...

Seven samples of Proterozoic basement rocks, representing syn and post-tectonic leucocratic melts that formed during the Kimban Orogeny within the Donington Suite and within cross-cutting Tournefort Metadolerite mafic dykes on the southernmost Eyre...

The subject of this guidebook is the geology of the Eateringinna 1:100 000 sheet and its immediate surrounds. Field sites demonstrate the principal lithology and geological relationships from this part of the eastern the Musgrave Province.

The Boomerang gold prospect is located 650 km north-west of Adelaide in undifferentiated Proterozoic rocks incorporated within Archaean Harris Greenstone Belt mafic lithologies of the Gawler Craton. The prospect was originally discovered using...

This report presents detailed industry-derived statistics on the State's output and sales values of earth resources commodities realised during the six month period ended 31 December 2004, and compares the data with that returned for the previous...

In South Australia, Cambrian massive salt deposits of the eastern Officer Basin occur in troughs lying along the western and north-western margins of the Gawler Craton, and are considered to have been deposited in marginal to open marine environments....

Palynological analyses of samples from Meadows Bore 1 indicate the presence of Late Miocene to Early Pliocene sediments, correlated with the Monotocidites galeatus Zone. At the base of the Tertiary interval examined it appears that a wet rainforest...

High precision geochronological analyses of metamorphic and inherited magmatic zircon grains, which were obtained from stored percussion drillhole samples of a garnet gneiss that occurs within the Commonwealth Hill magnetic anomaly, north-western...

This report presents the results of exploration on the Director of Mines E.L.A. 383 at Sleaford Bay during November, 2006. A number of samples of Carnot Gneiss, Hutchison Group and Donington Suite granitoids were collected from coastal exposures at...

Detailed petrological descriptions of 16 surface and near surface samples of intrusive ?igneous rocks obtained from nine localities spread around Terowie, Eurelia and Bangor have shown that they are intensely altered and weathered, making confirmation...

Gem-quality varieties of beryl occur rarely in South Australia and exist in insufficient quantities to be of current economic interest. Non-gem grade beryl, by contrast, is a widespread accessory mineral in many pegmatites of South Australia, but, at...

Numerous but small uranium prospects occur in the southern Curnamona Province and are described in this report. The source of the uranium mineralisation is related largely to partial melting of originally uranium-enriched Willyama Supergroup...

This report book, the third in the series so far, presents abstracts from the Primary Industries and Resources SA, University of Adelaide and Monash University, ARC Linkage Program also included a one day field excursion to Yorke Peninsula (discussed...

This field guidebook provides brief geological summaries to sites in South Australia that were visited during the 2006 Broken Hill Exploration Initiative pre-conference excursion. Figures show the location of the field area and approximate location of...

The aim of this report is to provide a summary of the present status of the geology of the Olary Domain, Curnamona Province. It gives a comprehensive, referenced description of all known interpretations of Willyama Supergroup basement stratigraphy,...
