An assessment of the potential for magmatic-related uranium systems has been made using the fuzzy logic method ... The investigation has not attempted to identify specific sites of uranium mineralisation, but has rather focused on identifying igneous events and units which exhibit favourability for magmatic-related uranium systems. Potentially prospective units for each subcategory occur in all States and Territories. In many cases, identified prospective units occur in regions where uranium potential has been proven, including the Pine Creek, Curnamona and Georgetown-Cairns regions. Furthermore, potential has also been identified in regions not currently known for uranium mineralisation, including the Arunta, Musgrave and Halls Creek regions. The results of this study provide an initial tool for targeting magmatic-related uranium systems. This broad assessment should be further refined on a regional scale, making use of detailed local datasets and knowledge." --Executive summary.
