Northern Territory/Australia

The Australian Ecstasy and Related Drugs reporting system (ERDS), which is based on interviews with regular ecstasy users, seems to confirm these results. The proportion of regular ecstasy users consuming more than a tablet per event declined in 2006 in New South Wales (from 84 per cent in 2004 to 70 per cent in 2006) and in Queensland (from 76 per cent in 2005 to 63 per cent in 2006), the two main ecstasy markets of the country. In Western Australia, South Australia, Northern Territory and Tasmania the opposite trends were observed. Therefore, in 2006, ecstasy use trends, among regular ecstasy users, appear to have stabilized for Australia on the whole. The median number of days ecstasy...

Exploration for unconformity-related deposits is based firstly on Proterozoic red-bed basins overlying basement complexes and source regions characterized by high U contents. Given this criteria alone, there are nearly 200 basins that would qualify. Graphitic metasedimentary units within the basement complex are desirable, but not necessary, as exemplified by the Nabarlek deposit in the Northern Territory, Australia (Polite et al. 2004). Repeated brittle reactivations of ductile structures, normally from far field tectonic events, that may offset the basal unconformity and were foci for fluid flow are required.

Abstract world class unconformity-related U deposits occur in the Proterozoic McArthur Basin (Northern Territory, Australia) and Athabasca Basin (Saskatchewan, Canada). Widespread pre-to post-ore silicifications in the vicinity of the deposits, allow proper observation of paragenetically well-characterized fluid inclusions. We used a combination of microthermometry, Raman microspectroscopy and Laser Induced Breakdown Spectroscopy (LIBS), to establish the physical-chemical characteristics of the main fluids having circulated at the time of U mineralization. The deduced salinities, cation ratios (Na/Ca, Na/Mg) and P-T conditions, led to the detailed characterization of a NaCI-rich brine, a CaCl2-rich brine and a low-salinity fluid, and to the identification of mixing processes that appear to be key factors for U mineralization. 

Unconformity-related U deposits account for more than 33% of the world uranium resource due to their tremendous grade and tonnage. Most of them occur in the McArthur Basin (Northern Territory, Australia) and in the Athabasca Basin (Saskatchewan, Canada). The ore is commonly found close to the interface between Archaean to lower Proterozoic metamorphic and plutonic rocks, and unconformably overlying Proterozoic sandstones. Basement-rooted graphitic reverse faults are also important structural controls.

The Koongarra U deposit in the Northern Territory of Australia has been studied to evaluate the processes and mechanisms involved in the geochemical alteration of the primary ore zone, and to model the formation of the secondary U ore zone and dispersion fan (Duerden 1991 Duerden Airey 1994). Studies of the distribution of the U in the dispersion fan (Murakami et al. 1991) have provided data on the fixation of U leached from the primary ore deposit. Their work has shown that, for this system, fractures are not only preferential pathways for ground-water movement but also contain secondary minerals with high sorption capacity for elements such as U. Even in the monsoonal climate, in which this deposit is located, a significant proportion of the uranium has not been released from the vicinity of the primary ore body.

Temperature is an important factor for bacterial activity and Pings (1968) set 35°C as the optimum operating temperature, which makes Australia s Northern Territory ideal. In Canada, however, it was found that heating of intake air was justified during winter months and, in France, bacterial leaching was absmdoned on the grounds of low temperature (Mouret, 1971).
