Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The King Leopold and Halls Creek Orogens in the Kimberley region of northern Australia are divided into three distinct terranes, each representing a different tectonic setting, that may be part of a larger, diverse collisional orogen on a scale similar to the present Alpine-Himalayan Orogen. Collision with the Kimberley Craton drove intracratonic deformation in the adjacent Tanami and Arunta regions of the North Australian Craton. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Geoscience Australia provides information on the nation's future capacity to produce mineral resources. Australia's Identified Mineral Resources is an annual nation-wide assessment of Australia's ore reserves and mineral resources. All major and a number of minor mineral commodities mined in Australia are assessed. Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2005 - bauxite, cobalt, diamond (gem and industrial), iron ore, manganese, nickel, rutile, silver, uranium, zinc and zircon. EDR of black coal, copper, gold and tantalum decreased in the same period. EDR for brown coal, magnesite, molybdenum, niobium, platinum group metals, shale oil, and vanadium remained at levels similar to those reported in 2005. Increases in EDR were due to on-going drilling and evaluation of known deposits resulting in the transfer (re-assessment) of resources from inferred or sub-economic categories into EDR, and discoveries of new deposits or extensions of known deposits. A few mining companies re-estimated ore reserves and mineral resources more conservatively, notably in regard to black coal, to comply with the requirements of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code).

This report describes the investigations into the coastal creek system conducted within the Fitzroy agricultural contaminants project. Before this work started there had been only a limited data acquisition on the water quality parameters in several of the coastal creeks carried out by the Queensland Environmental Protection Agency (EPA). These data are a valuable augmentation to the data collected under Coastal CRC auspices. We briefly outline the consolidated dataset, draw qualitative conclusions from it, and develop a conceptual model reflecting the interacting processes. These analyses are then the starting point for the development of a quantitative characterisation of the role of the coastal creeks in the biogeochemistry of Keppel Bay.

In this study of the beach-ridge plain at Keppel Bay, on the central coast of Queensland, we examine ridge morphology, sediment texture and geochemistry. We build a detailed chronology for the ridge succession using the optically stimulated luminescence (OSL) dating method. Although our interpretations are preliminary, our results suggest that significant changes have occurred in the rate of shoreline accumulation of sediment, catchment sediment source areas, and that there have been minor falls in relative sea level.

The central aim of the Comparative Geomorphology of Estuaries Project of the Coastal CRC was to improve our understanding of Australia's near-pristine estuaries. As the title implies, the project had a geomorphic focus in that a major output was mapping of geomorphic habitats of a representative selection of nearpristine estuaries from around Australia.

Australia's near-pristine estuaries are some of our most valuable natural assets, with many natural and cultural heritage values. They are important as undisturbed habitat for native plants and animals, for biodiversity conservation, as Indigenous lands and for tourism. They also support near-shore fisheries. In addition, by studying near-pristine estuaries, scientists can learn more about the way humans have changed natural systems. This information then feeds into natural resource management because it constitutes benchmark or baseline information against which similar information from more modified estuaries can be compared.

Australian mineral exploration spending in 2004-05 rose by 31% to $1028.3 million of which 39.3% was spent on the search for new deposits. Total global non-ferrous mineral exploration budgets rose 38% to an estimated US$5.1 billion in 2005. Western Australia received 59% of Australian mineral exploration spending in 2004-05 as spending rose in all States except Victoria. Gold remained the main target but its share of spending was eroded by increased spending on nickel, copper, iron ore, coal and uranium. Exploration resulted in significant increases in resources at known deposits and a substantial number of drill intersections of economic interest, the most notable being the discoveries of copper-gold mineralisation at Carrapateena (Gawler Craton), mineral sand in the Eucla Basin, and gold at the Trident deposit (Yilgarn Craton).
