How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Laminated and desiccated siliceous dolostones, dolomitic mudstones and dolomitic sandstones in the Cambrian Parakeelya Alkali Member of the Observatory Hill Formation accumulated in an alkaline playa. Four facies are recognized (from lake centre to lake edge): lake, saline mudflat, dry mudflat and sandflat facies. The facies occur in cycles. Cycles...
The Canning Basin contains several Mississippi Valley‐type Zn‐Pb sulphide prospects and deposits in Devonian carbonate reef complexes on the northern edge of the Fitzroy Trough, and in Ordovician and Silurian marine sequences on the northern margin of the Willara Sub‐basin. This study uses the ionic composition and 5D, δ¹⁸O, δ³⁴S, ⁸⁷Sr/⁸⁶Sr isotopi...
The Canning Basin is a large sedimentary basin with a thick, discontinuous succession of Palaeozoic and Mesozoic marine and continental sedimentary rocks covered by Cainozoic surficial sediments. It contains several Zn-Pb sulphide deposits of Mississippi Valley type. To provide a framework for understanding the mechanism of this mineralisation, a r...
Biomarkers in fluid inclusions can constrain source regimes for hydrocarbons associated with Mississippi Valley-type Pb-Zn deposits. Significant amounts of hydrocarbons have been detected in fluid inclusions in sphalerite and dolomite intimately associated with Pb-Zn sulfides in the Canning Basin, Western Australia. The hydrocarbons are more mature...
Copper mineralization of several different types formed in the Stuart shelf-Adelaide geosyncline region from the middle Proterozoic to the early Paleozoic. Hydrothermal, unconformity-related, and bedded deposits have been distinguished and these are discussed in the light of the geologic evolution of the province. The largest of the copper deposits...
The huge sediment-hosted copper deposits at Olympic Dam and Mount Isa are of unusual types. They formed epigenetically from hydrothermal fluids, as did several other important Australian copper deposits in sedimentary strata. Ore within a palaeoweathering zone at the top of a red-bed unit at Mount Gunson appears to have formed at relatively low tem...
The Myall Creek copper prospect is in unmetamorphosed carbonaceous dolosiltstone and sandstone at the base of the late Proterozoic (Adelaidean) Tapley Hill Formation. It contains disseminated, fine-grained chalcopyrite, zincian tennanite, bornite, chalcocite, pyrite, sphalerite and galena, and irregular to straight chalcopyrite-rich veinlets. Some...
Bedded disseminations. No evidence for hydrothermal alteration. The disseminated sulfides have a delta 34 S range of -17.3 to 15.8 per mil, consistent with bacterial reduction of sulfate. Veinlet sulfides have a similar but smaller delta 34 S range, in accord with formation by remobilization of the disseminated sulfides. No significant delta 13 C d...
