Origin and significance of aromatic hydrocarbons in giant iron ore deposits of the late Archean Hamersley Basin, Western Australia
Late Archean to earliest Paleoproterozoic shales associated with two giant iron ore deposits in the Hamersley Province, Western Australia, contain traces of solvent extractable saturated and aromatic hydrocarbons. The host rocks belong to the 2.5 billion years (Ga) old Mt McRae Shale and Brockman Iron Formation, Hamersley Group, and were collected in mines near Tom Price and Newman (Mt Whalebac...

متن کاملConditions of riebeckite formation in the iron-formation of the Dales Gorge Member, Hamersley Group, Western Australia
Quantitative evaluation of the stability relations of riebeckite, in the system Na-Fe-MgSi-C-GH at low temperature and pressure, is based upon estimated thermodynamic parameters for riebeckite and on chemical and petrologic data. This evaluation forms the basis for an assessment of the conditions of riebeckite formation in the Dales Gorge Member, Hamersley Group, Western Australia. Computed val...
متن کاملModern Subsurface Bacteria in Pristine 2.7 Ga-Old Fossil Stromatolite Drillcore Samples from the Fortescue Group, Western Australia
BACKGROUND Several abiotic processes leading to the formation of life-like signatures or later contamination with actual biogenic traces can blur the interpretation of the earliest fossil record. In recent years, a large body of evidence showing the occurrence of diverse and active microbial communities in the terrestrial subsurface has accumulated. Considering the time elapsed since Archaean s...
متن کاملFinance Industry Restructuring: Implications for Regional Australia
The Australian financial system is undergoing a period of rapid change driven by the introduction of new technologies, changes in regulation and the emergence of new competitive forces. Consumers of financial services are being faced with an array of new products and charges as individual financial institutions respond to these challenges. Some consumers in smaller regional centres have experie...
