This report presents the results from zircon LA–ICP–MS U–Pb geochronological age determinations, and both trace and rare earth element abundance geochemical analyses, performed on fifteen outcrop and drill core samples originating from the...

This report presents the results from multi-isotopic apatite and zircon SHRIMP U–Pb geochronology on thirteen samples from the central-western Gawler Craton. Eleven drill core samples are interpreted ultramafic to mafic intrusive rocks, with most...

This Report Book contains zircon U-Pb geochronological data obtained between December 2006 and June 2007, for rock samples derived from the Gawler Craton of South Australia. The geochronological study was undertaken as part of the National Geoscience...

This publication has been compiled from a display prepared for the launch of SADME Bulletin 53, held at the Australian Mineral Foundation on 7 December 1987. The importance and diversity of commodities found in the Geosyncline are highlighted in the...

The geology of the Lake Gilles locale in the south-west of the PORT AUGUSTA 1:250k map sheet area is poorly understood. Outcrop of basement rocks there is sparse, and typically occurs along the margins of the salt lake, where it is highly weathered....

Brief description of sampling procedures and sites. All samples analysed by semi-quantitative spectrographic method for precious and rare earth elements. Results in appendix.

The major units present are Middle Proterozoic leucogranites, alkali granites and porphyries, overlain by Pleistocene Bridgewater Formation. Leucogranites contain up to 10% phenocrysts of potassium feldspar and bluish quartz, alkali granites contain...

The YARDEA 1:250,000 scale regional geological map area straddles the southern margin of the Gawler Ranges on northern Eyre Peninsula. The only major township within the area is Minnipa, with Kimba and Wudinna both located immediately south of the...

The KIMBA 1:250 000 geological map sheet (hereafter referred to as KIMBA) lies in central Eyre Peninsula, extending between latitudes 33° to 34° S and longitudes 135° to 136°30'E (Fig 1). The principal towns are Kimba and Cleve, with smaller towns at...

Mapping and sampling of 39 adits at Mongolata Goldfield has ensured that a permanent record of the 1930s mines is available for historical and exploration purposes. Many of the workings are no longer accessible. Details of the production history of...

Mintabie Opalfield, one of the most important production centres in Australia, was discovered in the early 1920s but mining only began in earnest in 1976. Precious opal is confined to Mintabie beds, a kaolinitic sandstone of presumed Ordovician Age,...

This report book presents the results of seven geochronology research projects completed during 2009 and 2010 as a new part of the ongoing PACE Initiative geoscientific data gathering activity underwritten by the South Australian Government. It has...

The 2010 GOMA basement drilling program formed part of a collaborative ARC Linkage Project LP0882000 " Unearthing the marginal terrains of the South Australian Craton: Keystone of Proterozoic Australia " arranged between Primary Industries and...

The GOMA basement drilling program was named after the Gawler-Officer-Musgrave-Amadeus deep seismic reflection survey line, that was completed in 2008 by Geoscience Australia (GA) as part of its Onshore Energy Security Program. Funding for the seismic...

TARGET: Possible Tertiary marine placer deposits of heavy mineral sands (ilmenite, rutile, zircon) on the south-eastern margin of the Eucla Basin in the Nunjikompita - Hiltaba area, 100 km east of Ceduna. EXPLORATION: A consultants' photogeological...

As part of ongoing base metal exploration of the area surrounding Bute, initial work done after the expiry of EL 248 comprised the completion of one diamond drillhole to TD 411.2 m within Carpentarian basement, targeting a magnetic anomaly thought to...

A suite of intrusives (St Peter Suite - new name) along western Eyre Peninsula displays a wide range in composition, texture and relationships. The features are typical for mingling and mixing of felsic and mafic magmas, with U-Pb geochronology...

An area located 30 km south of Port Augusta and covering more than 792 square km east of the main highway between Port Augusta and Whyalla, which falls entirely within part of the Cultana Army Training Area held by the Australian Commonwealth...

Two separate licence areas located within the greater Waukaringa region north of Yunta in the Adelaide Fold Belt were taken up to explore for possible economic buried gold (both primary and secondary mineral occurrences), and also for any economic...
