An absolute age of 677 Ma +/- 12 Ma was determined from analyses of six selected zircon grains separated from the subject volcanic rock sample, but the result is strongly affected by the need to impose large corrections to the data to compensate for...

348 reconnaisance air-core drillholes were completed on the subject ELs between 5 July and 3 October 1990. The best heavy mineral sand intersections were found near Immarna (EL 1602), with some zones approaching ore-grade percentages. Unfortunately,...

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...

Brief inspection of uranium occurrences at the East Painter, Shamrock and Commonwealth Mines were carried out during August, 1957. A corundum-monazite occurrence was also visited. Recommendations for further work are made.

During drilling of construction sand and clay in 1976 and 1977, an accumulation of heavy minerals was discovered in an embayment on the eastern margin of the Tertiary basin. Heavy minerals, mainly ilmenite, rutile,and zircon, with lesser amounts of...

The Cainozoic Eucla Basin has been the focus of recent heavy mineral exploration due to the recognition of Tertiary coastal features including the Ooldea Range. Hypsometric and Landsat data, together with detailed work on the Tertiary stratigraphy of...

The 2 sands are similar in major constituents but differ in rare trace constituents, in grain size and in state of oxidation. They are probably different parts of the same unit.

Exploration of an onshore area located in the vicinity of Watraba aimed to discover beach or shallow marine placer concentrations of zircon-rich heavy mineral sands, possibly formed within significant thicknesses of prospective Upper Tertiary Ooldea...

[ Note - here is only Part 1 of an abstract relating to 2 separately indexed parts ]. The subject two areas covering the northern outcropping Peake and Denison Ranges basement inliers were taken up by Pancontinental Mining to test for possible...

An area situated immediately south-east of Elliston has been explored for diamonds, in conjunction with similar work being carried out by the joint venture on Flinders Island and on its adjoining Venus Bay, Colton and Polda mineral exploration...

Through the financial assistance of PIRSA's PACE Initiative, Iluka Resources was able to undertake exploratory drilling activities looking for heavy mineral (HM) sands marine placer deposits in the eastern Eucla Basin, as part of the Year 4 subsidy...

The original objectives of this project were: 1) To understand the processes responsible for transporting, concentrating and fixing copper and other ore constituents during sedimentary basin evolution 2) To document the various stages and paragenesis...

As a result of PACE Initiative - subsidised regional exploratory drilling for Tertiary heavy mineral sands carried out on the north-western Eyre Peninsula during February-April 2006, comprising 349 aircore drillholes put down along 19 traverses for a...
